Product Description:

The MAC112A-0-VD-2-C/130-A-0 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for analog drives, it converts drive controller commands into controlled mechanical motion for positioning and feed axes in automated machinery. In typical service, it is paired with an external amplifier that closes the velocity loop and corrects for load changes during operation. That arrangement suits transfer systems, feed drives, and other axes that require predictable rotary response from an analog servo platform.

To fit precisely on machinery frames, the motor shaft seats against a centering flange of 130 mm. Its rotor is optimized for a nominal speed of 2000 rpm, so analog drives can maintain steady motion without entering field-weakening ranges. Heat produced under load is removed by natural convection, which eliminates the need for external blowers and supports simple passive cooling. Rotor position and speed are reported through standard tacho feedback, enabling analog controllers to regulate velocity with a proportional voltage signal. Because there is no blocking brake, holding torque must be supplied by the drive or an external mechanical lock when the axis is idle.

The tacho generator supplies a feedback signal of 3 V/1000 rpm, which matches older analog drive cards. Power conductors enter through a connector on side A, allowing cable runs to follow the motor housing and reducing bend stress. This connection orientation can simplify routing when the motor is mounted beside machine guards or within narrow frame sections. With a frame code of 112, the stator diameter matches other units in the series, and the compact A stack length helps keep inertia low for responsive acceleration. Winding set VD indicates the electrical resistance and inductance values used by matched analog amplifiers.
