Product Description:
The MHD093C-058-PP0-BP is a servo motor produced by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. It serves as a rotary actuator in CNC stations, pick-and-place gantries, and other industrial axes that require high positional repeatability and tight speed regulation. Integrated sensors report rotor status to the drive, allowing immediate correction when the commanded trajectory changes. By combining a compact 093 frame with a C-length stator, the unit delivers medium power density while fitting standardized IEC-based mounting footprints.
Its mechanical interface uses a centering diameter of 130 mm and a 140 / 150 mm mounting flange, giving rigid alignment to adjoining gear or load couplings. At standstill, the motor supplies 23.0 Nm of continuous torque, and class F insulation supports this loading without excessive temperature rise. Sealing reaches IP65, while convection cooling is supported by cable exits protected to IP68, so no auxiliary fans are required. A digital servo feedback encoder is integrated for closed-loop control with an overall accuracy of ±0.5 angular minutes. Power is fed through an output connector on side B, and torque is transmitted by a keyed shaft with a shaft seal. The motor has no holding brake, and winding code 058 identifies the stator electrical layout.
The motor has stated operating and storage limits for reliable service. It maintains rated characteristics between 0 to 40 °C, and it can be stored without power at -20 to +80 °C without affecting the insulation or bearing grease. Operation is permitted up to 1000 m above mean sea level, so derating is usually unnecessary in factory buildings. Rotor position is sampled optically, and the absolute scale preserves count information for more than 4096 turns through absolute (>4096 revolutions) detection. This allows controllers to resume motion after power cycles while keeping calibration intact.
