Product Description:
The MHD071B-061-PP2-UN/SA003 is a servo motor manufactured by Bosch Rexroth Indramat in the MHD Synchronous Motors series. Designed for closed-loop industrial automation axes, the unit converts drive current into controlled rotary motion for positioning tasks that require high precision and repeatable torque. It mounts to machinery as a self-contained electromechanical actuator and pairs with Rexroth digital drives for coordinated multi-axis motion.
At standstill, the motor delivers a continuous torque of 8.0 Nm, while acceleration events can draw a peak current of 50.5 A to reach its characteristic speed of 4,500 rpm. Four pole pairs and a torque constant of 0.77 Nm/A provide a linear torque response. An optically measured absolute position system tracks more than 4,096 revolutions and supplies digital servo feedback to the drive. The integrated holding brake provides 6.5 Nm of holding torque to secure vertical loads. The windings carry code 061 and have an inductance of 7.2 mH, a resistance of 1.45 Ω, and a back electromotive force of 70.0 V/1,000 rpm. Natural convection through the IP65 housing removes heat, while Class F insulation tolerates winding temperatures up to 155 °C. The power and feedback connectors can be rotated through 270° to support cable routing, and the minimum accepted conductor cross section is 1.0 mm². The keyed shaft is sealed against dust and water, and the rotor inertia is 8.7 × 10⁻⁴ kg·m².
The motor has a centering diameter of 95 mm and a square flange measuring 115 mm. These dimensions correspond to the 071 frame class and B length code, while the complete motor has a mass of 8.8 kg. System accuracy of ±0.5 angular minutes supports positional repeatability, and the motor can produce up to 32.0 Nm of short-term torque when commanded. The permitted operating temperature ranges from 0 °C to 40 °C. When the motor is not operating, it may be stored at temperatures from -20 °C to 80 °C. Installation is permitted at elevations up to 1,000 m above mean sea level without thermal derating.
