Product Description:

The MHD115C-058-PP1-BA servo motor is built by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a rotary actuator for industrial automation, it works with digital drive controllers to supply torque for production axes, material-handling equipment, and machining centers. The motor combines feedback electronics and mounting features in one frame, which helps support precise position control during repeated duty cycles. It is suitable for applications that require steady acceleration, accurate stopping, and dependable motion on continuously cycling equipment.

The motor delivers a continuous standstill torque of 70.0 Nm, allowing static loads to be held without overheating. Its enclosure carries an IP65 rating, so dust and water jets do not penetrate during washdowns. A mounting flange measuring 192 mm aligns the motor on the machine face, while rotor position is monitored through digital servo feedback based on an optical measurement method. The integrated encoder supports absolute referencing for more than 4096 revolutions, which lets the drive retain position information over multiple turns. Heat is removed through natural convection, so no external blower is required. Size 115, length C, and winding code 058 identify the motor's electromagnetic characteristics, while the permissible operating ambient temperature ranges from 0 to 40 °C. A 70 Nm holding brake is fitted for power-off retention.

A keyed shaft transfers torque to couplings, and a shaft seal helps keep lubricant in place while limiting contaminant entry. System feedback provides a positioning accuracy of ± 0.5 angular minutes, which supports controlled motion in interpolated and point-to-point axis movements. For storage or shipment, the motor can tolerate temperatures from -20 to +80 °C. The windings use Class F insulation to support thermal endurance at elevated internal temperatures. Power conductors exit on side B through an output connector, and installation is permitted at altitudes up to 1000 m above mean sea level without derating. This cable orientation can simplify routing in machines where the motor is mounted close to guarding, gearboxes, or adjacent axis hardware.
