Product Description:

The MAC112C-0-HD-4-C/130-A-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor intended for analog drives, it delivers controlled torque and speed to positioning axes and continuous-motion machinery used in automated assembly lines, packaging modules, and processing equipment. Its built-in tacho feedback and encoder channels supply velocity and position signals to the drive amplifier so closed-loop regulation can be maintained during operation.

This model is built around a stator frame in motor size 112, which provides space for the laminated iron core and windings while keeping installation dimensions compatible with the series. Shaft alignment with adjoining mechanics is aided by a centering diameter of 130 mm; this interface guides the motor into a housing bore without play. Heat generated in the windings is transferred to ambient air through natural convection, eliminating the need for forced ventilation hardware. The rotor is wound for a nominal speed of 2000 rpm, allowing the drive to support most medium-inertia loads. Power conductors are routed through a connector on side A, which helps support straightforward cable routing on the selected machine face.

The electromagnetic circuit follows the HD winding code, which indicates the copper fill factor and electrical resistance used by associated analog amplifiers. A compact motor length C keeps the mass low while still offering adequate torque reserve for acceleration cycles. For velocity monitoring, the tacho generator outputs 3 V/1000 rpm, and this linear voltage helps the controller detect overspeed conditions quickly. Position-based applications can use the built-in incremental encoder, which is mounted in the standard position and delivers quadrature signals for fine-resolution indexing. The unit operates without a blocking brake, so external holding torque is required when the axis must remain fixed at standstill.
