The formation and harm of axial force in motor operation
Three-phase AC synchronous motor or asynchronous motor (hereinafter referred to as three-phase AC motor), when the stator winding is connected to the power supply, that is, a rotating magnetic field is generated, so that, for asynchronous motor, the rotor is induced current due to electromagnetic...Read More -
Control motors 5 major classifications
Control motors are mainly used for precise speed and position control and as “actuators” in control systems. They can be categorized into servo motors, stepper motors, torque motors, switched reluctance motors, brushless DC motors, and so on. 1. Servomotors Servo motors...Read More -
Large motor shaft voltage analysis and solutions
Four sets of bearings were replaced consecutively at the shaft extension end of a motor, which was eventually found to be due to shaft voltage. Shaft voltage is a frequent problem in the operation and testing of high-voltage and low-voltage high-power motors. In order to ensure the normal operati...Read More -
When selecting an inverter, is it necessary to consider the slot characteristics of the motor rotor?
For continuous changes in speed requirements for the conditions, will use a frequency converter to drag the motor, that is, through the motor power supply frequency changes, to achieve stepless adjustment of motor speed. In the original tweet we have talked about, through the frequency converter ...Read More -

Three-phase induction motors are one of the types and different from other types of electric motors. The mai...Read More -
Explosion-proof motor seat deformation causes?
Explosion-proof motor for a long time there will be some problems caused by the explosion-proof motor seat failure is mainly manifested in its deformation, explosion-proof motor seat deformation will directly affect the operation of explosion-proof motor. Explosion-proof motor seat deformation pr...Read More -
Why do motor rotors have closed slots?
With the continuous pursuit of motor efficiency, closed-slot rotors are gradually recognized by motor manufacturers. For three-phase asynchronous motors, due to the existence of stator and rotor grooves, the rotation will produce pulsation loss. If the rotor adopts closed slot, the effective air ...Read More -
Why do motors use double squirrel cage rotors
For motors of different uses, in addition to necessary parameters such as power, rated voltage, torque and speed, the matching relationship between the motor volume and the supporting equipment space is particularly important, especially for the case where the space to accommodate the motor is pa...Read More -
How can I prevent broken shaft problems in my electric motor?
For the analysis of the cause of the broken shaft problem, it should be the principle of preventing the occurrence of the broken shaft problem to reduce and eliminate the stress point and exclude the external factors. From the analysis of the construction characteristics of the shaft, from the de...Read More -
What are the characteristics of winding fault when three-phase motor lacks phase?
Under normal circumstances, the power supply and winding of the three-phase motor are symmetrical, when the power supply is out of phase or the motor is improperly connected, resulting in the motor input voltage is out of phase, it will cause the motor winding to appear regular burn phenomenon, o...Read More
