Product Description:

The 6SM 37M-6.000-G synchronous servo motor is manufactured by Kollmorgen within the 6SM Synchronous Servo Motors series. Intended for precision motion axes in automated assembly, packaging, and electronics machinery, the unit transforms three-phase electrical energy into tightly regulated rotational output. Combined with a matched servo amplifier and feedback device, it supplies the positioning accuracy, velocity stability, and duty-cycle flexibility typically required in light mechanical stages and compact rotary actuators.

The motor is optimized for operation from industrial supplies rated at 400/460 V, allowing connection to common machine control cabinets. Under continuous load, it draws a phase current of 1.5 A and delivers 0.5 kW to the shaft. At that operating point, the rotor reaches 6000 rpm and generates 0.8 Nm of torque for sustained motion profiles. The design keeps static friction at 0.02 Nm, supporting smooth operation at low speeds. It also provides a standstill torque of 1 Nm with a holding current of 1.6 A. A torque constant of 0.62 Nm/A establishes a linear relationship between drive current and produced torque. The windings have a thermal time constant of 15 minutes, which delays temperature increases during cyclic operation.

For rapid indexing, the drive can elevate phase current to 6.5 A, providing short-term torque reserves beyond the continuous rating. Current slew is moderated by a phase inductance of 21 mH, allowing the controller to issue fast yet stable command steps. Together with a phase resistance of 12.8 Ω, this inductance establishes the electrical time constant used when tuning current loops. Mechanical dynamics benefit from a rotor inertia of 0.7 kg·cm², enabling swift acceleration without excessive overshoot. A 24 VDC holding brake secures the load when power is removed. The back-EMF constant of 38 V/1000 rpm allows the motor to work with compatible servo drives and supports energy recovery during deceleration.
