Product Description:
The MSM215-319-304-E2-2KA is a brushless servo motor produced by Kollmorgen within the MSM Brushless Servo Motors series. Its permanent-magnet design supports closed-loop motion control for positioning tables, automated presses, packaging equipment, and other machinery that requires accurate torque across a variable speed range. A 24 VDC integral brake holds connected loads when motor power is removed, helping prevent unwanted shaft movement while an axis is stopped. The motor has an overall length of 415 mm, allowing it to fit medium-frame machinery without additional shaft spacers.
This model supplies a continuous shaft output of 36 Nm and reaches a rated speed of 3000 rpm, allowing applications to maintain steady motion while remaining within the motor’s thermal limits. Its 460 V winding draws 28.7 A at stall and up to 93.3 A during acceleration. The voltage constant of 164 V/KRPM relates rotational speed to the back electromotive force generated by the motor. An optical encoder with 2,000 lines sends position data to the controller, supporting accurate velocity regulation and repeatable positioning. Dynamic performance is aided by a rotor inertia of 0.0138 kg-m², which supports rapid changes in direction while helping the controller limit overshoot. The motor has a torque constant of 1.36 Nm/A, relating applied drive current to the torque produced at the shaft. A male shaft end tapped for an M12 × 1.75 mm fastener simplifies attachment to compatible pulleys or rigid couplings.
For intermittent demand, the motor develops a peak torque of 100 Nm, supporting brief overloads during rapid indexing or material shearing operations. Its 10.6 mH phase inductance moderates the electrical response as current changes in the windings. Copper losses are affected by a 0.40 ohm phase resistance, which the drive controller must account for when regulating current and managing heat. The assembled motor, including its brake, weighs 36 kg, so the mounting surface and lifting arrangement must accommodate the complete unit. The rigid housing helps limit unwanted movement when the motor experiences rapid torque changes during demanding motion cycles.
