Product Description:

The MAC090A-0-ZD-4HC/110-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It serves as a precision actuator that converts drive currents into controlled rotary motion, allowing closed-loop position and velocity control on automated assembly stations, transfer lines, and metal-cutting machinery. In typical automation use, it works with an external amplifier to maintain repeatable motion when load conditions change during operation.

The motor’s continuous operating point uses a nominal speed of 1500 rpm, which provides a baseline for selecting gear ratios and motion profiles. Thermal dissipation is handled by natural convection, so adequate airflow around the housing is required instead of forced cooling hardware. Accurate shaft alignment is supported by a centering diameter of 110 mm, which matches standard flange interfaces on gearboxes and mounting fixtures. Integrated tacho generation delivers 1.5 V/1000 rpm, providing proportional feedback for analog velocity loops without an external sensor. Winding code ZD indicates the stator configuration and corresponds to a specific drive current range, so the connected amplifier can deliver rated torque without saturation.

A standard blocking brake holds the shaft when power is removed, preventing load drift on vertical axes. Position data can be returned through tacho feedback with an incremental or absolute encoder, allowing either speed regulation or full positioning depending on the installed transducer. Mains conductors enter through a connector on side A, so power cables must be routed toward that face of the housing. The unit is classified as a motor for analog drives, so its control loops are intended for voltage or current command amplifiers rather than fully digital inverters.
