MSM215-407-304-M-0KA by Kollmorgen

The Kollmorgen MSM215-407-304-M-0KA is a high-performance member of the MSM Brushless Servo Motors series designed to meet demanding industrial automation requirements. This brushless servo motor delivers a continuous torque of 46 Nm and a peak torque of 128 Nm, supporting dynamic motion profiles with a top speed of 3000 rpm. Its robust construction includes a shaft manufactured from ST-60 material, ensuring durability under heavy loads. Weighing in at 40 kg (88.2 lb) without a brake, the MSM215-407-304-M-0KA balances power density with structural integrity. The integration of a precision rotor moment of inertia of 0.0141 kg·m² contributes to the motor’s responsive control characteristics.

The MSM215-407-304-M-0KA’s detailed technical specifications provide insight into its electrical and mechanical design. Winding characteristics include a phase-to-phase inductance of 8.2 mH and a resistance of 0.28 Ohm @ 25°C, minimizing energy losses at rated load. The motor’s voltage constant of 170 V/krpm (KE) and torque constant of 1.4 Nm/A (KT) enable direct correlation between drive voltage, current, and shaft output. The six-pole configuration ensures smooth torque delivery and low cogging torque. Current-handling capability is robust, with a stall current of 36.6 A and a maximum peak current of 117.4 A for short-duration bursts.

Operational features emphasize consistent performance and thermal stability in continuous-duty applications. The motor’s compact 463 mm body length optimizes installation space while accommodating forced-air or liquid cooling arrangements. Peak torque of 128 Nm can be sustained in intermittent operation without thermal overload, while continuous torque of 46 Nm supports extended run times under high-load conditions. For safety and holding applications, the optional electromagnetic brake increases net weight to 43 kg and rotor inertia to 0.0171 kg·m², providing reliable stoppage under fault conditions. The balanced rotor design and low inertia contribute to rapid acceleration and deceleration, enhancing cycle rates in automated systems.

System integration is streamlined by the MSM215-407-304-M-0KA’s compatibility with industry-standard servo drives and feedback modules. Its precise electrical constants and mechanical tolerances facilitate direct-drive implementations in CNC machinery, robotic arms, and packaging lines. The motor’s robust shaft material and sealed bearing arrangements reduce maintenance intervals in harsh environments. By combining advanced electrical performance with mechanical reliability, this Kollmorgen servo motor is ideal for industrial automation and high-precision motion control applications.
