Permanent magnet synchronous motor and servo motor such difference
Jan 14, 2017

Permanent magnet synchronous motor is a kind of servo motor.

Ac servo motor and brushless motor, divided into synchronous and asynchronous motor, the current motion control with synchronous motor, in the scope of its power is big, can do a lot of power. Big moment of inertia, high rotational speed is low, and with the increasing power and fast. Thus suitable for the application of low speed running smoothly.

from the basic principle of permanent magnet synchronous motor and the traditional electric excitation synchronous motor is the same, the only difference for the traditional electric excitation synchronous motor is through the field winding zhongtong into electric current to generate the magnetic field, and the permanent magnet synchronous motor is established by permanent magnet of the magnetic field, and the resulting differences between the two analysis methods.
