Product Description:

The MAC071B-0-PS-4-C/095-A-2/WI520LV/S001 is an AC servo motor engineered by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Supplied as a motor for analog drives, it converts commanded input signals into controlled torque for indexing tables and other automation duties. Integrated tachometer and encoder feedback allow the paired drive to monitor shaft motion without external sensors, and the flange-mounted housing supports direct installation in machine structures. Its integrated feedback package also keeps the motor compact because no separate external measurement device is required.

Mechanical interface dimensions follow the MAC family coding. The motor uses size code 071 with length B, giving it a compact housing with a longer magnetic stack for higher continuous output. A centering pilot of 95 mm aligns the flange with gearboxes or adapter plates, and torque is transmitted through a DIN 6885 keyway machined into the shaft. Heat is removed by natural convection, so no external blower is required. Under rated conditions, the motor reaches 4000 rpm. When the axis must remain fixed, the integrated brake can hold up to 6.5 Nm to resist back-driving during power loss.

Power and feedback wiring terminate at a connector on side A, which helps with cable routing in tight housings. The integrated tachogenerator produces 1.5 V/1000 rpm for analog velocity feedback, and winding code PS matches the electrical characteristics expected by compatible MAC series amplifiers. The motor is supplied with a blocking brake, so it can hold the shaft during downtime when mains power is removed. Keeping the connection point on one side can also reduce cable crowding near adjacent machine components, especially in compact axis layouts.
