1. What are the application fields of three-phase motor?

Three-phase induction motors are mainly used in computer external equipment, lathe systems, photoelectric combination devices, valve control systems, nuclear reactors, surface grinding machines, CNC machine tools, automatic winding machines, electronic clocks and watches, medical equipment and other fields.

2. Hpw about the speed adjustment of three-phase induction motor?

Due to the induction motor, generally without a commutator, can be made into dc motor can not reach the large capacity, high speed, high voltage speed control system, in addition, for most without speed of fan and pump load, after adopting ac speed regulation, can further energy-saving, so for the induction motor's speed, energy saving research is of great significance.

3. What are the stator and rotor roommates made of?

Both stator and rotor are composed of iron core and winding.

Latest News

The rotor of the motor is composed of rotor core, rotor winding and shaft.

The rotor core is also part of the motor's magnetic circuit.

The action of rotor winding is to induce electromotive force and generate electromagnetic torque through current.

The shaft is the main component that supports the weight of the rotor, transmits the torque, and outputs the mechanical power.
