Product Description:

The MAC090B-0-PD-2-C/110-A-1/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat and included in the MAC AC Servo Motors series. It is intended for analog drive systems. The motor converts commanded current into controlled rotary motion for positioning and speed control tasks throughout automated machinery and material-handling stations. Its servo design suits motion axes that require repeatable starts, stable speed regulation, and dependable operation during routine machine cycles.

The centering diameter measures 110 mm, allowing the housing to locate accurately in machined mounting bores and maintain shaft alignment. Heat is removed by natural convection, so no external blower or coolant circuit is required. This cooling method keeps installation simple and avoids added airflow hardware around the motor body. A built-in blocking brake secures the shaft whenever power is removed, helping prevent load drift on vertical or suspended axes. Under rated excitation, the rotor reaches 1500 rpm, providing a balance between torque production and system inertia for medium-speed positioning. The integrated tachogenerator supplies 3 V/1000 rpm, feeding the analog controller with real-time velocity data for closed-loop regulation.

The feedback scheme uses tacho feedback, delivering speed information without relying on digital encoders or high-resolution resolvers. Power conductors exit through a connector on side A, which helps route cables toward the drive cabinet when several motors are installed in the same area. The stator uses the PD winding code, which matches resistance and inductance values to analog amplifier current limits and dynamic response goals. The motor also uses standard tacho quality, indicating the accuracy class of the tachogenerator during acceleration, deceleration, and steady-state load changes.
