Answer：Once the permanent magnet motor loses its magnetism, basically you can only choose to replace the motor, and the maintenance cost is a lot. How to judge the loss of magnetism of the permanent magnet motor, let's look down.
Answer：Recently, Aion released the quark electric drive technology, which increased the power density of the motor to 12kW/kg for the first time, significantly ahead of the industry mainstream 6kW/kg level. Just a palm-sized motor can burst out super power ...
Answer：A stepper motor is a motor that rotates a shaft by taking steps (that is, moving at a fixed angle). Its internal construction allows it to know the exact angular position of the shaft through simple step counting without a sensor, making it suitable ...
Answer：Motor braking is a problem often encountered in motor control. Generally, motor braking will appear in two different occasions. One is to achieve the purpose of rapid parking, and use various methods to make the rotation direction of the motor's...
Answer：As a bright pearl of motor technology, servo motors have been developed in China for more than ten years. Up to now, there is no enterprise focusing on the research and development and production of servo motors among A-share listed companies. A-shar...
Answer：Vertical type and horizontal type are relatively common installation types of motor products. From the appearance and structure of the motor, the base and end cover of the two types of motors will have obvious differences. Horizontal motors are main...
Answer：Compared with asynchronous motors, permanent magnet synchronous motors have obvious advantages. It has high efficiency, high power factor, good capacity index, small size, light weight, low temperature rise, and remarkable technical effect, which can...
Answer：For the safety of amusement facilities, manufacturers usually use high-strength bolts to fix the motor. For commonly used motors, the number and size of the motor base have been determined before leaving the factory, and ordinary bolts can meet the d...
Answer：The magnetic circuit is similar to the circuit, and the magnetic steel and the power supply can be compared. Only the thickness is increased, and the magnetic flux corresponding to the residual magnetism remains unchanged, but the internal reluctance...
Answer：The motor shaft is hollow, the heat dissipation performance is good, and the weight of the motor can be reduced. In the past, the motor shaft was mostly solid, but because the stress of the motor shaft was often concentrated on the surface of the sha...
