Glentek GM4050-38 Servo Motor

The GM4050-38 permanent magnet brush servo motor uses traditional ferrite magnets, which are ideal for cost sensitive applications. It also uses higher inertia armatures, 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 armatures, which provides low cogging torque and ultra smooth operation at all speeds. The GM4050-38 outputs up to 41.3 Lb-in (4.67 Nm) of continuous torque, and has a maximum speed of 3500 RPM. Industry standard English, metric, and NEMA mounting configurations are available.

GM series DC brush servo motors utilize traditional ferrite magnets, which are ideal for cost sensitive applications. In addition, the higher inertia armatures provide improved motor to load inertia matching for medium to high inertia loads. This helps to reduce the mechanical shaft resonance, which allows higher servo gains with increased stability. All frame sizes incorporate skewed armatures, which provide ultra smooth operation (i.e. low cogging torque) at all speeds.

  • Continuous Torque Range: 1.9 Lb-in (0.21 Nm) to 113 Lb-in (12.8 Nm)
  • Peak Torque Range: 12.0 Lb-in (1.4 Nm) to 338 Lb-in (38.1 Nm)
