The permanent magnet motor range extends the effective nominal speed range of the rugged industry workhorses down to 100 – 850 r/min. The motors can simplify drive systems by effectively eliminating the need for speed reduction devices. They are designed exclusively for frequency converter supply, where they provide high-speed accuracy even without speed sensors because they are synchronous motors without rotor slip.

Features

 

• Torque range 1000 to 50 000 Nm

• Construction based on standard induction motor design

• Rotor magnetization by permanent magnets

• Totally enclosed IP 55 construction

• Air- or liquid cooled
   

The most common present drive systems, which permanent magnet motor solution could replace:

• Traditional AC motor, frequency converter and gearbox combination

• Traditional slow speed AC motor, typically 10-16-pole or slower with frequency converter

• Variable speed DC drive system with gearbox
