GLENTEK: GM4000 series DC brush servo motors GM4020-25-XXXXXXXX-XXXX

To accommodate your complete servo system requirements, Glentek manufactures two complete series (GM and GMR) of high performance, permanent magnet DC brush servo motors.
Following is a general description of each series:
GM SERIES
The GM series 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)
GMR SERIES
The GMR series utilize high-energy Neodymium-Iron-Boron (NdFeB) magnets, which provide more torque in a smaller package with higher dynamic performance than traditional ferrite magnet designs. Due to the high torque to inertia ratio of these motors, they are ideal for applications which require high acceleration and deceleration characteristics or where the physical size of the motor is a major concern.
• Continuous Torque Range:16.0 Lb-in (1.81 Nm) to 65.0 Lb-in (7.34 Nm)
• Peak Torque Range:80.0 Lb-in (9.04 Nm) to 325.0 Lb-in (36.72 Nm)
GM SERIES
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.
Glentek’s DC brush servo motor line features high performance, skewed armatures, and TENV construction. Industry standard mounting, feedback, sealing, and lead termination options available, along with optional fail safe brakes.

GM4000 SERIES
Glentek’s GM4000 series of high performance, permanent magnet 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. These motors incorporate skewed armatures, which provide ultra smooth operation (i.e.low cogging torque) at all speeds.
• Continuous Torque Range: 13.0 Lb-in (1.47 Nm) to 51.2 Lb-in (5.78 Nm)
• Peak Torque Range: 65.0 Lb-in (7.35 Nm) to 256.0 Lb-in (28.9 Nm)

The GM4020-25 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 GM4020-25 outputs up to 23 Lb-in (2.6 Nm) of continuous torque, and has a maximum speed of 4000 RPM. Industry standard English, metric, and NEMA mounting configurations are available.
