Product Description:
The MHD093C-058-NG1-AN servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It provides rotational power and precise speed control for automated equipment such as pick-and-place arms, gantry drives, and printing rollers. When paired with a compatible drive controller, it serves as the electromechanical actuator that follows position or torque commands in closed-loop motion systems. This arrangement supports repeatable machine motion during frequent starts, stops, and speed changes without requiring a separate external feedback device.
At standstill, the motor can deliver a continuous torque of 23.0 Nm, allowing static load holding without overheating. Heat is removed through a jacket that supports liquid cooling, which helps keep winding temperature low during prolonged duty cycles. The housing carries a protection rating of IP65, so dust is kept out and water jets will not affect internal components. Position feedback is supplied by digital servo feedback (HSF), giving high-resolution speed information to the drive for stable closed-loop control. A rectangular flange measuring 140 / 150 mm simplifies attachment to gearboxes or machine frames. Additional mechanical features include a 130 mm centering diameter, a plain shaft, and a power connector on side A. Winding code 058 and motor length C identify the motor's electrical setup and active iron stack.
For safety and process stability, the integrated holding brake supplies 22.0 Nm of static torque to help prevent axis drift during power-off conditions or emergency stops. The optical measurement system achieves an accuracy of ± 0.5 angular minutes, supporting fine incremental moves in indexing tables and robotic joints. Rated operation is permitted in ambient air from 0 to 40 °C. Storage is allowed from -20 °C to 80 °C, and installation is permitted up to 1000 m above mean sea level. Thermal endurance is supported by Class F insulation, and a shaft seal is fitted to help limit contamination at the output. Relative position detection supports drive-based multi-turn counting, which helps the control system maintain position information across repeated movements.
