Outer Rotor & Stator


Ø Rotor

In an electric motor, the moving part is the rotor which tums the shaft to deliver the mechanical power. The rotor usually has conductors laid into it which carry currents that interact with the magnetic field of the stator to generate the forces that turn the shaft. However, some rotors carry permanent Magnets, and the stator holds the conductors.

Ø Stator

The stationary part is the stator, usually has either windings or permanent magnets. The force between the two magnetic fields tends to rotate the motor shaft. The commutator switches power to the coils as the rotor turns, keeping the magnetic poles of the rotor from constant aligning with the magnetic poles of the stator field, so that the rotor never stops(like a compass needle does), as long as power is applied.

Ø Application

1.Small in size, high control precision: Floppy disk driver, driver, Hard disk driver,Memory drum electromotor, Tape servo system.

2.Good speedability, High positioning accuracy, Big starting torque, Strong overload capacity: CNC machine systems, the robot control system.

3.Transportation: Electrical Blcycle, Electric Vehicle, Hybrid Vehicle, City Tram.

4.High unit volume power density: Such as Refrigeratcr. Air conditioner and other Household electrical appliances.
