Product Description:

The MAC090B-0-PD-4-C/110-A-0/WI525LX/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it translates command voltages into controlled torque and speed for indexing tables, packaging axes, and other motion tasks in industrial automation. The motor supplies continuous, feedback-regulated rotation that fits mid-frame mechanical envelopes while following the electrical conventions used in legacy Indramat drive racks. Its overall format also suits systems that still rely on analog motion control and need stable rotary response during changing load conditions.

Mechanical attachment starts with a 110 mm centering diameter that fixes the stator concentrically to the machine frame. Thermal management relies on natural convection, so free air circulation around the housing is necessary during prolonged duty cycles. A shaft speed of 1500 rpm is the nominal operating point and aligns with common gearbox ratios for material-handling axes. The electromagnetic circuit uses the PD winding, which gives the resistance and inductance values expected by analog amplifiers. Because the motor has no blocking brake, stationary holding force must be generated by the drive or by an external clamp when power is removed. Tacho quality is standard, which suits normal velocity-loop operation in general automation service.

Cabling and feedback features complement the analog control approach. Mains conductors are brought in through a connector on side A, permitting tight panel layouts when the motor is installed with its right side toward the cabinet wall. The integrated tacho generator produces 3 V/1000 rpm, supplying a proportional speed signal for the drive’s velocity loop. Rotor position is reported by a standard-mounted incremental encoder, which allows the controller to monitor shaft movement during commanded acceleration and deceleration. The motor can alternatively be equipped with tacho feedback, an incremental encoder, or an absolute encoder to match differing controller capabilities. External sensing hardware is not required for basic closed-loop motion.
