B‑Series 60 Permanent Magnet Servo Motor
Low losses and low electromagnetic noise – coils are neatly and tightly wound for optimal performance.
High protection and long service life – the stator injection‑molding process provides a withstand voltage of up to 3000 V without breakdown, faster heat dissipation, and an ingress protection rating of up to IP67.
Greater flexibility – low inertia makes the motors ideal for frequent high‑speed forward/reverse start‑up under load.
Smooth operation – the integrated stator welding process ensures a robust and rigid structure.
High encoder compatibility – supports a wide range of encoder types, including optical incremental, magnetic incremental, absolute, and resolver.
