Product Description:

The MAC090A-0-ZD-4-C/110-B-0/DI520LV is a permanent-magnet servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. In automated cells, it pairs with analog drive amplifiers to generate controlled rotary motion for feed axes, handling modules, and light machining spindles. The motor converts electrical power into mechanical torque and returns velocity feedback to the controller so commanded speed and position profiles remain stable under variable load. This operating style makes it suitable for machinery that depends on smooth response during repeated starts, stops, and speed changes.

Its nominal shaft speed is 1500 min⁻¹, which is the continuous operating point around which the drive regulator is tuned. A centering diameter of 110 mm aligns the stator housing to machine frames with consistent radial accuracy. Winding code ZD indicates the phase resistance and inductance used by the associated amplifier. For tachometer monitoring, the motor generates 3 V/1000 min⁻¹, giving the control loop a proportional voltage signal that scales linearly with speed. Heat is released to ambient air by natural convection, eliminating the need for forced-air or liquid cooling hardware and simplifying installation in enclosed machine spaces.

Rotor position data are supplied by an incremental encoder with shock-damped mounting, which improves signal stability in installations subject to vibration. Mains power enters through a connector on side B, an arrangement that keeps cabling on the non-drive end for easier routing inside tight enclosures. The motor has no blocking brake, so external holding devices must be used when power-off torque retention is required. Classified as a motor for analog drives, the unit works with velocity or current-loop electronics that process analog reference signals. Its feedback arrangement supports consistent motion control in general-purpose industrial applications where stable low-speed behavior and repeatable axis response are important.
