Product Description:

The MSM215-319-304-M-0KA is a brushless servo motor produced by Kollmorgen within the MSM Brushless Servo Motors series. Acting as a rotary actuator, it delivers commanded position, velocity, and torque to automated machinery and forms a closed-loop axis when paired with a matching servo drive. Typical applications include material-handling gantries, packaging stations, and general motion systems where repeatable high-torque output is required.

The winding set produces a continuous torque of 36 Nm, while short duty cycles can reach a peak torque of 100 Nm for rapid acceleration. These torque values are produced by a six-pole rotor that can rotate at up to 3000 rpm when supplied from a 460 V DC bus through a sinusoidal drive. During acceleration, the phase conductors can accept a maximum current of 93.3 A peak, whereas static shaft loading that locks the rotor raises current demand to 28.7 A peak at stall. The electromagnetic circuit has an inductance of 10.6 mH and a resistance of 0.40 Ω, which influence current rise time and copper losses. These values assist with drive sizing, bus capacitor energy storage calculations, and thermal modeling for continuous operation.

Mechanical integration is supported by a forged ST-60 steel shaft that ends in an M12 × 1.75 mm threaded tip for positive coupling. The rotor has a moment of inertia of 0.0108 kg·m², balancing dynamic response with load stability, and the motor has a total mass of 33 kg for machine or gantry loading calculations. Multi-turn high-resolution feedback reports absolute position across multiple revolutions, simplifying homing after power cycles. The back EMF slope is 164 V/KRPM, indicating the voltage generated in relation to rotational speed. The magnet-to-coil geometry produces a torque constant of 1.36 Nm/A, allowing the drive to convert commanded current into predictable mechanical output.
