Product Description

MAC112D-0-ED-2HC/130-B-2/S018 is a Bosch Rexroth servo motor. It is part of the MAC product line. MAC AC servo motors are made with special permanent magnets. Use of these magnets allows construction of low inertia motors. MAC motors have a brushless design and use electronic commutation which uses solid state circuits for commutation, reduces maintenance requirements and improves safety and reliability. MAC motors have IP65 rated housings and IP65 rated cable connections. Strong ingress protection improves motor reliability and allows motor use in adverse operating conditions. MAC motors require 0 to 45 degrees Celsius ambient temperature and 0 to 1000 meters site elevation for rated output. Motor operation outside these limits leads to output derating and should be avoided. The main shaft on the MAC112D-0-ED-2HC/130-B-2/S018 motor has a keyway and complies with DIN 6885-1 requirements.

Diameter of the motor shaft is 32 millimeters. A heavy-duty blocking brake installed on the motor provides additional safety against unintentional motor shaft rotation. Holding torque rating of the brake is 60 Nm. The brake operates at 24 Volts DC and draws 1.35 Amps. Release delay of the brake is 150 milliseconds and its clamping delay is 30 milliseconds. Approximate weight of the brake is 3.5 kilograms. Nominal speed rating of the motor is 3000 RPM. As it is designed for convection cooling, the rated torque at standstill is 35 Nm and the rated current at standstill is 63 Amps. Moment of inertia of the main rotor is 0.0230 kg m2. Torque constant of the motor at 20 degrees Celsius is 0.620 Nm/A. The winding resistance is 0.070 Ohms at 20 degrees Celsius and the windings inductance is 1.3 millihenry.
