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
