Product Description:

Bosch Rexroth Indramat manufactures the MAC112B-0-PD-4-C/130-A-2 within the MAC AC Servo Motors series. Designed for analog drive systems, this AC servo motor transforms controlled current into precise rotary motion for axes in assembly machines, packaging lines, and material-handling stages. Its mechanical interface follows a metric mounting pattern, allowing direct coupling to gear reducers or belt transmissions without additional adapter plates. Integrated thermal pathways support passive cooling, keeping overall maintenance low in closed cabinets.

The motor is equipped with a heavy-duty blocking brake that locks the shaft when power is removed. Its holding capability is rated at 60 Nm, allowing vertical axes to maintain load position during downtime. A centering pilot of 130 mm aligns the housing in precision-machined mounting faces and helps keep radial runout low. Heat generated in the stator is released by natural convection, so no additional blower or liquid circuit is required. At rated excitation, the rotor turns at 1500 rpm, a moderate base speed that suits gear reductions common in transfer lines and gantries. Its tacho quality is standard, ensuring repeatable readings for conventional analog loops.

Electrical power reaches the stator through a connector on side A, keeping cabling on the same face as the brake release circuit and simplifying routing. The integral tachogenerator supplies a feedback signal of 3 V/1000 rpm, and the motor can also be fitted with an incremental or absolute encoder so the drive can use the required closed-loop method. Winding code PD identifies the copper fill and turns per phase, matching the motor to analog amplifiers with the corresponding voltage constant. The frame code 112 and length code B indicate the core dimensions and rotor inertia for medium-power applications.
