Product Description:

The MSM040B-0300-NN-C0-CG0 is a synchronous motor manufactured by Bosch Rexroth Indramat and assigned to the MSM IndraDyn S Synchronous Motors series. Within automated assembly cells and material-handling lines, it converts regulated drive current into rotary motion for lightweight positioning axes, grippers, and auxiliary conveyors. Compact dimensions, permanent-magnet excitation, and close pairing with IndraDrive controllers allow the unit to deliver precise speed and torque profiles that support repeatable process cycles in confined machine spaces. Its compact form suits installations where several servo axes are grouped on short centers and where predictable response is needed for repetitive starts, stops, and direction changes.

Heat removal relies on natural convection, so the motor's continuous rating depends on unobstructed airflow over the housing rather than fan assistance. A factory-installed cable tail integrates power, feedback, and ground conductors, which simplifies routing through drag chains and reduces the number of enclosure terminations. Axis feedback comes from an incremental encoder that supplies quadrature signals for closed-loop speed and position control. Because the rotor is supplied without a holding brake, static load retention must be provided by external clamps or drive torque when power is off. The frame size of 040 corresponds to a 40 mm square mounting flange that helps place multiple axes close together.

Ambient temperature affects the available continuous torque, so airflow around the housing should remain unobstructed during operation. With body length B, the stator stack is longer than the A variant, providing higher continuous torque without changing shaft height or bolt pattern. The stator uses winding code 0300, which sets the resistance and inductance values used by compatible drives. This combination keeps the mechanical envelope compact while supporting steady output on axes that run frequent motion cycles.
