Product Description

MAC112D-0-FD-1-B/130-A-1/J625/S05 is a MAC series Bosch Rexroth servo motor. Mechanical specifications for the motor include 193 millimeters flange, 130 millimeters centering diameter, 59 kilograms weight, 32 millimeters shaft diameter and 535 millimeters motor length. The motor supports convection cooling. Its performance specifications include 38 Nm continuous torque at standstill, 56 Amps continuous current at standstill, 0.023 kg m2 rotor moment of inertia, 120 minutes thermal time constant and 0.76 Nm/A torque constant at 20 degrees Celsius. Resistance of the motor windings is 0.110 Ohms at 20 degrees Celsius. Inductance of the motor windings is 1.8 millihenry. The motor shaft includes a keyway and complies with DIN 6885-1. A standard holding brake is installed on the MAC112D-0-FD-1-B/130-A-1/J625/S05 servo motor. Its holding torque rating is 45 Nm. Voltage rating of the brake is 24 Volts DC and the current draw is 0.75 Amps.

Moment of inertia of the brake is 0.0036 kg m2. Release delay of the brake is 70 milliseconds and the clamping delay is 30 milliseconds. The mass of the motor blocking brake is 1.1 kilograms. This brake is an electrically-released brake: after clamping down on the shaft, it releases the shaft after receiving the DC release signal from the motor controller. The permissible ambient temperature for rated output is 0 to 45 degrees Celsius. The maximum installation elevation is 1000 meters above sea level. Protection category of the motor housing and cable connections is IP65. Insulation classification of MAC motors is F. The permissible temperature for motor transportation and storage is -20 to 80 degrees Celsius. A black prime coat applied to the motor housing provides corrosion resistance. Only trained personnel should handle MAC motors.
