Product Description:

The MHD115A-058-PP1-AN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as an electromechanical actuator in automated machinery, converting drive-supplied current into regulated rotary motion for axes that require high positional accuracy and fast cycle changes. Its synchronous design supports repeatable motion control, while the liquid-cooled housing helps maintain stable operating temperature during demanding duty cycles.

The motor delivers a continuous standstill torque of 32.0 Nm, which allows it to hold load at zero speed without overheating. A flange diameter of 192 mm matches standard machine frames and helps maintain accurate centering during installation. The stator jacket is equipped for liquid cooling, so heat is removed by coolant circulation rather than ambient air. When motion stops, a holding brake rated at 70.0 Nm secures vertical or indexing loads until power and control are reapplied. The frame size is 115, placing the unit in the higher torque range of the MHD family while remaining suitable for installations with moderate space limits.

The output spindle uses a keyed shaft, allowing positive mechanical locking with pulleys or couplings. Position data is generated by an integrated digital encoder with absolute feedback for more than 4096 revolutions, which removes the need for homing after power cycles. Power conductors exit on side A through an output connector, which simplifies cable routing and strain relief. Winding code 058 identifies the electrical characteristics expected by compatible Bosch Rexroth Indramat drives. Additional features include motor length code A, a shaft seal that helps block lubricant migration, and a liquid-tight housing that remains compatible with the specified cooling circuit and side-mounted power orientation.
