Product Description:
The MHD115C-024-PG1-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It combines a 115 frame size with a C-length housing to provide high torque density for industrial positioning axes that demand rapid acceleration and repeatable speed control. The motor integrates digital servo feedback, and its plain shaft has a seal that helps block oil or coolant ingress, making the unit suitable for enclosed machining cells and material-handling systems. This configuration is commonly used on feed axes, rotary tables, and transfer systems where fast response and stable positioning are required across repeated cycles.
The motor can sustain 70.0 Nm of continuous standstill torque, while an internal holding brake of the same rating secures the load during power-off conditions. Heat is removed through liquid cooling, allowing the stator to remain within thermal limits during prolonged high-load duty cycles. A protection rating of IP65 guards the winding and bearings against dust and low-pressure water jets, and the mounting flange circle measures 192 mm for connection to standard machine or gearbox interfaces. The centering diameter is 180 mm for precise alignment, and power conductors exit through a connector on side B. Optical measurement is used by the encoder to capture rotor position, and the brake helps prevent unintended movement when the axis is not energized.
Total system precision is specified at ±0.5 angular minutes, and the feedback system provides Absolute (>4096 revolutions) position detection for multi-turn tracking. The windings use insulation class F, and the motor remains operational from 0 to 40 °C while storage is permitted from -20 to +80 °C. Installation is permitted up to 1000 m above mean sea level without derating. Winding code 024 identifies the electrical characteristics used for this motor configuration, and the multi-turn feedback supports position retention across several shaft revolutions.
