The main function of the motor is to provide drive energy is the corresponding mechanical equipment operation.
Motor refers to an electromagnetic device which can convert or transfer electric energy according to the law of electromagnetic induction. Motor is a kind of electric energy can be converted into mechanical energy.
The motor uses an energized coil to generate a rotating magnetic field and acts as a rotor cage type closed aluminum frame to form a magneto-electric rotating torque. It has fast response, large starting torque, and can provide rated torque from zero to rated speed.
Since the motor must generate constant torque energy at rated load, the armature and rotor magnetic fields must be kept at a constant 90°, which requires carbon brushes and commutators. As the motor rotates, the brush and commutator produce sparks and toners. Therefore, in addition to causing component damage, the use is also limited.
