Product Description:

The MAC090B-0-PD-4-C/110-A-2/WI520LV/S018 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Engineered for installation in analog drive systems, the unit converts proportional voltage commands into precise shaft torque and speed so that older control architectures can maintain closed-loop automation. Its electromechanical design supports continuous cyclic duty on machining centers, packaging lines, and material-handling stations that demand repeatable motion without digital network control. This makes the motor suitable for equipment that depends on stable response during repeated starts, stops, and dwell periods.

A heavy-duty blocking brake is fitted to secure the shaft whenever power is removed, making the motor useful for vertical or indexing loads. The centering pilot measures 110 mm, allowing rigid alignment to gearboxes or flange plates. Heat dissipates through natural convection, eliminating auxiliary fans and simplifying enclosure layout. Under rated excitation, the electromagnetic stack reaches a nominal speed of 1500 rpm, balancing torque output with moderate inertial loads. Power and protective earth conductors terminate on a plug located on side A, which can simplify cable routing when the connector side faces the cabinet. The stator uses winding code PD, matching the voltage constant and current rating used by MAC analog amplifiers.

Speed feedback is provided by tachometer feedback and an incremental or absolute encoder interface, allowing the drive to process both analog speed information and encoder signals from the same motor. For position loops, an integrated incremental encoder with standard mounting delivers phase-shifted pulse trains that the controller can multiply for higher count resolution. The tacho generator produces 3 V/1000 rpm, giving a linear voltage proportional to shaft speed and supporting analog velocity regulation without digital scaling. Tacho quality is standard, which is suitable for general-purpose motion tasks that do not require enhanced linearity. This feedback arrangement helps the drive maintain smooth speed regulation during changing loads and routine positioning moves.
