Product Description:

The MSM020B-0300-NN-M0-CG0 is a compact synchronous motor produced by Bosch Rexroth Indramat. Within an automation cell, the unit supplies rotary motion with closed-loop feedback to positioning stages, pick-and-place heads, and similar axes. When paired with an IndraDrive controller, it converts electrical energy into torque that can be regulated precisely for small servo axes. The motor is intended for controlled motion rather than simple continuous rotation, so it suits indexing, placement, and small transfer tasks.

In operation, the motor releases heat to ambient air through natural convection, so no auxiliary fan or liquid circuit is required. Power and feedback conductors exit through a short cable tail, which lets the stator fit flush against machine plates while still supporting strain-relieved routing toward the drive. Rotor position is resolved by a multi-turn absolute encoder, allowing the controller to track several mechanical revolutions without homing after power-up. The encoder also retains position information through power cycles within its supported multi-turn range. The mechanical package follows length code B, which balances stack depth with the thermal mass available in this frame. It is part of the MSM IndraDyn S line and uses the mounting dimensions associated with that platform.

The frame designation 020 sets the flange and shaft geometry used with micro gearboxes and timing pulleys in small assembly lines. Because the motor is supplied without a holding brake, static load retention must be provided by drive torque or an external clamp when needed. Winding code 0300 corresponds to the electrical layout used for moderate-speed operation on 24 V or 48 V buses. That electrical combination supports low-voltage servo systems used in compact handling equipment. Because the frame is small, it can be integrated near process tooling or directly on compact mechanisms.
