Product Description:

The MAC090B-0-PD-1-B/110-B-0-I01250 is an AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended to operate with analog drive amplifiers, delivering closed-loop torque and speed regulation in automated machinery such as packaging stations, pick-and-place axes, and material-handling modules. This unit converts electrical energy from its drive into mechanical rotation that can be commanded precisely in industrial motion sequences.

The motor mounts to a machine frame through a centering pilot of 110 mm, ensuring axial alignment with coupled loads. Under rated excitation, it turns at a nominal speed of 1500 rpm, a value suited to moderate-inertia applications that still require accurate velocity control. Heat produced by copper losses leaves the housing through natural convection, so no external blower is needed. Electromagnetic behavior is set by winding code PD, which matches the impedance and current limits of designated drives in the MAC family. For velocity feedback to the controller, a built-in tacho generator outputs 3 V/1000 rpm, and this linear voltage allows the drive to calculate actual speed and close the analog control loop.

The mechanical holding function is external because the motor is supplied with no blocking brake, so static load retention must be handled by the drive or by a machine-side clamp. Rotor position data for commutation is provided by incremental encoder feedback, giving the drive both coarse and fine resolution without introducing absolute multi-turn components. Power conductors enter through a connector on side B, a layout that lets cable routing face away from guide rails or moving parts. The design is classified as a motor for analog drives, confirming compatibility with drive cards that sample tacho voltage instead of using fully digital interfaces.
