Permanent magnet synchronous servo motors are the servo motor which use permanent magnets and are divided into SPM (surface permanent magnet synchronous motors) and IPM (interior permanent magnet synchronous motors).
The synchronous servo type produced by Fukuta is SPM. The surface type permanent magnet motor has a simple structure. The magnet is glued or fixed on the surface of the rotor. The location which do not have magnets of the rotor, there is a wide air gap between the stator. The current Fukuta permanent magnet series products are divided into general permanent magnet synchronous servo motor and direct drive permanent magnet synchronous servo motor.
