Product Description:

The MAC112C-0-HD-4-C/130-A-1/WI5201V is an AC servo motor produced by Bosch Rexroth Indramat for motion axes that rely on precise analog drive regulation. As a member of the MAC AC Servo Motors series, this unit converts drive commands into controlled rotary power for positioning tables, tool changers, and transfer stations in automated lines. It is well suited for machines that need stable closed-loop motion with a compact motor that can be integrated into established analog drive systems.

An integrated holding brake rated at 45 Nm secures the shaft whenever the drive is disabled, allowing vertical loads to remain stationary without external clamps. Installation aligns the housing by a 130 mm centering diameter that simplifies coupling with gearboxes or machine frames. Heat generated by copper losses is removed through natural convection, so the motor can operate without forced-air ducts or liquid jackets. Under nominal excitation, the rotor reaches 2000 rpm, matching speed ranges typical for Indramat analog velocity loops. Power and brake conductors exit through a connector on side A, enabling cable runs along a single machine face and keeping the opposite side clear for mechanical accessories.

The electromagnetic core follows winding code HD, which supports higher continuous torque at moderate drive voltages. Shaft velocity is monitored by a tachogenerator that delivers 3 V/1000 rpm and by an incremental encoder mounted in the standard position, allowing the control card to compare analog speed feedback with high-resolution positional data. The frame is categorized as size 112 with motor length C, a geometry that balances torque density and mass for mid-range axes. Tacho quality is standard, and the combined tacho-plus-encoder feedback matches WI5201V interface requirements for legacy drive cards without additional adapters.
