MSM215-505-304-E2-2KA by Kollmorgen

The Kollmorgen MSM215-505-304-E2-2KA is a high-performance member of the MSM Brushless Servo Motors series, engineered to deliver reliable motion control in demanding industrial environments. This robust servo motor offers a continuous torque of 57 Nm paired with a peak torque of 160 Nm, ensuring consistent power delivery under heavy loads. With a maximum speed of 3000 RPM, it supports rapid acceleration and precise positioning tasks. The motor’s ST-60 shaft material and substantial motor net weight of 49 kg guarantee mechanical stability and vibration damping. Designed by Kollmorgen, this part integrates seamlessly into industrial automation systems requiring robust and reliable drive solutions.

Featuring advanced electrical and mechanical specifications, the MSM215-505-304-E2-2KA excels in technical capability. The torque constant (Kt) of 1.39 Nm/amp and voltage constant (Ke) of 168 V/krpm optimize responsiveness and control accuracy. It sustains a maximum current of 147.1 A peak and a stall current of 45.5 A, enabling high-torque starts and dynamic load changes. The six-pole configuration (Poles: 6) enhances low-speed torque smoothness while the winding inductance phase-to-phase of 6.5 mH and winding resistance of 0.24 Ohm at 25°C are tuned for efficient heat dissipation and minimal electrical losses. This combination of electrical characteristics ensures stable operation across the entire speed range.

Operationally, the MSM215-505-304-E2-2KA delivers exceptional reliability and low-maintenance performance. Its rotor moment of inertia of 0.0175 kg-m² (with brake: 0.0205 kg-m²) provides quick dynamic response and reduced overshoot in precision positioning. The brushless design eliminates brush wear, lowering lifecycle maintenance requirements and downtime. The motor’s substantial mass and integrated brake option (weighing 52 kg with brake) further enhance load holding and positional stability in vertical or torque-critical applications. The durable ST-60 shaft ensures secure torque transmission through the integral keyway, preventing slippage even under shock loads.

Designed for straightforward integration, the MSM215-505-304-E2-2KA features standardized mounting interfaces and compatibility with Kollmorgen’s range of servo drives and motion controllers. Its robust construction and precise feedback characteristics make it ideal for robotics, CNC machining centers, packaging machinery, and other automated production lines. Engineers can leverage the motor’s high torque density and rapid acceleration to optimize cycle times and throughput. With its combination of power, precision, and reliability, this servo motor addresses the most demanding industrial automation challenges.
