Product Description:

Bosch Rexroth Indramat manufactures the MAC112B-0-PD-3-C/180-A-2/S019 within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive-amplifier commands into controlled rotary motion for positioning tables, gantries, and other industrial axes. The model combines tacho feedback with a second shaft end so the connected controller can read real-time speed while an external encoder, brake, or coupling can share the opposite side of the rotor. These features let the unit execute precise moves and hold loads in mid-cycle when required by the machine program.

A heavy-duty blocking brake is integrated at the non-drive end, and its holding torque of 60 Nm keeps vertical or high-inertia loads from drifting when the amplifier is disabled. The motor seats against mounting flanges through a 180 mm centering diameter, which aligns the stator housing without relying on bolt shear. Heat generated in the stator windings is released by natural convection, eliminating the need for external blowers and simplifying enclosure layouts. The electromagnetic circuit uses the PD winding code, matching the motor to amplifiers that can supply the corresponding voltage and current profile during dynamic duty cycles.

Dynamic performance centers on a nominal speed of 1500 rpm, a rating that pairs with the tachogenerator output of 3 V/1000 rpm to give the analog drive a proportional velocity signal. Power conductors reach the stator through a connector on side A, keeping cable routing on the same face as most MAC112 service ports. Frame attributes include motor size 112 and motor length B, dimensions that balance torque potential against installation depth inside compact machine frames. Standard tacho quality supports consistent feedback linearity, and the second shaft end permits the mounting of additional sensors or mechanical brakes without altering the primary coupling.
