Product Description:
The MKD112C-024-GP3-AN is an AC servo motor developed by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Designed for closed-loop positioning and velocity tasks in industrial automation, the motor turns drive output from compatible converters into regulated rotary motion that can be coupled directly to gearboxes, ball screws, or belt transmissions on production machinery. Its electromechanical construction combines permanent-magnet excitation with resolver feedback so motion controllers can calculate rotor angle in real time and adjust current accordingly.
The motor has a continuous stall torque of 38.0 Nm, allowing it to hold or move loads at zero speed without overheating when it stays within the rated current window. Installation interfaces follow an industrial pattern: the centering diameter is 130 mm and the square mounting flange measures 192 mm, giving alignment with gear adapters. Electrical and thermal characteristics are tied to the stator winding code; 024 matches the resistance and inductance values used by compatible Bosch Rexroth drives for medium-voltage operation. Within the MKD line, this unit carries a frame designation of 112, indicating the lamination stack diameter, while the length variant C increases active core height and power density, which affects speed range, acceleration, and inverter sizing.
For mechanical coupling, the motor uses a shaft with keyway so torque can be transmitted through standard keyed hubs, and a shaft seal helps block coolant or lubricant ingress. Power and feedback conductors exit on side A through an output connector that simplifies removal during routine service. A built-in holding brake rated at 70 Nm engages automatically when supply power is removed, providing static load support during vertical-axis downtime. Closed-loop control relies on resolver feedback, which delivers analog sine-cosine signals for relative position detection; when homed, the controller maintains rotor angle with fine resolution without relying on incremental encoders.
