The MPN R911291655 (MHD112B-035-PG1-BN) is a brushless synchronous servo motor designed for industrial automation. It employs permanent magnet excitation and includes a shaft, stator, rotor, bearings, and a motor encoder. The motor features a 192 mm flange with a 130 mm centering diameter, and a B-length black housing weighing approximately 34 kg. Shaft design is plain with a sealing ring, and it incorporates a 22 Nm rated holding brake. Feedback is provided by digital servo feedback with an integrated multiturn absolute encoder. The power connector is oriented to side B. Cooling options include natural convection or surface cooling. The motor supports a continuous standstill torque of 28.0 Nm and operates within a 0°C to 40°C temperature range.

What role does the integrated holding brake play during power loss?

It locks the motor shaft automatically when power is removed, preventing mechanical drift or load backdrive. This is critical for vertical or load-bearing applications like lifts or presses.

What maintenance considerations apply to the grease-lubricated bearings?

The sealed bearings require no periodic relubrication, minimizing downtime. Routine visual checks for leakage or noise are sufficient to ensure continued smooth operation.

How does the motor’s synchronous design affect dynamic response?

Permanent magnet synchronization delivers immediate torque response to command inputs. It enables precise acceleration control ideal for pick-and-place and servo indexing systems.

Can the integrated brake operate without a separate controller?

Yes, the brake is electrically engaged and released directly through motor power lines. This simplifies system wiring and reduces control cabinet complexity.

How does the absolute encoder with multiturn detection enhance system safety?

It retains position data even after power-off, eliminating the need for homing routines at startup. This feature prevents unintentional movement and shortens machine recovery times.
