Product Description:

The MAC090B-0-PD-4-C/110-B-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, the motor supplies controlled torque and speed to automated machinery where closed-loop regulation is required. It integrates electrical feedback and precise mechanical alignment so multi-axis assemblies can keep motion profiles consistent.

Mounting accuracy starts with a centering diameter of 110 mm, allowing the housing to fit directly against standard flange surfaces. Heat leaves the stator by natural convection, eliminating the need for forced airflow or liquid cooling. Under rated conditions, the rotor reaches a nominal speed of 1500 rpm, giving the system a predictable baseline for gear ratio selection. Power leads exit through a connector on side B, simplifying cable routing when the motor is installed in confined cabinets. A built-in tacho generator delivers 3 V/1000 rpm of proportional voltage, which the analog drive uses to close the speed loop with minimal latency. The tacho operates with standard accuracy for routine supervision.

The motor uses the PD winding code, which determines coil resistance and current demand for this version. Because there is no blocking brake, mechanical holding torque must be provided externally whenever the axis is de-energized. For velocity feedback, the unit offers tacho feedback and incremental or absolute encoder signals, while position data are supplied by an integrated incremental encoder mounted on the rear shaft extension. This combination supports fine resolution at low speeds and allows the same motor to interface with proportional or digital controllers that accept square-wave channels. It is suitable for pick-and-place units, feeders, and other motion modules without changing the motor’s mechanical footprint.
