Product Description:

The MSM031C-0300-NN-M5-ML1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSM IndraDyn S Synchronous Motors series. Designed for closed-loop drive systems, the unit converts electrical commands from an IndraDrive controller into precise rotary motion for conveyors, pick-and-place axes, and compact packaging machinery. Its compact frame supports installation in decentralized cabinets where small, efficient actuation elements are required in industrial automation cells. It is suited to applications that require accurate motion from a small motor package. This layout also helps when available mounting space is limited and cable runs must stay short.

At standstill, the rotor can deliver a continuous torque of 1.30 Nm, allowing stable positioning without thermal overload during the rated duty cycle. Heat is removed only by natural convection, so surrounding airflow must carry heat away from the housing during operation. The motor uses an electrically released brake; spring force holds the shaft and DC voltage opens the brake during motion. The motor has a frame size of 031, and its electromagnetic characteristics follow winding code 0300. That combination supports compact servo axes that need steady torque output without external cooling hardware.

For stop-state safety and vertical-axis retention, the integral brake supplies a static torque of 1.27 Nm, which is intended to hold the load when the drive is disabled. Because a holding brake is included, the axis can remain in position without a separate external clamp. The housing uses length code C, which gives the motor a longer body without changing the mounting flange pattern. The brake provides static torque for load holding when the motor is not turning. This holding function is useful during dwell periods, controlled stops, and other conditions where the shaft must remain stationary.
