MS series - permanent magnet motors
Motors of MS series are large permanent magnet motors. The low voltage permanent magnet motor is a new type of synchronous motor for low speed applica¬tions, for use with variable speed drives. Mechanically, the motor type is similar to the tradi¬tional, induction, totally enclosed squirrel cage motor; even their outward appearance is same. However, in performance terms, it matches the accuracy of the traditional synchronous motor. They are designed to be reliable, efficient and cost effective. The new permanent magnet motor series extends the effective nominal speed range of the rugged industrial work-horses, the AC motor, down to 50 - 850 r/min. These motors simplify drive systems by effectively eliminating the need for speed reduction devices. The main application areas are as follows:
- Paper industry as roller and press drive
- Marine industry as propeller drive (main and auxiliary drives)
- Steel industry for worm drives, servo-press drives and drives for shears
- Plastics industry as drive for extruder worms, foil-drawing machines
- Crane industry for the widest range of applications
- Sugar industry for sugar centrifuges
