Description

Technical Parameters

A Permanent Magnet Synchronous Spindle Motor is usally a direct-drive AC Servo motor to drive the spindle of a machine tool. The spindle motor requires high precision and high torque and high rotation spindle depending on machine tool specificaiton. Permanent Magnet Synchronous Spindle Motor integrates the rotor and spindle shaft into a single unit, eliminating the need for belts, gears, or couplings.

Typical application

High-Speed Machining Center, Precision Grinding & Jig Grinding Machines, Turn-Mill Centers & Swiss-Type Lathes and Precision Boring & Honing Machines.
