Product Description:

The MSM040B-0300-NN-M0-CC0 is a compact servo-grade motor produced by Bosch Rexroth Indramat and assigned to the MSM IndraDyn S Synchronous Motors series. Intended for pick-and-place axes, light gantries, and small handling modules, the unit converts drive current into precise rotary motion that can be tightly coordinated with PLC motion profiles. Its size makes it suitable for compact axes where short moves, repeatable positioning, and low moving mass are important. Its compact format also suits stations where axis spacing is limited and moving components must remain light for fast cycle times.

Heat is dissipated through natural convection, so no fan or liquid circuit is required as long as ambient air can circulate freely around the housing. All power, feedback, and safety conductors exit through a factory-installed cable tail, which reduces installation depth and avoids the bulk of rear connectors. Rotor position is tracked by a multiturn encoder that stores several mechanical revolutions, allowing the controller to resume motion sequences immediately after power is restored. The motor is supplied without a holding brake, which helps reduce mass and inertia when vertical load retention is not required. It is a synchronous motor, so it relies on sinusoidal phase currents that remain in step with the permanent-magnet field and help minimize torque ripple at low speed.

The motor uses the MSM family’s 040 frame code, which provides a 40 mm square mounting flange and a standardized pilot diameter. The electromagnetic circuit uses winding code 0300, and this winding matches low-voltage IndraDrive controllers that provide the required current density for high peak speed. The motor has a B motor length, which offers a middle option between the shorter A and longer C variants while balancing torque output and overall envelope size. Because the feedback device supplies an absolute position reference, no homing switch is needed, and axis initialization time is reduced in multi-shift automation lines.
