Internal Product Review
The MSM100-6-604-S-2KA is a Kollmorgen brushless servo motor rated for 460 V and 6000 rpm. Continuous output is well balanced at 0.72 N·m with a 3.8 N·m peak torque capacity, making the motor especially capable in dynamic motion applications. Single-turn high-resolution feedback stands out as a key advantage for precise position control.

Product Description:
The MSM100-6-604-S-2KA is a brushless servo motor produced by Kollmorgen within the MSM Brushless Servo Motors series. It is intended for precision industrial automation where rapid positioning and velocity control are required, such as indexing tables or compact pick-and-place axes. The motor integrates a high-resolution, single-turn feedback element for closed-loop regulation and includes an electromechanical brake powered by the machine’s 24-volt control bus. The feedback system provides the drive with rotor position data for accurate speed and position adjustments during operation.
The holding brake accepts 24 V DC, allowing it to hold the shaft when the motor is stopped. During continuous duty, the stator can sustain 0.72 N·m of torque, while peak thermal loading is limited by a maximum phase current of 9.3 A peak. At the rated speed of 6000 rpm, the six-pole rotor develops synchronous rotation with a line-to-line back EMF that corresponds to the motor’s 55 V/krpm voltage constant. Operation is supplied from a 460 V bus, matching common three-phase drives without requiring a step-down transformer. The winding resistance is 24.4 Ω, and the torque constant is 0.46 N·m/A; these electrical values affect current response and drive tuning. A stall current of 2.0 A peak indicates the continuous current level that must be considered when managing motor temperature.
For rapid load changes, the motor can deliver a peak torque of 3.8 N·m, aided by a rotor inertia of only 0.00026 kg·m². The low rotor inertia reduces servo lag during acceleration, deceleration, or direction reversal. The output shaft is ground to a diameter of 14 mm, providing a direct fit for compatible couplings, and its keyway provides positive engagement with the connected load. Net mass, including the brake assembly, is 5.6 kg, so the mounting surface must support that static load. An electrical inductance of 48 mH reduces current ripple under pulse-width-modulated drive signals. The six magnetic poles also support smooth torque production at low speeds when the drive receives accurate position feedback.
