Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI520LX/S005 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a motor for analog drives that supplies closed-loop rotational power to positioning axes, material-handling stages, and other motion elements inside automated machinery. This model sits in the mid-torque segment of the family. It retains the same flange interface used across companion units, which helps it fit standard machine layouts.

A centering pilot of 130 mm aligns the housing with mating machine frames and helps maintain shaft concentricity. The rotor can maintain rated velocity at 3000 rpm, a speed chosen to match common gearbox ratios and drive tuning profiles. Heat produced at that operating point leaves the frame through natural convection, eliminating the need for external blowers or coolant circuits. Output torque is transferred through a shaft machined with a DIN 6885 keyway, giving a standardized fit for couplings and sprockets. The integrated tacho generator issues a feedback signal of 3 V/1000 rpm, enabling analog velocity regulation, while an auxiliary encoder channel supports digital position loops. Electrical performance is set by the ED winding, which matches the compatible drive module and current range, and the three-phase power leads exit through a molded connector at the stator frame.

Speed and position are supervised by an incremental encoder mounted in the feedback compartment, and its pulses align with the tacho signal for dual-channel monitoring. Because the model is built to motor length C, inertia remains moderate, which helps rapid starts and stops without excessive overshoot. There is no mechanical holding action because the blocking brake is absent, so vertical axes must use external clamping or another holding method. Final terminations are simplified by the connector on side A, which groups power and earth contacts away from nearby machine obstacles and helps keep cable bends within allowable radii.
