Product Description:

The MHD115C-035-PP1-AA is a brushless AC servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. With a 115-frame stator in the C length, it integrates a keyed shaft, a shaft seal, and digital position feedback so motion controllers can command precise rotary movement. As a synchronous servo motor, it is intended for axes that need repeatable acceleration, controlled deceleration, and stable speed regulation under changing loads. The unit converts electrical energy into accurately regulated torque and speed, making it suitable for tool changers, pick-and-place arms, and other automated stations that demand reliable closed-loop positioning in machining, packaging, and material-handling cells.

At standstill, the motor can deliver 70.0 Nm continuously without exceeding its thermal limits. The aluminum housing is sealed to IP65, so airborne dust and low-pressure water jets do not compromise the enclosure during normal industrial use. A square mounting flange of 192 mm and a 180 mm centering pilot help align the motor to the load, while the power leads exit on side A through an output connector for straightforward cable routing. Heat generated in the stator is removed by natural convection, permitting installation where forced airflow is unavailable. Rated performance is maintained at ambient temperatures from 0 to 40 °C, and the digital servo feedback encoder uses an optical measurement method to monitor rotor position.

The integrated holding brake engages automatically when power is removed to help secure suspended or vertical loads. Position feedback is absolute over more than 4096 revolutions, and each commanded move can be verified within ±0.5 angular minutes of system accuracy. Class F winding insulation provides thermal headroom for intermittent peak duty, helping the motor tolerate normal heating during repeated motion cycles. The motor can be installed at elevations up to 1000 m above mean sea level without derating. Storage from -20 to +80 °C helps protect magnets and bearings while the unit is out of service, and the multi-turn feedback supports applications that rotate through more than one complete revolution.
