Answer：Induction motors can generally be divided into cage type motors and wound type motors according to the structure of the rotor winding. Most of the cage-type rotor windings use cast aluminum rotors, that is, molten aluminum is cast in rotor core slots...
Answer：At present, China's motor manufacturing process is relatively mature, and the production automation of small and medium-sized motors is basically close to 100%. But why is the manufacturing process of large motors still so "backward"? Today
Answer：The broken shaft of the motor mostly occurs at the root of the shaft extension and the root of the bearing position at the end of the shaft extension. If there is a shaft fracture phenomenon in the motor, macroscopic observation and microscopic an...
Answer：The motor is an indispensable and important component in modern industry, and the performance of the motor often depends on the quality of the stator. The traditional motor stator is usually made of silicon steel sheet material.
Answer：Because three-phase or single-phase asynchronous motors use the principle of electromagnetic induction to transmit electric energy from the stator of the motor to the rotor through the coupling of the rotating magnetic field, and output mechanical en...
Answer：Changes in power supply voltage that are too high or too low have adverse effects on the motor. When the voltage is too high (higher than 10%), the iron core magnetic circuit is saturated (because when designing and manufacturing the motor, the magne...
Answer：The rotation of the stepper motor is to generate a rotating electromagnetic field on the stator through the electronic commutation of the stepper motor driver. Through the teeth of the stator and the rotor where the reluctance is the smallest, the ro...
Answer：In the process of motor production manufacturing, whether it is an established motor manufacturer or a rising star of a motor manufacturer, equipment investment and later upgrades have become an essential choice for enterprise development. Through in...
Answer：Phase-to-phase insulation is a special motor insulation performance requirement for multi-phase motors, that is, the insulation performance between coils of different phases of the motor winding must meet the electrical performance requirements of th...
Answer：From the output characteristics, motor speed regulation can be divided into two categories: stepless speed regulation and stepped speed regulation . When it comes to specific speed regulation methods, it can be said that there are many kinds. Ms. Ref...
