Product Description:

The MAC112D-0-GD-4-C/130-B-1/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves as a drive element for positioning and speed-control tasks in industrial automation. The motor converts regulated electrical current into controlled rotary motion for machine axes in packaging equipment, production systems, and material-handling machinery. Its integrated feedback components provide the signals needed for precise velocity and position control under changing mechanical loads.

The motor has a frame size of 112 and a centering diameter of 130 mm, allowing it to seat accurately in a correspondingly sized mounting flange. Stator stack length code D indicates the magnetic core depth and supports the continuous torque capability required for mid-range loads. An installed blocking brake provides a holding torque of 45 Nm, allowing vertical or suspended loads to remain stationary when motor power is removed. Heat is dissipated through natural convection, so the housing does not require a forced-air blower or liquid cooling circuit. Adequate clearance around the motor allows rising air to carry heat away from the external housing surfaces during operation.

Rotor position and speed are reported through a feedback package that combines tacho feedback with an incremental encoder. The tacho signal provides continuous velocity information, while the encoder supplies digital counts for position tracking by the connected control system. The incremental encoder is secured with standard mounting hardware, and the tacho signal quality follows the standard grade used for this motor series. The stator uses winding set GD, which matches the electrical characteristics expected by compatible analog servo amplifiers. Power conductors terminate through a connector on side B of the housing, providing a fixed cable-routing direction for installation. Separating the power connection from the feedback and brake wiring helps reduce interference between high-current conductors and low-level signal lines. The external amplifier regulates motor current in response to command and feedback signals, while the integrated transducers report actual shaft movement throughout each operating cycle.
