Permanent magnet motor - Wikipedia
A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.

What is Permanent Magnet DC Motor (PMDC Motor)?
2023年11月14日 · Permanent magnet motors are similar to conventional DC motors except the use of permanent magnet to produce flux instead of field winding.
Permanent Magnet Motor - an overview | ScienceDirect Topics
Permanent-magnet (PM) motors have a stator winding configuration similar to the three-phase induction motors, but they use permanent magnets in the rotor instead of a squirrel cage or wound rotor.
Control Techniques | What is a permanent magnet motor? - Nidec
2016年11月15日 · Today Permanent Magnet Assisted Synchronous Reluctance Motor (PMASynRM) & nanocomposite permanent magnets are used. The advantages of adding permanent magnets to the synchronous reluctance motor rotor construction are the increased motor power factor and thus reduced motor stator Ohmic losses.
Types and Characteristics of Permanent Magnet Motors
Permanent magnet motors use permanent magnets as the magnetic field, which can maintain their magnetic field without external energy, while ordinary motors require current to have a magnetic field.
