Product Description:

The MAC090B-0-PD-1-B/110-A-0 is a three-phase AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Engineered for motion systems that rely on analog velocity and current loops, the unit pairs with MAC servo amplifiers to deliver precise positioning and stable speed control. It converts electrical setpoints into regulated mechanical output for assembly equipment, indexing tables, and other industrial axes that require consistent torque delivery. Integrated feedback allows the connected drive to monitor rotor motion continuously during operation.

This model uses a centering pilot of 110 mm, allowing repeatable alignment with gearboxes or flange mounts. Heat is dissipated through natural convection, so no external blower or coolant interface is required. Rotor position is detected by incremental encoder feedback, giving differential square-wave signals for velocity and position loops. The rated base speed is 1500 rpm. For drive-side speed regulation, a built-in tacho generator produces 3 V/1000 rpm, providing analog velocity feedback without an additional sensor. This feedback arrangement lets the controller track speed and position during continuous motion.

Because the motor has no blocking brake, any holding torque during power-off must be supplied by external clamps or drive torque. This arrangement favors horizontal transport stages where gravity does not impose a back-driving load. The power leads exit through a connector on side A, keeping motor cabling on the same face as most MAC feedback plugs and easing panel layout. Its classification as a motor for analog drives confirms compatibility with MAC drive cards that regulate current and speed through ±10 V interfaces. Winding code PD indicates the stator resistance and inductance set used with the matching amplifier current range.
