Product Description:

The MSM030B-0300-NN-M0-CC1 is a synchronous motor in the MSM IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. It converts drive commands into controlled rotary motion for compact servo axes used in material-handling stations and electronic assembly tools. As part of a low-inertia range, the unit responds to rapid start-stop sequences, and its integrated brake lets machines hold position when the control cabinet is unpowered.

Cooling is managed by natural convection; the motor relies solely on surface area and ambient air to remove heat, so no additional blowers are required inside the machine frame. The integrated brake is electrically released, which means it stays mechanically engaged until coil power is applied and allows safe locking during emergencies or power loss. Power and feedback conductors exit through a molded cable tail, simplifying wiring in tight cabinets because no separate connector is needed at the motor flange. Position feedback comes from a multi-turn absolute encoder, providing the controller with an unambiguous shaft position over several mechanical revolutions, which eliminates the need for homing after startup. When energized, the retaining mechanism can withstand up to 1.27 Nm of static torque, helping keep the shaft fixed during tool changes or fixture loading.

With its frame size of 030 and medium axial length code B, the motor occupies little installation space while providing enough active iron for natural cooling. The selected winding code 0300 pairs this mechanical format with voltage and current constants suited to IndraDrive compact inverters, keeping phase currents within standard servo cable ratings. The built-in holding brake supports position retention when external power is removed. This layout suits compact servo axes where limited mounting space and repeatable stopping are important.
