Product Description:

The MAC090C-0-KD-4-C/110-B-0/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It provides controlled torque and speed to mechanical axes in automated production equipment, converting drive current into rotary motion with the precision required for coordinated positioning and process timing. By integrating electrical feedback devices directly at the motor, the unit supports closed-loop motion tasks common in packaging, textile, and handling installations.

In mechanical terms, the centering diameter measures 110 mm, so the motor seats directly into flanged housings without additional sleeves. Heat is removed through natural convection, eliminating the need for forced-air or liquid cooling hardware and simplifying cabinet layout. Rated speed is 1500 min⁻¹, establishing the base electrical frequency for sizing analog drive electronics and gear ratios. Mains power reaches the stator windings through a connector on side B, which determines cable routing and bend radius outside the machine frame. Rotor velocity is monitored by a tacho generator that outputs 3 V/1000 min⁻¹, giving the drive a linear voltage reference for closed-loop speed regulation.

Electrical characteristics originate from winding code KD, which sets the resistance, inductance, and current limits applied during amplifier tuning. Position information is supplied by an incremental encoder mounted in the standard location. When required, the motor also supports tacho feedback, incremental encoder, or absolute encoder options for compatible legacy regulators. Because a blocking brake is not present, any static holding torque must be delivered by the drive or an external clamp. The tacho circuit uses standard quality components to maintain repeatability within analog loops, and the unit remains a motor for analog drives, ensuring compatibility with earlier Rexroth VT-MD series controllers.
