Product Description:

The MHP115C-058-HP0-BNNNNN is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat for the MHP Synchronous Motors series. In automation equipment, it converts drive current into precise rotary motion for synchronized acceleration, dwell periods, and repeatable positioning on packaging lines, gantry axes, and similar applications where high torque and accurate feedback are required. The unit uses natural convection cooling and is supplied without a holding brake, so external mechanical measures must secure the load when power is removed, especially when the axis must remain fixed at standstill. This cooling method also avoids the need for a separate motor-mounted fan assembly.

The motor produces 70.0 Nm of continuous torque at standstill, allowing it to support substantial static loads while maintaining fine control during low-speed operation and indexing. Windings built to insulation class F tolerate elevated internal temperatures during cyclic duty, which helps protect the winding system during repeated starts and stops. A die-cast aluminum enclosure and terminal box conform to IP65, helping keep out dust and low-pressure water jets commonly found on factory floors. Rated performance is maintained within an ambient range of 0 to +40 °C, so the motor can operate under normal plant conditions without auxiliary cooling. Rotor position is reported by an incremental encoder with 2048 increments, giving the drive controller enough resolution for stable velocity control, accurate commutation, and repeatable indexing.

Mechanical power is delivered through a keyed shaft with a sealing ring, which provides positive torque transmission and helps limit lubricant migration from connected gearboxes. This arrangement supports direct coupling to pulleys, couplings, and other transmission elements used in servo-driven machinery. Power conductors exit through a connector on side B, which supports cable routing opposite the load side in compact machine layouts and helps keep the connection area accessible. The motor has a 115 mm stator diameter, giving it the inertia characteristics expected for mid-range robot joints and other medium-size axes. Electromagnetic behavior is set by winding code 058, which matches the impedance values used by compatible Indramat drive converters and helps maintain stable current control across commanded speed changes and load variations.
