Servomotors 1FU

Permanentmagneterregte Synchronmotoren, SIEMOSYN 1FU8

The 1FU8 SIEMOSYN motors are permanent-magnet synchronous motors with short-circuit cage for an asynchronous automatic start. They can be operated on the supply system as drives with constant speed or on a converter as variable-speed, single or group drives. The SIEMOSYN motors are used where generally high demands are placed on the speed constancy and the accuracy of the synchronous operation of several motors in a motor grouping.

1FU8 permanent-magnet synchronous motors - for single and group drives

Speed synchronism and accuracy
Motors in group drives run synchronously without additional work; the motor speed is independent of the load
Low cabling and installation costs
The motors do not require a speed encoder
High efficiency - low losses
Low rotor and exciter losses compared to induction motors because of the operating principle
High maximum speeds up to 15,000 rpm
