Servo & Electric Drives
AC Permanent-Magnet Servo Motors
Permanent-magnet AC servo motors from 0.2 to over 400 kW.
Sinusoidal permanent-magnet synchronous AC servo motors for industrial machinery, including the high-torque motors that drive the pump on servo-hydraulic (energy-saving) injection molding machines and presses. The range runs from small naturally cooled motors to large fan-, water- or oil-cooled frames, with resolver feedback as standard and encoder options. Motors can be supplied matched to servo drives from the same line.
