Product Description:

The MHP115B-058-HG1-ANNNNN is a synchronous servo motor built by Bosch Rexroth Indramat as part of the MHP Synchronous Motors series. Within an automation cell, this motor converts drive-controller current into tightly regulated rotary motion for indexing tables, pick-and-place axes, or tooling spindles. Its construction focuses on delivering high continuous torque while occupying a compact frame, making it a common choice for multi-axis packaging, printing, and material-handling equipment. The motor is intended for closed-loop motion tasks where stable speed control and accurate positioning are required throughout repeated operating cycles. That combination suits machines that must start, stop, and settle quickly without sacrificing torque at low speed.

Under natural convection, the motor sustains a continuous standstill torque of 50.0 Nm, eliminating the need for external blowers or liquid cooling. The cast housing is rated to IP65, so airborne dust and directed water cannot enter the enclosure during washdown cycles. A plain shaft with a sealing ring allows direct coupling to gearboxes while helping keep lubricants and contaminants separated. For power-off holding, a permanent-magnet brake applies 70.0 Nm of torque, preventing back-driving on vertical or lifting axes. Position feedback is provided by an incremental encoder with 2048 increments per revolution, giving the control loop fine angular resolution for smooth speed regulation and repeatable homing. Because cooling is passive, the unit can be used where added airflow hardware would complicate machine layout or enclosure cleaning.

The electromagnetic system follows winding code 058, matching the electrical characteristics expected by compatible Rexroth drives. Class F insulation permits winding temperatures well above ambient, supporting sustained output across the permitted site range of 0 to +40 °C. The frame diameter denoted by size 115 provides the magnetic cross-section needed for the rated torque while keeping rotor inertia moderate for rapid acceleration. Power cabling exits toward side A through a molded connector, which helps maintain a compact installation envelope and orderly cable routing. Length designation B indicates the overall motor length for this housing size.
