Product Description:

The MAC090B-0-PD-2-C/110-B-1/S01 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for closed-loop positioning with analog drive controllers, it converts commanded current into precise shaft rotation for conveyor sections, positioning tables, and tool axes. The motor works with analog control systems that rely on feedback to regulate speed during repeated starts, stops, and position changes. Its flange follows MAC frame size 090 dimensions, so it fits machine layouts built around this housing size. This makes it suitable for machinery that needs steady motion response without a digital network at the motor.

The centering pilot on the front flange measures 110 mm, providing a reference surface that aligns the housing with the machine frame. Heat is removed by natural convection, so airflow around the exterior must remain unobstructed during continuous operation. Rotor speed under nominal conditions reaches 1500 rpm, which suits applications that need stable servo motion without very high shaft speed. Speed feedback comes from the integrated tacho feedback, which supplies a proportional signal to the analog drive. Power is routed through a connector on side B, keeping the cable exit away from the driven shaft and helping cable routing in compact machine spaces.

A standard blocking brake is fitted, so the axis can hold position when the amplifier is disabled without external clamps. The tacho generator delivers 3 V/1000 rpm, letting the controller derive actual speed from a simple voltage signal. Stator windings follow code PD, matching the electrical values used by classic MAC power stages. This configuration supports stable operation with analog drive modules that depend on proportional speed feedback and consistent winding behavior. The combination of brake, tacho output, and winding selection is useful in older automation systems that still use established analog servo architecture.
