Product Description:

The MAC090B-0-PD-4-C/110-A-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is supplied as a compact rotary actuator for positioning and velocity control in industrial automation when coupled to analog drive amplifiers. The motor converts commanded current into shaft torque, enabling closed-loop motion axes in packaging machinery, material handling stations, and similar equipment. Its compact format suits axes where installation space is limited and repeatable motion is required over frequent start-stop cycles.

For mechanical integration, the housing has a centering hub diameter of 110 mm that aligns the flange to gearboxes or mounting plates, and a flange-mounted blocking brake holds the load when power is removed. Thermal management relies on natural convection; no external blower or liquid circuit is needed, so ambient airflow must be available around the housing. Electrically, the stator uses the PD winding code, and the rotor is rated for a nominal speed of 1500 min⁻¹, providing constant velocity in systems driven by 50 or 60 Hz mains-referenced controllers. These values set the continuous torque curve and the voltage matching used with standard Indramat analog amplifiers.

All connections are concentrated on the drive end, and the power connector is oriented toward side A, which helps keep cable routing direct inside a cabinet. Rotor speed is reported by a tacho feedback device, allowing the controller to adjust current with fast response during changes in load or speed. This tachogenerator produces a feedback signal of 3 V/1000 min⁻¹, which the amplifier uses to maintain stable regulation across the working range. The unit is identified as a motor for analog drives, underscoring its compatibility with Indramat TDM and similar analog servo controllers where velocity loops are closed directly in the drive rather than in a digital motion CPU. The tacho quality is specified as standard for general-purpose automation requirements.
