Product Description:

The MAC112D-0-ED-4-C/130-A-0/WI517LV/S005 is a motor for analog drives produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for closed-loop motion on axes that use ±10 V speed and torque commands. The motor combines a 112-frame stator, tachogenerator feedback, and encoder support to maintain stable speed and position control in pick-and-place, conveyor, and forming equipment. This arrangement is useful in machines that need repeatable motion without changing to a digital drive platform.

The motor reaches a nominal speed of 3000 rpm, which suits medium-speed spindles and other axes that use typical 4-pole gearbox ratios. Centering in the machine casting is simplified by a 130 mm pilot on the flange. Heat is removed by natural convection, so no auxiliary fan is required. Torque is transmitted through a DIN 6885 keyway, which lets the shaft mate with standard couplings. Incoming power enters through a connector on side A, which keeps cable routing away from the load side. The internal tacho generator supplies 3 V/1000 rpm to the analog controller, and an incremental encoder on the same shaft provides position pulses for feedback. The motor is supplied without a blocking brake, so vertical axes need an external clamp or counterweight when stopped. The tacho generator uses the standard quality grade for this motor type.

The stator uses the ED winding code, which gives electrical values suited to medium-voltage servo amplifiers across the torque range. The motor has length D, which adds active copper for higher continuous power while keeping the same mounting face. An absolute encoder is available as a feedback option when the control system needs single-turn position data immediately after power-up. This can reduce the need for a separate reference run after startup.
