Product Description

MAC112D-1-ED-4-C/130-B-1/WI525LV is a Bosch Rexroth servo motor from the MAC series. It is designed with purpose-built tacho feedback technology. Tacho feedback on MAC motors provides speed and position evaluation, it provides real time speed and position measurements to the motor controller. The motor transmits feedback via a dedicated feedback cable connection to the feedback port on the motor. This is an IP65 rated port. Operators must order the feedback cable connector separately. A separate power cable connects the motor to the motor controller. This cable connects to the main power connection on side B of the housing. Operators must order the power cable connector separately. In addition to tacho feedback, an encoder is installed on the motor for position evaluation. Bosch has designed the MAC112D-1-ED-4-C/130-B-1/WI525LV motor for surface cooling.

The motor comes with a factory-installed axial cooling fan. Power requirement of the cooling fan is 230 Volts AC. A standard blocking brake is installed on the motor. Its technical specifications include 45 Nm holding torque, 24 Volts DC nominal voltage, 0.75 Amps nominal current, 0.0036 kg m2 moment of inertia, 70 milliseconds release delay, 30 milliseconds clamping delay and 1.1 kilograms weight. Mechanical specifications for the MAC112D-1-ED-4-C/130-B-1/WI525LV motor include 130 millimeters centering diameter, 612 millimeters motor length, 32 millimeters shaft diameter, and 193 millimeters flange size. Performance specifications for the motor include 3000 RPM nominal speed, 57 Nm continuous standstill torque, 102 Amps continuous standstill current and 0.620 Nm/A torque constant at 20 degrees Celsius. MAC motors are suited to industrial applications that include robotics, machine tools, textile, printing presses and transfer facilities. To ensure error-free installation and operation, only trained personnel should work on the MAC motors.
