Product Description:

The MSM030C-0300-NN-C0-CC1 is a synchronous motor manufactured by Bosch Rexroth Indramat and belongs to the MSM IndraDyn S Synchronous Motors series. Classified as a rotating actuator for servo duty, it converts bus-supplied three-phase energy into controlled torque and speed for automated axes. The unit targets pick-and-place stations, compact gantries, and auxiliary packaging drives where limited mounting depth and consistent positioning repeatability are required. In those applications, it functions as the controlled rotary element for short moves, synchronized indexing, and repeatable cycle timing.

The motor’s braking arrangement uses an electrically released design, so spring pressure clamps the shaft until the control system energizes the brake coil to disengage it. Because a dedicated holding brake is present, suspended loads remain secure during an emergency stop or power loss, and the mechanism can exert 1.27 Nm of static torque to lock the rotor. Heat generated in the stator dissipates by natural convection, eliminating the need for fans while requiring installation in free-air zones within the rated ambient range. All power, encoder, and brake conductors exit through a molded cable tail, which reduces connector count and shields the leads from oil spray and vibration common in small machinery enclosures.

The motor has size code 030 and length code C, a pairing that produces a short rotor stack with low inertia so rapid acceleration profiles can be commanded without oversizing the drive. The motor uses winding code 0300, which gives fixed resistance and inductance values that match IndraDrive amplifier current ratings and support stable servo tuning. Rotor position feedback comes from an incremental encoder that outputs quadrature channels plus a reference pulse, allowing the controller to re-establish the mechanical zero after each power cycle. The low-inertia layout and encoder feedback suit compact axes that make frequent starts, stops, and short indexing moves across repeated machine cycles.
