Product Description:

The Bosch Rexroth Indramat MHD115C-035 is part of the MHD Synchronous Motors series and functions as a servo motor for numerically controlled axes in conveyors, presses, and machining centers. When paired with a digital drive controller, it provides feedback-based rotation so the host PLC can command accurate speed or position loops. Its closed-loop operation helps correct speed deviations during changing load conditions and repeated start-stop cycles. This electromechanical design supports continuous duty and high precision, making it a common choice where tight motion tolerances and repeatable cycle times are required in industrial automation.

The motor can supply a continuous standstill torque of 70.0 Nm, allowing static load holding without thermal overload. This is useful on axes that pause under load between indexing moves or controlled positioning steps. A centering diameter of 180 mm eases concentric alignment against a pilot recess, and the square flange dimension is 192 mm for rigid mounting. Frame size code 115 identifies the stator outside width and helps with coupling or gearbox selection. The flange and centering features also help keep the shaft axis aligned with mating machine components. Length designation C extends the active lamination stack, increasing copper cross-section and surface area so the motor can dissipate heat under prolonged load.

The motor uses winding code 035, which sets phase resistance and back-EMF constants for compatibility with Indramat drive algorithms. In this configuration, the stator winding balances torque and maximum speed, supporting rapid acceleration without excessive current draw. The winding selection also affects how the motor behaves across low-speed torque production and higher-speed operation. The dimensions outlined earlier create the overall mounting envelope, which helps with flange fit and available machine space. Added steel and copper in the length-C frame contribute extra thermal mass, enabling short overload peaks while remaining inside insulation class limits and maintaining winding life expectancy.
