Product Description:
The MSM115-62-404-M-0KA is a brushless servo motor produced by Kollmorgen for the MSM Brushless Servo Motors series. Intended for industrial automation, the unit converts drive commands into precise rotary motion within closed-loop systems. This controlled motion allows machinery to position loads quickly and repeatably in material-handling, packaging, gantry, and robotic applications. Its brushless design uses electronic commutation, avoiding the mechanical wear associated with brushes while supporting responsive speed and torque regulation.
The motor delivers a continuous shaft torque of 7 Nm, which is the steady torque available without exceeding thermal limits. At a rated speed of 4000 rpm, this torque supports the power requirements of many packaging and material-handling axes. Electrical loading is limited by a maximum peak phase current of 26.9 A, while the stall condition draws 7.8 A peak to maintain position without rotation. The motor has a phase-to-phase voltage rating of 460 V and a voltage constant of 120 V/KRPM. This voltage constant indicates the back EMF that the drive must overcome as motor speed increases. A torque constant of 0.99 Nm/A relates commanded current to the torque produced by the motor. The six-pole stator establishes the magnetic field frequency, while a winding resistance of 3.4 Ω and an inductance of 16.8 mH limit current ripple. Multiturn high-resolution feedback supplies absolute position information to the controller, allowing the closed-loop system to track the shaft position across multiple revolutions.
Dynamic torque reaches 22 Nm, providing short acceleration bursts for indexing tasks before the motor returns to continuous operation. A rotor inertia of 0.0010 kg-m² supports rapid speed changes while maintaining stable motion under load. The winding inductance stores energy during operation, smoothing current transitions and reducing electromagnetic noise in the motor circuit. A keyed shaft provides positive mechanical engagement with compatible couplings, reducing the possibility of rotational slip during torque transmission. The motor has an overall mass of 8.5 kg, making it suitable for compact gantry assemblies and robotic joints where available mounting space and supported weight are limited.
