Product Description:

The MHP115A-058-HG0-RNNNNN synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MHP Synchronous Motors series. This size 115 unit is used on mid-range rotary axes where reliable continuous torque must be delivered directly from the drive without forced ventilation. When paired with a compatible servo amplifier, the motor converts commanded current into precise rotary motion for pick-and-place modules, packaging machinery, and other automated equipment. Its application range suits machines that require accurate positioning together with steady torque during repeated cycles.

With natural convection cooling, the motor supplies 32.0 Nm of continuous standstill torque, allowing it to hold a sustained load without exceeding normal thermal limits. The output is transferred through a plain shaft with a sealing ring, which supports torque transmission while helping keep contaminants away from internal components. The enclosure has an IP65 rating, so it resists dust ingress and low-pressure water jets in industrial environments. Operation is permitted from 0 to +40 °C, which suits common indoor factory conditions. Insulation class F supports winding temperatures up to 155 °C, and the compact A length helps conserve installation space where axis spacing is limited.

Position feedback is provided by an incremental encoder with 2048 increments, giving the drive fine resolution for velocity control and homing functions. The motor is supplied without a holding brake, so load retention at standstill must be handled by drive torque or an external mechanical device when power is removed. Winding code 058 matches the electrical resistance and inductance values expected by compatible power modules. The power connector is oriented on the right side, which can simplify cable routing when several axes are mounted next to each other on the same machine frame.
