Product Description:

The MSK101D-0300-NN-M2-LG0-RNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The motor forms a compact, high-torque element in industrial automation, delivering controlled rotation for servo axes in robotics, multi-axis machining centers, packaging lines, and material-handling gantries. Integrated with a matched drive, it supplies tightly regulated torque wherever repeatable positioning and consistent speed profiles are required. Its synchronous design also supports responsive acceleration and smooth low-speed operation when the axis follows frequent start-stop commands.

The motor uses an increased-concentricity design that reduces radial runout at the shaft interface and improves coupling accuracy. A frame size of 101 with length code D sets the stator stack dimensions and rotor inertia. Heat is transferred through natural convection, so installation spaces must allow unobstructed airflow around the housing. The exterior carries an IP65 rating that resists dust and low-pressure water jets in typical plant environments. This protection helps the motor operate reliably in dusty areas and around routine splash exposure. Electrical leads are attached through a left-side power connector, simplifying routing when adjacent devices occupy the right side of the cabinet. The motor has a smooth plain shaft and is supplied without a holding brake, so static holding must be provided by external means or drive torque. Continuous service is approved within an ambient range of 0–40 °C.

The electromagnetic package uses winding code 0300, which aligns coil resistance and inductance with drive outputs while keeping copper temperature below the Class 155 insulation threshold. Rotor position data reaches the controller through the EnDat2.1 serial channel, and its optical scanning mechanism helps maintain low jitter. Inside the feedback head, 2048 signal periods are interpolated to fine incremental counts, and a multiturn absolute register preserves revolution information after power loss, removing the need for reference moves. The feedback system supplies both commutation and position information, allowing the controller to maintain stable motion without a separate reference sensor.
