Product Description:

The MSM041B-0300-NN-M0-CH0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MSM IndraDyn S Synchronous Motors series. This compact rotary unit converts drive current into controlled mechanical torque for positioning axes, pick-and-place heads, and package-sealing cams in industrial automation. By pairing with IndraDrive amplifiers, the motor supplies precise speed and position feedback, enabling closed-loop motion in machinery that requires repeatable accuracy while occupying minimal installation space.

At standstill, the rotor can exert 2.40 Nm of continuous torque, giving small indexing tables holding force without thermal overload. Heat generated during operation is removed solely through natural convection, so no external fan or liquid circuit is required. Clearance around the housing supports this passive airflow. Power and feedback lines exit via a factory-terminated cable tail, which simplifies routing through tight cable tracks and removes connector interfaces that could loosen under vibration. Position feedback comes from a multiturn absolute encoder, allowing the controller to know shaft angle over multiple revolutions even after a power cycle. The driving element is a plain shaft, so couplings or pulleys mount directly without a keyway, avoiding backlash introduced by keyed joints.

The motor follows frame size 041 and uses motor length B to achieve a compact overall package length. Because it is supplied without a holding brake, static position retention must be provided by drive torque or an external clamp when needed. A configuration without a shaft seal leaves the front bearing open to ambient air, so the unit should be mounted in clean, dry zones rather than wet processing areas. The motor uses winding code 0300, so matching IndraDrive parameter sets apply the correct current limits and support dynamic response during acceleration and deceleration.
