Product Description:

The MHP115B-058-HG0-LFNNNN is a synchronous motor built by Bosch Rexroth Indramat in the MHP Synchronous Motors series. Within automated production cells, it functions as the primary rotary axis element, translating controlled three-phase drive currents into precise torque and velocity for positioning tables, pick-and-place heads, and material-handling equipment. The motor is intended for liquid-cooled drive packages that require high continuous output without increasing frame size.

Under natural convection, the motor can deliver a continuous standstill torque of 50.0 Nm, giving machinery enough holding force to resist static loads during dwell periods. Thermal energy is removed through a housing prepared for liquid cooling, so winding temperature rise remains limited during prolonged duty cycles. The housing has an IP65 rating, which helps prevent dust ingress and withstands low-pressure water jets. Class F insulation permits winding temperatures up to 155 °C. Rotor position is reported to the controller by an incremental encoder with 2048 increments, supporting fine speed regulation and homing routines.

The specified ambient operating window of 0 to +40 °C is the range where full ratings can be applied without derating. Mechanical power is transmitted through a plain shaft with a sealing ring, which helps block lubricant escape and protects the bearing set from spray. Motor cables exit through a connector on the left side, which can simplify routing in multi-axis gantries that share a common cable track. The motor uses frame size 115 with length code B and winding code 058, giving a balanced ratio between inertia and torque density. The unit is supplied without a holding brake, so the axis must be held at standstill by drive torque or an external device when required.
