Product Description:

The MAC112A-0-LD-4-C/130-A-0/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for use in industrial automation where rotary motion is commanded by analog drive controllers, supplying regulated torque and speed to positioning, transfer, and packaging machinery axes. Classified as a motor for analog drives, it interfaces directly with legacy Indramat transconductance amplifiers using ±10 V speed commands.

The motor mounts against a flange with a 130 mm centering diameter, allowing precise alignment to gearboxes or load couplings. Heat is removed solely by natural convection, so no external blower or liquid circuit is required. Under rated conditions, the rotor reaches 3000 rpm, a speed that supports mid-range linear feed rates in transfer lines and packaging equipment. Power leads exit through a connector on side A, simplifying cable routing inside cabinets mounted to that face. Speed feedback for the analog drive is generated by a tacho that produces 3 V/1000 rpm, and the standard tacho quality supports consistent voltage linearity. In addition, the feedback configuration permits either tacho feedback with an incremental or absolute encoder, and the installed incremental encoder follows the standard mounting pattern. The motor is supplied without a blocking brake, so external clamping devices are required if shaft holding at power-off is necessary.

The electromagnetic design uses the LD winding code, which matches the current and voltage relationship used for medium-inertia loads. Frame designation begins with a size 112 housing, placing the unit in a medium motor envelope for general automation equipment. The axial stack uses the short motor length A, which helps balance continuous torque and installation footprint in compact machine layouts where mounting depth and coupling clearance are limited.
