Product Description:
The MHD071B-061-PG1-UN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It provides closed-loop rotary actuation for machine tools, pick-and-place modules, and packaging stations where precise speed and position control is required. The unit interfaces with Indramat digital drive controllers for coordinated multi-axis motion across automated cells. Its synchronous motor design supports responsive acceleration and stable axis behavior during repeated starts, stops, and directional changes.
The centering recess is 95 mm, allowing secure alignment to a gearbox or bracket, while the square flange spans 115 mm to match common motor adapter patterns. Under continuous excitation, the rotor can deliver 8.0 Nm of standstill torque. Electrical wiring enters through power and feedback connectors that can be rotated through 270°, which helps when cable routing space is limited or when the motor is mounted in a tight machine frame. Digital servo feedback with an integrated encoder sends incremental and absolute position data directly to the drive so current, speed, and position loops remain closely controlled during motion.
A permanent-magnet holding brake supplies 5.0 Nm of static torque to secure vertical or indexing axes when power is off. Position detection remains reliable over more than 4096 revolutions, so the control system can retain multi-turn position information after interruptions. The rotor stack uses winding code 061, paired with size 071 and length B laminations for quick acceleration with controlled inertia. A plain shaft with a shaft seal helps resist fluid ingress while permitting direct coupling to belt pulleys or flexible couplings. The sealed housing helps keep contaminants away from the internal windings and supports use in demanding industrial environments.
