Product Description:

The MSM030C-0300-NN-M0-0G1 is a three-phase servo axis built by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. As a compact synchronous motor, it converts drive current from an IndraDrive controller into precise rotary motion for positioning tables, pick-and-place modules, and other automated stations on the plant floor. By integrating a feedback encoder and a holding brake within the housing, the unit delivers closed-loop speed control and static holding capability required in industrial automation cells.

Inside the stator, winding code 0300 indicates resistance and inductance values chosen for moderate continuous current and rapid torque buildup. Position feedback is furnished by a multi-turn absolute encoder, so the controller always knows the shaft angle even after power cycling, eliminating the need for homing. The integrated brake is electrically released; spring force locks the shaft when power is removed and frees it only when the drive energizes the coil. This brake supplies 1.27 Nm of holding torque, which is suitable for securing lightweight vertical loads at a standstill. Heat is dissipated solely through natural convection, so no external fan or liquid circuit is required, and the motor should be mounted with enough surrounding space for unobstructed airflow around the frame.

The mechanical format uses size code 030 with length designation C, yielding a short overall body that fits confined spaces on delta robots and gantry axes. Because a holding brake is present, the motor can keep a load stationary when power is removed without requiring an external clamping device for basic static retention. The rotor and stator arrangement forms a synchronous motor, so torque is available from zero speed with minimal position error under servo control. The compact housing also suits cyclical start-stop duty where low inertia and repeatable positioning are important.
