Product Description

MAC112D-0-ED-4-B/130-A-0/WI524/S05 is a Bosch Rexroth servo motor. It belongs to the MAC product line. MAC112 series AC servo motors are available with a special winding design that achieves a high degree of smooth run. It is particularly suited to applications involving grinding machines and precision lathes. General applications of MAC motors include textile machines, printing presses, and packaging machinery. With convection cooling, the continuous standstill torque of the MAC112D-0-ED-4-B/130-A-0/WI524/S05 motor is 35 Nm and the continuous standstill current is 63 Amps. The thermal time constant with convection cooling is 120 minutes. Moment of inertia of the motor rotor is 0.0230 kg m2. The torque constant at 20 degrees Celsius is 0.620 Nm/A. Resistance of the motor windings at 20 degrees Celsius is 0.070 Ohms. Inductance of the motor windings is 1.3 millihenry. The maximum peak of pulse current is 312 Amps.

Weight of the motor is 59 kilograms. Its centering diameter is 130 millimeters. Length of the motor housing is 535 millimeters. Size of the flange on the motor is 193 millimeters. The motor has a shaft with keyway. Diameter of the shaft is 32 millimeters. Shafts with keyways are ideal for form-fitting shaft-hub connections. The MAC112D-0-ED-4-B/130-A-0/WI524/S05 motor supports tacho feedback for position and speed evaluation. It is also equipped with a mounted encoder for position evaluation. Rated output is only possible when the temperature is between 0 and 45 degrees Celsius and when the site elevation is between 0 and 1000 meter. The output derates if either the temperature or elevation are outside specified limits. Bosch permits derated operation of MAC motors at altitudes between 1000 and 5000 meters and at temperatures between 45 and 55 degrees Celsius.
