The R911316911 (MHD115B-024-NP1-LA) is a synchronous servo motor designed for industrial applications, providing a peak theoretical torque of 160 Nm and a continuous standstill torque of 50 Nm. It has a maximum speed of 4000 rpm and operates with a peak current of 145 A. The motor incorporates a keyed shaft with shaft seal, houses a digital servo feedback (HSF) encoder for relative position detection, and includes a holding brake rated at 70 Nm. The housing, built to IP 65 standards, supports natural convection cooling. It measures 115 mm in size, motor length B, with a centering diameter of 180 mm and a flange size of 192 mm. The unit functions in ambient temperatures from 0 to 40 °C, at altitudes up to 1000 meters, and features a left-oriented power connector.

How does the holding brake contribute to the operational safety of this servo motor?

The holding brake provides 70 Nm torque to secure the motor when power is off. The feature prevents unwanted shaft movement and maintains position during downtime.

What installation advantage does the left side power connector provide?

The left side connector simplifies cable routing in dense control cabinets. The layout improves accessibility and reduces installation time during setup.

How does natural convection cooling benefit this servo motor in continuous operation?

The convection cooling design removes heat without external devices. The system supports long-term stability and consistent torque output during extended use.

Why is a keyed shaft with a shaft seal preferred for precision machinery?

The keyed shaft ensures torque transfer without slippage under load. The shaft seal protects internal parts from dust and fluid ingress in industrial environments.

How does the motor maintain torque accuracy during standstill conditions?

The motor provides 50 Nm continuous torque even when stationary. The stable torque performance ensures controlled motion in positioning or clamping processes.
