Product Description

MSM031B-0300-NN-M5-MH0 is a Bosch Rexroth servo motor. It is designed for industrial applications. The motor is equipped with a 20-bit multiturn encoder. This high-resolution encoder provides accurate feedback about motor speed and position. The controller connected to the motor uses motor feedback to make suitable adjustments to its output. This is an example of closed loop control which uses feedback for precise and accurate control of motor speed and position. The motor has a smooth shaft without a shaft seal. Protection rating of the motor shaft is IP40. The motor housing belongs to IP54 protection class. Bosch has designed the servo motor for convection cooling. The recommended ambient temperature for rated output is 0 to 40 degrees Celsius. The main shaft is smooth and does not feature a shaft seal.

MSM motors support optional holding brakes. However, the MSM031B-0300-NN-M5-MH0 motor is without a brake. The main power connection on the motor has a M17 circular connector. Rated power output of the motor is 0.2 kilowatts. The continuous torque at standstill is 0.64 Nm. Peak torque output of the motor is 1.91 Nm and the peak current output is 4.9 Amps. Resistance of the windings on the MSM031B-0300-NN-M5-MH0 motor is 6.10 Ohms at 20 degrees Celsius. The inductance of the motor windings is 14.7 millihenry. The motor has four pole pairs. Moment of inertia of the motor rotor is 0.000014 kg m2. Bosch recommends wire with 0.75 mm2 cross section for motor power. Peak speed of the servo motor is 5000 RPM. Its weight is 0.82 kilograms. Self-cooling of the motor should not be prevented due to the installation situation. Failure to maintain ambient temperature within prescribed limits can lead to malfunction.
