Product Description:

The MAC090B-0-PD-1-B/110-A-0/J01250 is an AC servo motor from the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is engineered to interface with analog drive amplifiers, providing precise velocity and torque output for automated machinery such as indexing tables, material-handling gantries, and machining axes. Within an automation cell, the motor converts the drive’s command voltage into mechanical rotation, enabling coordinated multi-axis motion without internal control electronics.

This unit has a centering pilot of 110 mm, a dimension that matches flange recesses and keeps shaft alignment accurate during assembly. Its rated operating speed is 1500 rpm, which is the operating point at which rated torque and frequency are achieved. Heat produced in the stator is carried away by natural convection, so no auxiliary blower or liquid circuit is required. Rotor position is returned to the amplifier through incremental encoder feedback, allowing fine speed regulation and slip monitoring. A built-in tacho generator produces 3 V/1000 rpm, giving the drive an analog velocity signal that remains proportional to shaft speed across the operating range.

The motor is supplied without a blocking brake, so external holding devices or continuous drive torque must be used when the load must stay stationary at power-off. Power conductors exit through a connector on side A, which simplifies cable routing in cabinets where the shaft faces forward. Electrical characteristics correspond to winding code PD, with resistance and inductance values matched to specific amplifier current ratings. The mechanical package is categorized as a motor for analog drives, which means its feedback, commutation, and insulation system are intended for legacy voltage-controlled servo amplifiers rather than fully digital drive systems.
