The R911279545 (MHD090B-058-NG0-UN) is a synchronous servo motor designed for integration into servo systems, featuring a brushless construction for high reliability and reduced operational noise. It complies with DIN 42948 for its flange interface and provides an IP65-rated housing for protection against dust and low-pressure water jets. The motor operates with a relative digital servo feedback encoder (HSF), has a plain shaft with a shaft seal, and supports a continuous torque at standstill of 12.0 Nm with a rated speed of 4000 RPM. The unit is liquid-cooled and suitable for natural convection or surface cooling, accommodates a 110 mm centering diameter and 140 mm flange, and offers power and feedback via turnable connectors over 270°. Maximum leakage current may reach 3.5 A, necessitating proper grounding.

Frequently Asked Questions

Does the MHD090B-058-NG0-UN require external cooling equipment?

Yes, it uses liquid cooling, so an external cooling circuit must be integrated. Proper coolant flow is essential to maintain motor temperature and performance stability.

How does relative position detection affect commissioning?

Because it uses relative position feedback, homing is required at startup. This ensures the control system establishes an accurate reference point.

How is continuous torque delivery influenced by standstill conditions?

The motor can sustain rated torque without rotation, but sufficient cooling must be active. This prevents overheating during prolonged holding operations.

Can the power connector orientation on the MHD090B-058-NG0-UN ease installation?

Yes, the connector rotates within 270°, allowing flexible cable routing. This reduces strain on wiring in tight cabinet or machine layouts.

How does an HSF digital encoder improve system response?

It provides high-resolution feedback for precise control loops. This enables smoother motion profiles and accurate synchronization in multi-axis setups.
