Product Description:

The MHP115C-058-HG0-ANNNNN is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MHP Synchronous Motors series. It serves as the rotary actuator in automated axes where precise velocity and position loops are maintained by a connected drive controller. By converting three-phase electrical input into controlled mechanical rotation, the unit supports tasks such as coordinated milling heads, pick-and-place gantries, and indexing stations in general factory automation. Its frame size suits applications that need substantial torque without moving to a larger motor class.

The motor develops 70.0 Nm of continuous standstill torque and is cooled by natural convection, so external blowers are not required for most duty cycles. Its approved ambient operating range is 0 to +40 °C, so surrounding air must remain within that limit during operation. A plain shaft with a sealing ring transfers torque while helping block contaminants at the bearing area. Rotor position is reported through an incremental encoder with 2048 increments, giving the controller fine resolution for commutation and speed feedback. The cast-aluminum housing is rated IP65, which helps keep dust and water jets away from internal motor parts.

Power enters through a single-cable connector on side A, which simplifies routing in narrow machine frames. The winding code 058 is matched to the electromagnetic geometry of frame size 115 and the medium motor length C, providing torque characteristics suited to mid-range acceleration profiles. Insulation class F allows elevated winding temperatures without harming the insulation system under normal operating limits. Because the unit is supplied without a holding brake, static load holding must be provided by external hardware or drive torque when the axis is stopped.
