Broadly speaking, a permanent magnet motor refers to a motor that uses permanent magnets. This type of electric du machine does not require excitation. It can be roughly divided into: permanent magnet DC dao motor (with commutator), brushless DC motor (DC motor) Characteristics, electronic commutation), permanent magnet synchronous motors (AC motor characteristics), etc.
Permanent magnet synchronous motors are just a classification of permanent magnet motors.
In addition, the classification of motors can be analyzed from multiple angles. From the principle point of view, they can be roughly divided into three categories: voltage control (direct torque control), such as brushed DC motors and brushless DC motors; frequency control (direct speed control), such as Induction motors and synchronous motors, etc.; magnetic field frequency control (using alignment principles), such as stepper motors.
