Product Description:

The MHD115C-058-PP0-BA is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It supplies rotational drive in automated machinery where closed-loop speed and torque control are required, such as packaging axes, gantry drives, or material-handling stations. The motor integrates with Rexroth digital drives to convert electrical energy into mechanical motion while providing precise position feedback for coordinated multi-axis movement. This makes it suitable for applications that require repeatable positioning, controlled acceleration, and stable speed regulation during frequent start-stop cycles.

At standstill, it can deliver a continuous torque of 70.0 Nm, allowing heavy loads to be held without overheating. A square mounting flange of 192 mm aligns with standard interfaces, and the 180 mm centering diameter keeps the stator concentric with the driven assembly. Winding code 058 sets the electrical values expected by the drive, while the C length variant balances power density with installation depth. Power is transmitted through a keyed shaft that helps prevent slip between the shaft and the coupled element, and this arrangement supports direct coupling to gearboxes, pulleys, or other driven components.

Cooling is done by natural convection, so installation must allow free air circulation around the housing because there is no external blower. Electrical supply is routed through an output connector on side B, which can simplify cable runs in tight enclosures. Rotor position is monitored by digital servo feedback, and the encoder provides absolute feedback over more than 4096 revolutions, giving the drive controller immediate knowledge of angle after power-up. The motor is supplied without a holding brake, so static loads must be secured by the drive or external mechanics. A shaft seal is installed to limit contamination of the front bearing when the motor operates in oily or dusty environments.
