MSM031C-0300-NN-M5-ML0

The Bosch Rexroth Indramat MSM031C-0300-NN-M5-ML0 from the MSM IndraDyn S Synchronous Motors series is a precision-engineered Synchronous Motor designed for compact installations. It features a Motor Size 031 frame with a Motor Length C housing, while the Winding Code 0300 stator delivers a Continuous Torque at Standstill of 1.30 Nm. Electrical integration is streamlined via a Cable Tail connection and a high-resolution Multiturn, Absolute encoder. The rotor shaft is configured With Keyway, Without Sealing Ring, and the design omits a holding brake to minimise inertia.

Operating under Natural convection cooling, the motor sustains a nominal speed of 3000 rpm and a maximum speed of 5000 rpm, ensuring dynamic response across a broad range. The encoder draws a Maximum Current Consumption of 70 mA and supports speeds up to 6000 rpm with Encoder Resolution of 20 + 16 bit. Winding inductance measures 10.600 mH, while the unit is rated for a Maximum Current of 7.70 A and a Maximum Torque of 3.80 Nm during peak demands. Protection meets IP54 standards with a pollution degree of 2 per EN50178, and overvoltage category III in line with IEC60664-1.

Designed for global deployment, the MSM031C-0300-NN-M5-ML0 withstands transport and storage in the Climatic Category 2K3 as defined by IEC721, and operates safely between –20 °C and +80 °C. At 20 °C, the motor’s Torque Constant of 0.51 Nm/A and a Voltage Constant of 30.6 V/min⁻¹ enable precise torque-to-current conversion. With an overall mass of 1.2 kg and leakage capacitance of 1.4 nF, this robust motor carries a one-year warranty for dependable performance in automation, packaging, and robotics applications.
