MSM215-221-304-S-0KA

The MSM215-221-304-S-0KA is a high-performance brushless servo motor from Kollmorgen, part of the MSM Brushless Servo Motors series, engineered for demanding industrial automation applications. This robust unit delivers a nominal speed of 3000 RPM and supports a peak current of 65.1 A, providing a powerful balance of speed and torque. With a Motor Net Weight (kg) of 26.0 and a compact overall length of 367 mm, the motor integrates seamlessly into space-constrained systems without sacrificing performance. Built with a 6-Poles design, it offers exceptional dynamic response, making it ideal for precision motion control tasks in manufacturing and processing environments. Its durable construction and reliable operation ensure consistent performance under continuous load.

Featuring advanced electrical characteristics, the MSM215-221-304-S-0KA offers a Kt (Nm/Amp) of 1.36 and a Ke Voltage Constant (V/Krpm) of 164, enabling efficient conversion between electrical input and mechanical output. The winding assembly is optimized with a Winding Inductance Phase To Phase of 15.8 mH and a Winding Resistance Phase To Phase @ 25°C of 0.76 Ω, ensuring rapid current response and minimal thermal losses. The motor’s Stall Current (Amps Peak) of 20.5 allows for reliable starts under heavy load, while the robust Maximum Current (Amps Peak) of 65.1 accommodates brief surges in power demand. A Rotor Moment Of Inertia of 0.0074 kg·m² contributes to precise, responsive torque delivery, and the 6-pole configuration enhances torque density and smooth operation. These specifications combine to deliver superior control accuracy and energy efficiency in high-speed applications.

Operational reliability is reinforced by an operational Ambient Temperature (°C) range of 0 to 40 and a Storage Temperature (°C) range of -30 to 70, ensuring rugged performance in diverse environmental conditions. The motor supports a Radial Shaft Load Rating of 209 kg at 500 RPM, thanks to its precision-engineered ST-60 Shaft Material, which resists wear and deformation under heavy radial forces. A keyed shaft interface guarantees secure coupling to driven equipment, preventing slippage during high-torque operation. Compact dimensions—Flange Ø190 mm; Shaft Ø32 mm; Overall Length 367 mm—facilitate integration into tight spaces, while the 26.0 kg net weight maintains structural stability without imposing excessive load on mounting systems.
