The SIEMOSYN^® 1FU8 motors are permanent magnet excited synchronous motors with a squirrel-cage winding for asynchronous self-starting. They can be operated as constant-speed drives on the mains, or as variable-speed single-motor or multi-motor drives on the inverter.

For preference, the SIEMOSYN 1FU8 motors are supplied with the SIMOVERT^® MASTERDRIVES, or SINAMICS^® ranges of converters, or with MICROMASTER^® inverters.

The mechanical design (size, housing, end plates, shaft dimensions, etc.) is identical to that of the 1LA7 three-phase conventional motors (IEC standard).

The motors are available as standard up to a speed of 15,000 min^-1. A constant drive torque is available within a large frequency/speed range.
