The pm-excited reluctance motors are an alternative to the reluctance motors and can be used in identical applications typical for synchronous motors.
PM-reluctance motor for godet drive
They differ to the reluctance motors by the pm-magnets which are implemented inside the rotor body (NeFeB). These magnets allow a higher utilisation of motors togehter with impoved electric figures (less current consumption, higher power factor and efficiency).
Pm-motors contain a higher moment of inertia, for applications which include an acceleration of large external moments of inertia, special testing might be usefull. Pm-motors are available 4-pole in metric frames 63 to 80.
