Product Description

MAC112D-0-ED-4-C/130-A/WI520LX/S018 is a MAC series servo motor from Bosch Rexroth. It is developed for industrial use. MAC motors support several features that make them an ideal choice for demanding applications. The combination of electronic commutation, life-time lubricated bearings, and an IP65 rated housing makes MAC motors maintenance-free. The use of permanent magnets allows construction of motors with low inertia. These motors support tacho feedback developed especially for the series. An additional encoder can be added for position evaluation. Multiple cooling methods are available such as convection cooling and surface cooling. The power and feedback connections comply with IP65 requirements. Speed rating of the MAC112D-0-ED-4-C/130-A/WI520LX/S018 servo motor is 3000 RPM. It is designed for convection cooling and delivers 35 Nm continuous output torque at standstill and 63 Amps continuous current output at standstill. Thermal time constant of the AC servo motor is 120 minutes.

The rotor moment of inertia is 0.0230 kg m2. Torque constant of the motor is 0.620 Nm/A at 20 degrees Celsius. Resistance of the motor windings is 0.070 Ohms at 20 degrees Celsius and the inductance of the windings is 1.3 millihenry. The maximum peak of pulse current is 312 Amps. A heavy duty blocking brake is installed on the motor. Its rated holding torque is 60 Nm. Voltage and current rating of the brake are 24 Volts DC and 1.35 Amps respectively. Release and clamping delay specifications for the brake are 150 and 30 milliseconds respectively. Mass of the blocking brake is approximately 3.5 kilograms. The optimal ambient temperature for MAC motor operation is 0 to 45 degrees Celsius. A black prime coat is applied to the motor housing. Operators can apply an additional paint layer on top.
