Product Description:

Bosch Rexroth Indramat’s MAC112B-0-PD-4-C/180-A-0/W1511LV/S011 belongs to the MAC AC Servo Motors series. It is intended for analog drive controllers that require accurate speed and position regulation during automated motion tasks. In machine tools, packaging axes, and material-handling gantries, the motor converts drive current into regulated rotary motion so connected mechanisms can follow programmed profiles with minimal deviation and stable response under changing loads.

The rotor seats against a centering flange that measures 180 mm in diameter, allowing the housing to align consistently with gearboxes, mounting brackets, or machine faces. Its stator uses the PD winding code, which sets the phase resistance and inductance expected by the connected amplifier during torque production. Heat produced in the copper is carried away by natural convection, so no external blower or liquid jacket is required and the installation stays mechanically simple. Under rated conditions, the shaft reaches 1500 rpm, a speed that suits common reduction ratios for linear carriages, indexing axes, or spindle drives. For velocity feedback, an internal tacho generator outputs 3 V/1000 rpm, giving the drive a proportional signal for closed-loop speed control.

The unit is supplied without a blocking brake, so any holding function during downtime must be provided by the machine or by drive-generated torque when appropriate. Torque is delivered through a DIN 6885 keyway, which secures couplings or pulleys while maintaining shaft alignment during motion transmission. The motor uses length code B, and frame size 112 places it in the matching stator diameter family used for this series. Power and encoder lines exit through a connector on side A, which can simplify cable routing where the energy chain or cabinet entry is arranged on that side of the machine.
