Why is a holding brake of 6.5 Nm important in the MDD090C‑N‑020‑N2L‑110PR1 motor?

The brake secures the shaft when power is removed, preventing drift and ensuring safety on inclines or with gravity loads. In MDD090C‑N‑020‑N2L‑110PR1 its 6.5 Nm torque is sufficient to hold moderate loads without external braking systems.

What role does the centering diameter of 110 mm play for the MDD090C‑N‑020‑N2L‑110PR1 motor?

This dimension helps align the motor precisely on flanges or mounting plates, reducing misalignment-induced stresses. For MDD090C‑N‑020‑N2L‑110PR1, a 110 mm centering diameter helps ensure coupling repeatability and reduces bearing load.

Why include a shaft seal and keyway in the shaft design of MDD090C‑N‑020‑N2L‑110PR1 motor?

The shaft seal protects bearings and internal components from dust, moisture or particles, extending service life. The keyway ensures positive torque transmission from the shaft to load without slippage during high load or startup for MDD090C‑N‑020‑N2L‑110PR1.

What maintenance factors should be considered due to the keyway shaft when using MDD090C‑N‑020‑N2L‑110PR1?

The keyways can introduce stress risers; periodic inspection of shaft seating and coupling for wear or misalignment is necessary. The key fits correctly and torque transmission interfaces are tight in MDD090C‑N‑020‑N2L‑110PR1 to avoid fretting or fatigue at the shaft‑key interface.

How does the DSF (Digital Servo Feedback) improve motion control?

The DSF system provides high-resolution position and speed feedback, allowing tight loop control with minimal latency. This enhances accuracy during cyclic motions and reduces overshoot or settling times.
