Product Description:

The MAC090C-0-KD-4-C/110-A-0/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Engineered as a motor for analog drives, it converts controlled current from the drive into precise rotary motion for automated machine axes, material-handling stations, and other position-critical tasks in industrial automation. Its mechanical form factor aligns with MAC family dimensions and maintains standardized shaft and mounting interfaces across multi-axis installations. It is commonly used where accurate speed and position control are required across repeated duty cycles.

At the mechanical interface, the motor has a centering diameter of 110 mm, which helps seat it concentrically inside gearbox flanges and reduces radial misalignment. Under continuous rating, it delivers a shaft speed of 1500 min⁻¹, matching drive algorithms tuned for low-speed, high-torque processes. The electromagnetic system uses winding code KD, which corresponds to the resistance, inductance, and thermal constants expected by the drive. Heat produced during operation is removed through natural convection, so no external blower or liquid circuit is required when the enclosure is sized correctly. Power wiring uses a side A connector, allowing cable routing to remain on one face of the cabinet and easing access to the connection point.

Tachometry is handled by a 3 V/1000 min⁻¹ generator, which supplies proportional voltage for analog speed loops and provides a second feedback source alongside the digital channel. Position data comes from an incremental encoder mounted in the standard housing, making the motor compatible with conventional counting cards in legacy control systems. The tacho assembly is the standard version, so maintenance can follow the common MAC service interval without special calibration routines. The motor is supplied without a blocking brake, so any holding torque must come from the drive or from an external clamping device when power is removed. This combination supports legacy automation platforms that still rely on analog regulation and separate feedback processing.
