GMBF4320-100 Servo Motor

The GMBF4320-100 permanent magnet brushless servo motor uses traditional ferrite magnets, which are ideal for cost sensitive applications. It also uses higher inertia rotors, which provide improved motor to load inertia matching for medium to high inertia loads. This helps reduce mechanical shaft resonance and leads to higher servo gains for increased stability. In addition, this motor incorporates a skewed stator, which provides low cogging torque and ultra smooth operation at all speeds. The GMBF4320-100 outputs up to 22 Lb-in (2.49 Nm) of continuous torque, and has a maximum speed of 1800 RPM. Industry standard English, metric, and NEMA mounting configurations are available.
