What is a permanent magnet motor? Is there a difference between a regular motor
A permanent magnet motor is a permanent magnet. Only the rotor is a dc motor of the coil. The stator of an ordinary motor is a coil (electromagnet).
The difference between a permanent magnet and a conventional motor is: Magnetic field properties. Permanent magnet motors are made without the external energy to maintain their magnetic field; Ordinary motors require electricity to flow in to have a magnetic field. Rotor structure. The permanent magnet motor rotor is fitted with a permanent magnet. Excitation coil is installed on ordinary motor rotor. Applicable occasions. Permanent magnet motors are used for small power occasions; General motors, especially exciter motors, are often used in high-power situations. Electric machinery, electric machinery, is an electromagnetic device that realizes electrical energy conversion or transmission according to electromagnetic induction law. In the circuit, the letter M indicates that its main function is to generate drive torque as the power source of electrical or mechanical power.
A permanent magnet is a magnet that doesn't need to be charged by the current itself, and electromagnetic relays that require electrical flow to be magnetic. Permanent magnet motor and ordinary motor stator magnetic objects, not as electromagnetic relay, because the motor works by magnetic current ~ ~ hope to adopt building Lord ~! one
