Interpretation of the core knowledge of the wall-breaking machine motor

I. What is the wall-breaking machine motor? ​

The wall-breaking machine motor is a key component that provides power for the wall-breaking machine. It converts electrical energy into mechanical energy to drive the blade to rotate at high speed to crush and mix the ingredients. It is like the "heart" of the wall-breaking machine, and its performance is directly related to the working effect and service life of the wall-breaking machine. ​

II. What are the types of wall-breaking machine motors? ​

Universal motor: It can work under AC and DC power supply, has high speed and high torque, can easily meet the crushing needs of various ingredients, and is commonly found in a variety of wall-breaking machine products. For example, some traditional wall-breaking machines, relying on the strong power of universal motors, can effectively break the walls of hard ingredients such as nuts and beans. However, universal motors also have their disadvantages. There is mechanical contact between the brush and the commutator, which will generate more heat and wear when running at high speed, resulting in limited motor life, and the running noise is large, which affects the user experience to a certain extent. After long-term continuous use, the brush wear is aggravated and sparks may occur, which not only reduces the performance of the motor, but also poses a safety hazard.​

Brushless DC motor: This is the most advanced type of motor at present. It abandons brushes, reduces friction loss, and can achieve an efficiency of over 85%. Not only that, it is extremely quiet when running and has a long service life, usually up to tens of thousands to hundreds of thousands of hours. Some mid-to-high-end wall-breaking machines use brushless DC motors, which not only achieve efficient wall-breaking, but also reduce noise interference, bringing users a more comfortable experience. The brushless DC motor replaces the traditional brush commutation with an electronic commutator, avoiding the performance degradation caused by brush wear, and greatly improving the operating stability. However, due to its relatively complex technology and high production process requirements, it leads to high costs, so it is rarely used in some relatively affordable wall-breaking products. ​

Switch reluctance motor: The motor has a simple structure, strong stability at high speed, and can adapt to harsh working environments. Its winding technology is simple, the cost is low, and it has good fault tolerance, large starting torque, small current, and various speed regulation and control methods. In some wall-breaking machines with special performance requirements, the switched reluctance motor plays a unique advantage and improves the overall technical performance level of the wall-breaking machine. However, the switched reluctance motor will generate large torque pulsation during operation, resulting in relatively large operating noise. It may not be suitable for kitchen scenes with extremely high requirements for noise control. In addition, its speed regulation range is relatively narrow, and its flexibility is slightly insufficient in some cases where the speed needs to be precisely controlled to adapt to the wall-breaking needs of different ingredients. ​

III. What is the impact of motor parameters on the performance of the wall-breaking machine? ​

Power: The power determines the output capacity of the motor. The power of common wall-breaking machine motors is 500-2000 watts. The higher the power, the stronger the crushing force, and it is easier and more efficient to handle hard ingredients such as ice cubes and large nuts. For example, a 1500-watt wall-breaking machine can beat ingredients more delicately in a shorter time than a 1000-watt one. However, the higher the power, the better. High-power motors consume more energy during operation, and at the same time, they have higher requirements for the overall structure and cooling system of the wall-breaking machine. If the heat dissipation of the machine is not good, long-term high-power operation will cause the motor to overheat, accelerate the aging of the internal components of the motor, and shorten the life of the motor. In a household power environment, a wall-breaking machine with too high power may also cause a certain impact on the power grid, and the carrying capacity of the household line needs to be considered. ​

Speed: The speed is generally above 10,000 rpm, and high-performance motors can even reach 30,000 rpm. High speed enables the blade to generate a strong impact force in an instant, greatly improving the wall-breaking effect, making the ingredients more finely crushed and the nutrients released more fully. Taking the production of fruit and vegetable juice as an example, a wall-breaking machine driven by a high-speed motor can fully break the cell walls of fruits and vegetables, making the taste of fruit and vegetable juice more delicate and the nutrients easier to absorb. However, too high a speed may also bring some problems. High-speed operation will increase the friction between the blade and the ingredients, which will not only accelerate the wear of the blade, but also cause local overheating of the ingredients, affecting the nutritional content and taste of the ingredients. For example, when making fruit and vegetable juice containing heat-sensitive nutrients (such as vitamin C), the high temperature generated by too high a speed may destroy some nutrients. In addition, high-speed operation will also increase the noise and vibration of the motor operation, posing higher challenges to the stability and noise reduction design of the wall-breaking machine.​

Torque: Torque reflects the rotational torque output by the motor. With large torque, the motor is not easy to get stuck when facing hard ingredients, which can ensure that the crushing process is smooth and smooth. For example, when grinding dry beans to make soy milk, a large torque motor can ensure the stable operation of the cutter head, crush the beans evenly, and avoid the situation where some beans are not ground. If the motor torque is insufficient, when processing hard ingredients, the motor is prone to overload, the speed drops or even stops, not only can the ideal wall-breaking effect not be achieved, but the motor may also burn out due to long-term overload operation. However, excessive torque may also cause unnecessary energy waste in some cases, and the transmission components of the wall-breaking machine are required to be higher, which increases the manufacturing cost and maintenance difficulty of the machine. ​
IV. How to maintain the wall-breaking machine motor? ​

Cleaning in time: After use, the oil stains, food residues, etc. on the surface of the motor should be cleaned as soon as possible to prevent them from entering the motor, affecting the normal operation of the motor, and reducing the probability of failure. When cleaning, be careful not to use an overly damp rag to prevent moisture from entering the motor and causing a short circuit. You can first wipe off large stains on the surface with a dry cloth, and then gently wipe off the remaining stains with a slightly damp and wrung soft cloth. For key parts such as the motor vents, you must clean them carefully to ensure smooth ventilation and avoid poor heat dissipation of the motor due to blockage by debris. ​

Avoid long-term continuous use: long-term continuous operation will cause the motor to overheat and shorten its service life. Generally speaking, the single continuous use time should not exceed the time specified in the product manual. If you need to use it multiple times, it is recommended to wait for a certain period of time to let the motor cool down before running. Motors of different types and powers have different heat dissipation capabilities and continuous working times. For example, general motors have relatively poor heat dissipation and usually have shorter continuous working times; while brushless DC motors have better heat dissipation performance and can appropriately extend the continuous working time. Users must follow the product instructions when using it, arrange the use time reasonably, and protect the performance of the motor. ​

Pay attention to the operating status: In daily use, pay attention to whether there are abnormal noises, excessive vibrations, or a significant drop in speed when the motor is running. Once an abnormality is found, stop using it immediately and contact a professional for repair. Do not disassemble it yourself to avoid causing more serious damage. Abnormal noise may be caused by wear, looseness or foreign matter entering the internal parts of the motor; excessive vibration may mean that the motor is not installed stably or that parts such as bearings are faulty; a drop in speed may be caused by motor overload, unstable power supply voltage or internal circuit problems. Timely detection and treatment of these problems can effectively avoid further damage to the motor and extend its service life. ​

V. What are the common faults of the wall-breaking machine motor and how to solve them? ​

The motor does not rotate: Possible reasons include power supply problems, such as the plug is not plugged in properly, the power cord is damaged, the socket is faulty, etc.; the motor itself is faulty, such as winding short circuit, open circuit, rotor stuck, etc.; control circuit failure, such as switch damage, circuit board component burnout, etc. The solution is to first check the power connection, make sure the plug is plugged in tightly, replace the socket for testing, and if the power cord is damaged on the outside, replace the power cord. If the power supply is normal, you can further check whether the motor appearance is obviously damaged, and try to manually turn the motor shaft to see if it is flexible. If the motor shaft is stuck, there may be foreign matter inside, which requires professional disassembly and cleaning. For control circuit problems, it is difficult for non-professionals to troubleshoot them by themselves. It is recommended to send it to a professional maintenance organization for repair. The maintenance personnel will use professional tools to detect the circuit board components and replace the damaged parts. ​
Unstable motor speed: It may be that the motor brushes are severely worn, resulting in poor contact; the power supply voltage fluctuates greatly; the electronic speed regulator inside the motor is faulty, etc. If it is due to brush wear, the remaining length of the brush can be observed. When the brush is worn to less than one-third of the original length, the same type of brush needs to be replaced in time. For power supply voltage problems, a multimeter can be used to measure the power supply voltage. If the voltage fluctuation exceeds the rated voltage range of the wall breaker (generally 110V-240V), it is necessary to check the household power environment and whether there are high-power electrical appliances in use at the same time. If necessary, install a voltage stabilizer to stabilize the voltage. If the electronic speed regulator is suspected to be faulty, the wall breaker needs to be sent for repair, and a professional will detect the speed regulator circuit and repair or replace the faulty components. ​

Motor overheating: Common causes include motor overload, such as putting too much food in at one time, and the food is too hard to crush; poor motor heat dissipation, such as blocked vents and cooling fan failure; quality problems of the motor itself, such as excessive winding resistance. To solve the problem of motor overheating, first check the amount and hardness of the ingredients to avoid overloading. If the motor does not dissipate heat well, clean the vents and check whether the cooling fan is operating normally. If the fan is damaged, replace it in time. For overheating caused by motor quality problems, if the wall breaker is within the warranty period, contact the manufacturer's after-sales service to replace the motor; if the warranty period has expired, you can find a professional maintenance personnel to evaluate whether it is worth repairing. If the repair cost is too high, you can consider replacing a new wall breaker. ​
