Product Description:

The MHD071B-061-PG0-UP is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It serves as a drive element for positioning tasks in automated machinery, where closed-loop control and high repeatability are required. The motor integrates digital servo feedback to report speed and position directly to the drive controller, allowing precise motion without additional sensors. It is intended for compact, high-response servo applications.

The unit can produce a continuous stall torque of 8.0 Nm, allowing it to maintain torque at standstill within thermal limits. Its housing is sealed to IP65, which helps protect internal components from dust and water jets during washdown or coolant exposure. A square mounting flange of 115 mm interfaces with standard mechanical adapters, and a centering recess of 95 mm helps align the shaft concentrically with couplings. Rated operation is permitted from 0 to 40 °C, and the F-class winding insulation supports high internal thermal endurance during normal operation. Heat is removed by natural convection. The plain shaft works with low-backlash couplings, and the motor has no holding brake, so static load retention must be supplied externally.

The optical feedback system limits composite positioning error to ± 0.5 angular minutes. This helps the controller maintain accurate angular correction during fine positioning. Power and encoder plugs can be swiveled through 270°, which helps with cable routing in tight electrical enclosures. Long-term storage is allowed from -20 to +80 °C, and the motor can start reliably at elevations up to 1000 m above mean sea level. Absolute position capture across more than 4096 revolutions eliminates homing moves after power loss, and the built-in shaft seal helps prevent lubricant migration into the bearing cavity.
