Product Description:

The MHP115B-058-HG1-AFNNNN synchronous motor is built by Bosch Rexroth Indramat for the MHP Synchronous Motors series. It serves as a rotary actuator that couples with digital drives to move tooling, transport stages, or robotic joints with closed-loop precision. The motor design targets medium-to-high-power axes where a sealed housing and integrated cooling simplify installation on automated lines.

The operating ratings describe how this motor handles continuous load, intermittent demand, and closed-loop feedback. In natural convection, the rotor can deliver a continuous torque of 50.0 Nm, giving a constant load reference when airflow is minimal. A jacket designed for liquid cooling removes additional heat so that higher intermittent currents can be applied without overshoot. The housing is sealed to IP65, helping keep dust and washdown spray away from internal components. Position data returns through an incremental encoder with 2048 increments, allowing the drive to resolve shaft movement to within 0.18 degrees per pulse. For static holding or emergency stops, the integrated brake supplies 70.0 Nm of countertorque against back-drive. A plain shaft with a sealing ring suppresses lubricant escape, and the 115 frame with length code B sets the mechanical envelope when the motor is flange mounted.

Thermal margins are bounded by an ambient range of 0 to +40 °C, and heat endurance is reinforced by class F insulation that tolerates winding temperatures up to 155 °C during duty peaks. Service wiring enters through a power connector located on side A, noted as connector on side A, which helps route cables clear of nearby fluid lines. This placement can simplify cable routing where coolant hoses and power leads share limited space around the machine frame. Electrical characteristics follow winding code 058, which informs the matched drive of the motor’s expected voltage constants and current ratings for vector control.
