The R911282843 (MHD112C-058-NG3-BN) is an AC servo motor engineered for industrial applications requiring high torque output in constrained spaces. This model features a 112 mm frame size, a centering diameter of 130 mm, and a 192 mm flange, with a motor length designated as type C. It employs liquid cooling for thermal regulation and Class F insulation for sustained operation at elevated temperatures. The unit supports a continuous standstill torque of 38.0 Nm, incorporates a 70.0 Nm holding brake, and utilizes a plain shaft with a shaft seal. Position feedback is provided through a digital servo encoder (HSF), with relative position detection. The power connection is configured to side B with an output connector. Winding code is 058.

What does HSF digital servo feedback with relative position detection change during commissioning of MHD112C-058-NG3-BN versus incremental/resolver systems?

The HSF serial feedback carries motor data and high-resolution position for easing tuning and cable noise immunity. It can skip full re-homing after orderly stops in many architectures.

How is the 70 Nm holding brake on MHD112C-058-NG3-BN applied for vertical axes and emergency stops?

The 70 Nm, spring-applied, electrically released brake holds position when torque ceases for preventing back-drive on vertical axes. It is important to verify MHD112C-058-NG3-BN against reflected inertia and worst-case gravitational plus friction loads before commissioning.

What mounting features of MHD112C-058-NG3-BN ease mechanical integration into existing frames?

The flange 192 mm with 130 mm pilot fits common mounting classes for drop-in swaps. Its length C and a sealed plain shaft on MHD112C-058-NG3-BN simplify coupling alignment and maintain ingress resistance.

How does the plain shaft with shaft seal affect coupling choice and contamination resistance on MHD112C-058-NG3-BN?

It supports clamp or elastomer couplings for low backlash without keyway stress concentrations. Its integrated seal on MHD112C-058-NG3-BN helps exclude spray, fibers and fines in harsh duty.

How do side-B power orientation and a rotatable feedback socket streamline harness layout on MHD112C-058-NG3-BN?

Its side-B power orientation lets harnesses exit away from guideways or operators.Its feedback flange socket can be rotated after plugging, so MHD112C-058-NG3-BN sets cable angle to relieve cabinet strain.
