Product Description:

The MAC090A-0-ZD-2-C/110-B-0/S01 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Engineered for closed-loop positioning and speed regulation, the unit interfaces with analog drive controllers that command current and velocity through voltage references. In automated machinery, the motor converts electrical input into rotational motion with precise feedback so axis modules, gantries, or processing spindles can maintain controlled movement under changing load conditions. This operating role makes it suitable for applications that require repeatable motion rather than simple fixed-speed rotation.

This configuration is supplied without a blocking brake, so mechanical holding must be handled by external devices when power is removed. The front-end mating flange has a centering diameter of 110 mm, providing a reference for concentric mounting on gearboxes or machine plates. Heat generated by the windings leaves the housing through natural convection, eliminating fans from the motor assembly. Rotor position and speed are returned to the drive by a tacho feedback device that generates a proportional voltage, allowing analog regulation loops to react quickly. Under nominal excitation, the shaft reaches 1500 rpm, a speed suited to moderate-inertia loads in packaging or material-handling systems.

The stator winding identified by code ZD indicates the electrical resistance and inductance profile used with compatible drive amplifiers so current remains within rated limits. Power enters through a plug-style connector on side B, keeping cable bends clear of the machine interface on side A and helping maintain unobstructed mounting access. The tachogenerator produces 3 V/1000 rpm, so at rated speed the controller receives roughly 4.5 V for velocity feedback. As a motor for analog drives, the model uses standard tacho feedback for stable analog loop response. This arrangement supports smooth speed regulation in systems that rely on voltage-based control rather than digital encoder communication.
