Product Description:

The MAC112D-0-FD-3-C/130-A-0/S15 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog velocity and position loops, the unit translates the drive’s current signal directly into rotor torque for industrial automation axes. It occupies the D-length frame within the 112 mm stator diameter class and uses a cylindrical mounting face that aligns accurately to host machinery. This layout suits positioning and speed-controlled applications that rely on stable feedback during continuous operation.

The motor size of 112 indicates the stator outside diameter, which affects magnetic cross-section and shaft height for mid-range torque output. Passive dissipation uses natural convection, so heat moves through the housing without forced airflow. A centering diameter of 130 mm guides the housing into the machine pilot bore to maintain concentricity and reduce runout. Under rated excitation, the rotor can reach 2000 rpm, supporting medium-speed spindles and indexing axes. The built-in tacho generator produces 3 V/1000 rpm, giving the analog drive a proportional velocity feedback signal for closed-loop control.

Electrical power is routed through a connector on side A, keeping the cable bundle on the same face as the feedback lead for simpler routing along machine structures. The motor has no blocking brake, so stationary holding torque must be provided by the drive or by an external clamp when power is removed. Winding code FD identifies the wire gauge and turn count, matching the motor to amplifiers that supply the required current and voltage range. The feedback package includes tacho feedback and a second shaft end, allowing an additional measuring element or mechanical load to be attached while the internal tacho maintains standard velocity feedback for analog regulation.
