Product Description:
The MHD093A-058-NP0-RA is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In industrial automation cells, this motor converts controlled electrical power into precisely regulated rotary motion, allowing positioning tables, pick-and-place heads, and packaging axes to follow commanded velocity or position profiles generated by a drive controller. It has motor length A and frame size 093, giving it a compact format for machine axes that need accurate servo response and straightforward integration into standard industrial equipment.
At standstill, the motor delivers 12.0 Nm of continuous torque. A housing rated IP65 blocks dust ingress and low-pressure water jets, permitting installation outside sealed cabinets. Mounting concentricity is guided by a 130 mm centering diameter, while heat is removed solely by natural convection, eliminating fans or liquid channels. Operation is permitted in ambient conditions from 0 to 40 °C, and temperatures beyond this range require torque derating. Insulation class F permits winding temperatures up to 155 °C, a shaft seal retains lubricant when the keyed shaft drives couplings, and the power lead exits to the right through a dedicated power connector. Because the unit is supplied without a holding brake, mechanical locks or drive torque must secure the load whenever power is removed.
Mechanical integration uses a square flange measuring 140 / 150 mm, matching common gearboxes and machine plates. Position feedback is provided by a digital servo feedback (HSF) encoder that uses an optical method to generate incremental and commutation signals, enabling relative positioning accuracy of ± 0.5 angular minutes. The motor uses winding code 058, which matches the electrical characteristics expected by the associated drive. Permitted storage conditions range from −20 to +80 °C, and installation is allowed up to 1000 m above mean sea level.
