Product Description:

The MAC112C-0-HD-4-C/130-A-2/WI520LX/S018 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it is used with older current-controlled amplifiers. It supplies precise torque and speed profiles for indexing tables, gantries, and general-purpose motion axes in industrial automation. This arrangement supports motion tasks that still depend on analog command and feedback loops.

The rotor seats against a 130 mm centering diameter, allowing accurate concentric mounting that minimizes shaft runout in coupled equipment. Heat from the stator windings is removed by natural convection, so no external blower or liquid circuit is necessary. The motor reaches a nominal operating speed of 2000 rpm, a value that balances dynamic response with bearing life for medium-inertia loads. The winding arrangement supports a continuous torque curve and pairs with a braking element capable of delivering 60 Nm of holding force during power-off or emergency stops. Electrical power is routed through a connector on side A, keeping motor cabling on the same face as feedback leads and enabling compact routing in tight machine frames.

A heavy-duty blocking brake is integrated to lock the shaft whenever drive current is absent, preventing gravity-induced motion on vertical axes. Speed supervision comes from a tachogenerator that produces 3 V/1000 rpm, and this tacho signal feeds legacy controllers that require an analog velocity loop. An incremental encoder with standard mounting supplies position data, and the feedback harness supports tacho feedback as well as absolute formats for hybrid control strategies. The mechanical envelope follows motor size 112 dimensions, while the stator stack corresponds to motor length C, giving additional core depth for higher continuous current without exceeding frame width.
