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

The MSM215-407-304-S-0KA servo motor is a high-performance solution from Kollmorgen, part of the MSM Brushless Servo Motors series, engineered for precise speed and torque control in industrial automation. This compact unit delivers a continuous output of Continuous Torque: 46 Nm (407 in-lb) and sustains a Peak Torque: 128 Nm (1133 in-lb) during dynamic operations. With a top speed of Speed: 3000 rpm, it meets the demands of moderate-speed positioning applications, while its Rotor Moment Of Inertia: 0.0141 kg-m² (0.1248 lb-in-s²) supports smooth acceleration and deceleration profiles. The motor’s robust construction yields a Motor Net Weight: 40 kg (88.2 lb), balancing structural rigidity with manageable mass for system integration. Designed for continuous duty, this servo motor combines mechanical resilience and power density in a single package.

Featuring advanced electrical characteristics, the MSM215-407-304-S-0KA excels in performance and responsiveness. The Ke Voltage Constant: 170 V/KRPM ensures linear voltage-to-speed conversion for accurate velocity control, while the Kt (torque Constant): 1.4 Nm/Amp directly links current input to torque output. Phase-to-phase Winding Resistance: 0.28 Ohms (25°C) and Winding Inductance: 8.2 mH define the motor’s electrical time constant, optimizing current rise and minimizing thermal losses. It supports a Maximum Current: 117.4 amps peak for short-term overloads and a Stall Current: 36.6 amps peak to maintain torque under heavy load starts. The integrated design ensures minimal cogging torque and consistent performance across wide operating ranges, making it ideally suited for repeatable positioning tasks and dynamic motion sequences.

Reliability and integration are central to the MSM215-407-304-S-0KA’s design. The shaft, constructed from Shaft Material: ST-60, withstands radial and axial loads in precision indexing and direct-drive applications. The servo motor accommodates optional braking with a Motor Net Weight With Brake: 43 kg (94.8 lb) without compromising dynamic response. It is rated for Storage Temperature: -30 to 70°C (-22 to 158°F), ensuring durability in varied environmental conditions and facilitating deployment in outdoor or temperature-sensitive installations. When paired with Kollmorgen drives and controllers, this motor enables seamless integration into multi-axis systems for packaging, robotics, CNC machinery, and other high-precision industrial automation solutions.
