Product Description:

The MAC090B-0-PD-1-B/110-A-0/I01250 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It serves analog drive systems by converting current setpoints from a servo amplifier into controlled torque and rotary motion for machine tools, packaging axes, and assembly stations. The permanent-magnet rotor and sensor package support closed-loop regulation so velocity and position remain stable under variable loading. This arrangement also helps the motor respond smoothly to speed changes during repeated start, stop, and positioning cycles.

A centering diameter of 110 mm aligns the housing with precise concentricity to adjoining mechanics. Heat produced during operation is removed through natural convection, eliminating the need for external fans in tight control cabinets. The shaft can maintain a nominal speed of 1500 rpm, which matches common gearbox ratios in material-handling equipment. For analog velocity loops, a built-in tacho generator provides 3 V/1000 rpm, delivering a linear speed-proportional signal to the drive electronics. The PD winding code indicates the electrical characteristics used by the matching drive.

The motor is supplied with no blocking brake, so external clamping or continuous drive torque must secure loads when power is off. Rotor position is monitored by incremental encoder feedback, which supplies quadrature pulses for high-resolution motion control. Power conductors exit through a connector on side A, which can simplify cable routing when the machine layout favors a single wiring direction. Classified as a motor for analog drives, it integrates directly with legacy controllers that modulate current and velocity through continuous voltage references. This makes it useful in retrofit applications where existing control architecture is retained.
