Product Description:
The MSK061B-0300-NN-S1-UG1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, this motor converts controlled electrical energy into precise rotary motion for coordinated axis movement in packaging lines, pick-and-place systems, and CNC equipment. It is intended for closed-loop operation with compatible IndraDrive controllers, which use integrated feedback to monitor rotor position and regulate torque during changing load conditions. This arrangement supports accurate starts, stops, and speed changes in applications that require repeatable motion over long production cycles.
Heat generated during operation is removed by natural convection, so the housing does not require auxiliary fans or liquid cooling circuits. Rotor position feedback is provided through Hiperface communication, and the optical single-turn encoder delivers 128 signal periods per mechanical revolution for stable speed control and position tracking. The connector can be rotated through 240°, which helps when routing the encoder cable in confined cabinet spaces or around nearby machine structures. An electrically released holding brake provides 10 Nm of static torque to hold vertical axes when power is removed. The motor also has a plain shaft for direct coupling, and the enclosure is rated IP65 to help protect internal parts from dust and water jets in industrial areas.
With a size 061 frame and length designation B, the motor fits medium-power axes while keeping inertia moderate for responsive acceleration. Winding code 0300 identifies the electrical design used for matching drive current and voltage characteristics in this frame. The insulation system is class 155, which supports the thermal demands typically seen in continuous industrial duty. Installation is permitted in ambient temperatures from 0 to 40 °C when the motor has adequate free air circulation around the housing. This combination of frame size, winding selection, and thermal capability makes the unit suitable for general-purpose servo applications that need precise motion without added external cooling hardware.
