The R911287280 (MHD115A-058-PP0-BN) is a servo motor engineered for servo and main drive applications in industrial environments. It features liquid cooling, insulation class F, a keyed shaft with seal, and a flange size of 192 mm with a centering diameter of 180 mm. The motor delivers a continuous torque at standstill of 32.0 Nm and supports nominal and maximum speeds of 4000 RPM and 6000 RPM, respectively. It operates with a rated input current of 5.7 A, yielding 1.8 kW at 60K and up to 4.6 kW at 100K with 10 A input. Position detection utilizes an absolute digital servo feedback encoder system (>4096 revolutions). Power is connected to side B via an output connector. The motor size is 115, motor length is A, and it is supplied without a holding brake.

Frequently Asked Questions

Why is a keyed shaft design chosen for this servo motor?

The keyed shaft ensures firm coupling between motor and load. The setup prevents rotational slip during torque transmission under heavy load.

What role does the holding brake option play in industrial applications?

The holding brake secures the shaft when power is removed. The mechanism prevents load drop or drift in vertical or static holding systems.

How does a centering diameter of 180 mm affect installation quality?

The larger diameter increases surface contact for better alignment. The structure enhances stability and reduces vibration in rigid mounts.

Why is power connection to side B beneficial during setup?

The side B orientation allows neater cabling in compact assemblies. The routing improves accessibility and reduces risk of connector stress.

How does digital servo feedback with integrated encoder improve control accuracy?

The digital feedback provides real-time position signals with minimal delay. The integration ensures faster control response and higher positioning precision.
