Product Description:
The MHD115C-035-NG1-AN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop positioning and speed control, it delivers regulated rotary motion to automated axes, tool spindles, and material-handling stations in industrial automation lines. Its synchronous design supports stable torque production and predictable dynamic response during repeated start-and-stop cycles. In automated equipment, this type of motor is commonly paired with a compatible drive so commanded motion can be corrected continuously as load conditions change. This makes the motor suitable for applications where accurate motion, smooth speed regulation, and dependable feedback are required throughout normal machine operation.
This motor supplies 70.0 Nm of continuous standstill torque, while heat is removed through a liquid-cooling jacket integrated into the housing. A sealed construction with an IP65 protection rating keeps internal components isolated from dust and directed water jets. Rotor position is detected by a digital servo feedback (HSF) encoder, and the drive can correct motion errors to a system accuracy of ±0.5 angular minutes. The motor includes a holding brake for load retention during power-off states, which helps keep the axis from drifting when external holding force is needed. Position data are acquired optically, and the feedback is relative rather than absolute. The winding designation is 035, and the motor has a plain output shaft with a shaft seal to limit fluid ingress.
Installation details include an operating range of 0 to 40 °C and storage capability from −20 to +80 °C. The square flange measures 192 mm, and the centering pilot is 180 mm to align the C-length frame on machinery. The insulation system is rated Class F, which corresponds to a 155 °C winding limit, and the motor may be installed up to 1000 m above mean sea level without derating. Power and feedback cabling exit on side A through an output connector, which keeps both connections grouped on the same end of the housing. Size code 115 and motor length C identify the housing format used for this motor, while the plain shaft supports direct coupling to gearboxes or pulleys.
