Product Description

MAC112C-0-ED-3-C/130-B-1/S005 is a servo motor. It is a product of Bosch Rexroth. MAC motors are designed with tacho feedback technology specially developed for this product line. The motor has a robust IP65 rated housing. This housing is completely dustproof. In addition, the motor housing provides protection from water directed at the motor from low-pressure jets. With this robust ingress protection, MAC motors can be deployed in adverse operating conditions. A brushless design and use of bearings that don?t require lubrication enables maintenance-free operation. The MAC112C-0-ED-3-C/130-B-1/S005 motor supports convection cooling. The benefit of this cooling method is lower operating expense as cooling fans with additional power requirements are not used. The downside of convection cooling is comparatively lower output torque and current. Rated output torque and current of the motor at standstill are 24 Nm and 57 Amps respectively.

Moment of inertia of the motor rotor is 0.0170 kg m2. The torque constant of the AC servo motor is 0.470 Nm/A at 20 degrees Celsius. Resistance of the motor windings is 0.060 Ohms at 20 degrees Celsius. Inductance of the motor windings is 1 millihenry. The maximum peak of pulse current is 312 Amps. Thermal time constant of the motor is 100 minutes. Centering diameter of the MAC112C-0-ED-3-C/130-B-1/S005 motor is 130 millimeters. MAC112 series motors with 180 millimeter centering are available. A standard holding brake is installed on the motor. Its rated holding torque is 45 Nm. Holding brakes with higher are available if required. The motor shaft includes a keyway. MAC motors with smooth shafts are also available. Weight of the servo motor is 48 kilograms, and weight of the optional holding brake is 1.1 kilograms.
