Product Description:

The MHD115C-024-PG0-LA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for closed-loop axis control in industrial automation, this permanent-magnet unit couples directly to machinery and supplies moderate to high torque without mechanical gearing. By combining a compact 115 frame size and a C-length stator, the motor occupies less installation space than comparable models while still delivering the continuous stall torque demanded by packaging lines, transfer systems, and metalworking centers. Its synchronous design gives the connected drive fast response to command changes, which helps maintain stable velocity and position control during indexing, feeding, and transfer tasks.

At standstill the motor can provide 70.0 Nm of continuous torque, enabling high load holding without overheating. A flange diameter of 192 mm and a centering recess of 180 mm simplify rigid mounting to standard machine plates while maintaining concentricity. The housing carries an IP65 rating, so dust ingress and low-pressure water jets do not interfere with operation on the factory floor. Cooling relies on natural convection, eliminating blower noise and reducing maintenance in debris-laden areas. Windings are impregnated to Class F thermal limits, allowing copper temperatures up to 155 °C before insulation degradation. The plain shaft transmits torque without key stress concentrations, and the left-side power connector, winding code 024, and the absence of a holding brake support installation in drive chains with external mechanical locking.

For accurate positioning, the motor employs digital servo feedback delivered by an integrated optical encoder. This arrangement achieves a system resolution of ± 0.5 angular minutes, and because its reference scale is Absolute (>4096 revolutions), no datum move is needed after shutdowns. The optical feedback path gives the controller fine rotor-angle information for smooth commutation and stable low-speed motion. Normal operation is specified from 0 to 40 °C, while storage from −20 to 80 °C keeps components within safe thermal limits. The optical measurement method preserves accuracy up to 1000 m above mean sea level, and a shaft seal is fitted to protect the plain shaft against coolant spray.
