The MPN R911285287 (MHD115B-024-NP0-AA) is a brushless, digital servo motor from the MHD115 series, designed for industrial automation environments. This variant features grease-lubricated bearings, a keyed main shaft with a shaft seal, and supports electronic commutation via permanent magnets. The motor incorporates digital servo feedback (HSF) with relative position detection. It provides continuous torque of 50 Nm (natural convection, 60K) and up to 57 Nm (100K), while supporting 75 Nm with surface cooling. Rated output ranges from 4.4 kW to 14.4 kW at 2000 RPM depending on cooling. The R911285287 measures 192 mm (flange) with a 180 mm centering diameter, 'B' motor length, and features a power output connector oriented to side A. It is supplied without a holding brake. This unit should be handled by trained personnel.

Frequently Asked Questions

What is the benefit of using a digital servo feedback encoder in this motor?

The encoder ensures precise position control and enables accurate synchronization with other motion axes. The feedback loop improves overall system responsiveness and stability during dynamic operations.

Why is a keyed shaft with seal used in servo applications?

The keyed shaft ensures firm torque transmission between motor and load. The seal protects the motor bearings from dust and moisture during operation.

How does the 192 mm flange contribute to system integration?

The flange follows standard mounting dimensions for easy alignment. The design supports consistent coupling with gearboxes and industrial frames.

What advantage does a side-A output connector offer during installation?

The connector orientation simplifies cable management in compact spaces. The layout minimizes wiring strain and enhances electrical reliability.

How does continuous torque at standstill benefit precision control systems?

The torque stability maintains fixed load positions without drift. The feature enables steady force delivery for holding and positioning applications.
