Product Description:

The MSM040B-0300-NN-C0-CG1 synchronous motor belongs to the MSM IndraDyn S Synchronous Motors series produced by Bosch Rexroth Indramat. It is intended for servo axes in compact machinery, where electrical drive commands must be converted into accurate rotary motion for positioning, indexing, and cyclic feed tasks. When paired with IndraDrive servo amplifiers, the motor responds with low delay so the control loop can maintain stable speed regulation and repeatable positioning in small assembly stations, compact conveyors, and packaging modules. Its compact format helps it fit machines where available mounting space is limited but controlled motion is still required throughout frequent start-stop cycles.

The motor uses an electrically released brake, so the shaft remains locked until current disengages the brake mechanism. Cooling is handled by natural convection, which removes heat without a separate fan and keeps the installation simpler. Power and feedback conductors exit through a factory-installed cable tail, allowing direct routing to the cabinet and reducing the need for extra connection hardware. Position data is supplied by an incremental encoder, which sends pulse signals that the drive uses for speed and position evaluation. At standstill, the brake provides 2.45 Nm of holding torque to resist back-driving on axes that must stay in place when drive power is removed.

The motor uses frame size 040 with length code B, giving it a compact body with a medium stack depth for lightweight tooling and small servo axes. Its winding code 0300 matches the electrical values expected by compatible low-voltage drive settings, helping the amplifier apply current in a controlled way during acceleration and steady operation. This combination suits applications that need responsive starts, accurate indexing, and reliable holding at rest without adding a large motor package. The overall layout is intended for compact machine sections where cable space and motor envelope are limited.
