Product Description:

The MAC090A-0-ZD-4-C/110-B-0 is a three-phase AC servo motor built by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for analog drives, it delivers precise closed-loop motion in industrial automation equipment where stable torque and position control are required. In assembly lines, pick-and-place gantries, and general machinery, the unit converts drive commands into controlled shaft rotation while keeping the motor package compact for installations with limited space.

Mechanical integration is simplified by a centering seat of 110 mm, which allows repeatable alignment to machine frames or gearbox interfaces. Under rated conditions, the rotor turns at 1500 rpm, a speed that suits many low-speed positioning axes without requiring intermediate gearing. Heat is removed by natural convection, so the housing should remain exposed to ambient airflow instead of enclosed recirculated air. The motor has no blocking brake, so holding torque during power loss must be supplied by external clamping or drive torque. Power conductors exit through a connector on side B, which helps routing in crowded enclosures and keeps cable entry predictable.

The winding code ZD identifies the motor’s electrical resistance and inductance values for use with compatible analog drive amplifiers. Speed monitoring uses incremental or absolute encoder tachofeedback, allowing the control system to process relative movement as well as retained position data without external transducers. For velocity verification, the tacho generator outputs 3 V/1000 rpm, and its signal quality is classified as standard. This feedback arrangement gives the drive continuous speed information during acceleration, deceleration, and steady-state operation, which supports consistent motion on production equipment that depends on repeatable servo response.
