Product Description:

The AM237M-1020 is a synchronous servo motor manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. It is intended for integration into multi-axis assemblies where precise rotary positioning is required. The motor uses an OCT multi-turn feedback system that carries encoder data and power through the same cable, reducing connector count and simplifying cabinet layout. In typical industrial automation cells, the device drives indexing tables, linear stages with belt reduction, or compact gantry axes. Its compact arrangement is useful where installation space is limited and cable routing must remain straightforward.

During continuous operation, the motor delivers a rated mechanical output of 0.5 kW at a shaft speed of 6000 rpm. These values are achieved with a rated current of 1.5 A and a rated torque of 0.8 Nm, while the electromagnetic design allows a peak current of 6.5 A for short accelerations. Torque production scales with a torque constant of 0.62 Nm/A, and the back EMF follows a voltage constant of 38 V per 1000 rpm, which helps with drive sizing and controller tuning. The 21 mH winding inductance and 12.8 Ω resistance shape the electrical response, and the motor has a thermal time constant of 15 minutes. This balance supports quick response without making the electrical behavior difficult to control.

The motor has a standstill torque of 1 Nm, which helps maintain position when velocity commands are zero. The flange measures 194 mm and accepts axial forces up to 90 N and radial forces up to 270 N, enabling belt or pinion loads without additional support bearings. The rotating mass is limited to 0.7 kg·cm², supporting fast reversals in compact motion systems. A shaft with a groove and feather key produced to DIN 6885 transmits torque, and the motor is supplied without a holding brake to minimize length and inertia. This layout suits applications that need direct mechanical coupling and frequent direction changes.
