Product Description:

The MAC090C-0-KD-4-C/110-A-1/WI521LX is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Serving as a rotary actuator for closed-loop industrial automation, it converts command signals into controlled torque and speed for positioning tables, packaging axes, and material-handling equipment. Its design suits drive systems that rely on analog control channels rather than fully digital interfaces.

The winding code KD indicates electrical values matched to compatible Indramat analog drives. Rated speed reaches 1500 rpm, allowing predictable velocity control in moderate-speed processes. Heat is removed through natural convection, so installation should allow free airflow around the housing without requiring external cooling hardware. A standard blocking brake keeps the shaft locked during power-off conditions, which helps support vertical loads until drive power returns. Mounting accuracy is aided by the 110 mm centering diameter, which aligns the flange with gearboxes or machine plates. The motor also uses a standard tachometer arrangement for speed loops that do not require high-resolution velocity data.

The power conductors terminate in a side A power connector, which can simplify cable routing when the motor is mounted inside tight enclosures. Velocity monitoring relies on a tachometer that delivers 3 V/1000 rpm, a level suited to analog speed regulators that interpret proportional voltage. Position control is furnished by an incremental encoder with standard mounting, and the housing supports the manufacturer’s arrangement for tachometer feedback together with incremental or absolute encoder hardware. Classified as a motor for analog drives, the model fits legacy installations that still use ±10 V command structures. The separate feedback channels support both speed regulation and position monitoring without changing the motor’s basic cooling or mounting arrangement.
