Product Description:

The MHD115C-024-PG1-RA is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for high-torque axes in CNC systems, conveying equipment, and forming machinery where accurate rotary motion is required. The motor converts controlled three-phase power into precise shaft rotation, allowing the drive system to manage speed, position, and load holding with closed-loop control. This supports repeatable starts, stops, and dwell periods on axes that operate under changing loads.

Mechanical integration uses a flange of 192 mm and a centering diameter of 180 mm, allowing direct seating on standard machine frames without extra adapters. The motor has a plain shaft with a shaft seal, and power enters through a right-side connector to keep cable routing compact. At standstill, it delivers 70.0 Nm of continuous torque, and the integrated holding brake provides the same torque to secure the load when power is removed. The housing carries an IP65 rating to protect internal parts from dust and water jets. Cooling is provided by natural convection, and the windings use F-class insulation to handle elevated temperatures during cyclic duty.

Position control relies on digital servo feedback with an optically scanned scale, giving a system precision of ± 0.5 angular minutes. The absolute multi-turn encoder stores position over more than 4096 revolutions, so the controller can recover rotor angle after a power cycle without losing multi-turn information. The feedback system also helps the drive maintain stable velocity and accurate positioning during continuous motion. Safe operation is permitted at ambient temperatures from 0 to 40 °C and at installation heights up to 1000 m above mean sea level. Storage is allowed between −20 °C and 80 °C without damage to the motor. Winding code 024 identifies the electrical characteristics required by the matching drive amplifier, while the size 115 frame and length C give the motor a balance of inertia and torque.
