Product Description

MAC112D-0-HD-4-C/130-A-2/WI520LV/S048 is a Bosch Rexroth servo motor. It belongs to the MAC product line. MAC motors achieve a high degree of reliability due to the brushless design of the motor and the use of life-time lubricated bearings. MAC motors can be used directly within the working area of the machine even under poor environmental conditions such as affects of coolants, soluble oil emulsions, etc. because the motor housing is totally enclosed as per protection category IP65. The motor power and tachofeedback cables as well as the encoder cables are designed to meet IP65 demands. MAC motor temperature is monitored with thermo switches integrated into motor windings and stator housing, which helps to prevent overload damage. As per the product type code, the frame size of the MAC112D-0-HD-4-C/130-A-2/WI520LV/S048 motor is 112 and its frame length is D.

The motor’s speed rating is 1500 RPM. Output torque and current ratings depend on the cooling method. The MAC112D-0-HD-4-C/130-A-2/WI520LV/S048 motor is designed for convection cooling. Its continuous torque at standstill is 38 Nm and the continuous current at standstill is 42 Amps. The rotor moment of inertia is 0.0230 kg m². The torque constant is 1.010 Nm/A at 20 degrees Celsius. The winding resistance is 0.176 Ohms at 20 degrees Celsius. The thermal time constant for the MAC112D-0-HD-4-C/130-A-2/WI520LV/S048 motor is 120 minutes. Bosch has designed the MAC112D-0-HD-4-C/130-A-2/WI520LV/S048 motor with tacho feedback and mounted incremental or absolute encoder. The motor features a 60 Nm blocking brake. Other features include 130 millimeters centering diameter and a power plug on side A. The motor is packed onto a palette or in cartons at the time of delivery. The way motors are packed depends upon the numbers and/or sizes of the motor.
