The R911285063 (MHD112C-058-NG0-LN) is a Bosch Rexroth synchronous servo motor featuring an electronically commutated design and a low rotor moment of inertia, optimized for dynamic industrial applications requiring frequent start-stop operation. The motor is constructed with a 130 mm centering diameter and a 192 mm flange, and it utilizes a plain shaft with a shaft seal. It is equipped with liquid cooling and includes a digital servo feedback (HSF) encoder for relative position detection. The motor delivers a continuous standstill torque of 38.0 Nm, has a 'C' length, a left-oriented power connector, complies with winding code 058, and is supplied without a holding brake.

What advantages does liquid cooling bring to MHD112C-058-NG0-LN in thermally demanding duty cycles?

Its liquid cooling removes stator heat directly for maintaining winding temperatures and magnetic flux density during sustained torque delivery, thus preserving 38 Nm at standstill. It also lowers enclosure heat load for easing machine thermal management and enabling denser layouts.

How does the HSF digital servo feedback in the MHD112C-058-NG0-LN affect loop stability and resolution at high speeds?

The HSF interface provides high-rate incremental data with motor memory for enabling precise commutation and stiff velocity/position loops under dynamic profiles. It improves phase alignment and reduces quantization effects versus low-resolution devices for supporting accurate contouring in CNC and robotics.

How do the 192 mm flange and 130 mm centering diameter influence mounting precision and shaft alignment?

The DIN-style B5 flange and centering register constrain runout and concentricity for minimizing coupling misalignment and bearing side-loads. Its mechanical datum pairing shortens alignment time and improves repeatability during motor swaps on pick-and-place or machine-tool axes.

What is the functional impact of the plain shaft with shaft seal on MHD112C-058-NG0-LN in washdown or dusty environments?

It simplifies coupling selection while the radial seal limits ingress of coolant or particulates toward the front bearing. It also protects lubricant films and extends bearing life where mist, chips or cleaning fluids are present.

What cabling and panel-layout benefits arise from the left-oriented power connector on MHD112C-058-NG0-LN?

The left-exit power connector streamlines routing in cabinets or gantry carriages sharing cable chains for separating encoder and power paths to limit EMI. It simplifies strain relief and keeps bend radii within specification.
