Product Description:
The MHD115C-058-NP0-BN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Serving as the primary electromechanical actuator on automated stations, it converts drive output into tightly regulated torque and speed so that pick-and-place arms, presses, or conveyors follow programmed motion profiles. Its integrated resolver-based electronics send real-time rotor data to the controller, allowing the axis to track reference commands even when external loads fluctuate.
At standstill, the motor can continuously deliver 70.0 Nm, enabling it to hold heavy fixtures without overheating. Accurate mechanical centering is supported by a 180 mm locating diameter on the front face, while the mounting flange spans 192 mm so it aligns with standardized machine frames. Heat produced by copper losses is removed through liquid cooling, which helps keep winding temperature low during high-duty cycles. Rotor position is captured by digital servo feedback (HSF), which sends high-resolution data to the drive for velocity and phase control. The motor has frame length C in the 115 frame, and the power leads exit through an output connector for straightforward cable routing.
Mechanical power is transmitted through a keyed shaft, and an integral shaft seal helps block oil or coolant from migrating along the journal into the stator housing. The power connector is located on side B, keeping cabling clear of adjacent modules in tight installations. The stator uses winding code 058, which corresponds to the electrical characteristics expected by the matching drive. Because the encoder reports position in a relative format, an external homing routine is required after power-up. The motor is supplied without a holding brake, so load securing must be handled by the drive or by external clamps.
