Product Description:

The MHD115C-024-NG1-AA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts drive power into precisely regulated rotary motion for positioning axes in conveyors, machine tools, and automated handling stations. Used with a compatible drive controller, it supports accurate speed and position regulation during indexing, feed movement, and repetitive transfer tasks. The C-length housing and 115 frame size give the motor a mid-length, high-torque form factor that fits machinery requiring considerable stall force without an oversized footprint.

The motor supplies a continuous standstill torque of 70.0 Nm, and the built-in holding brake secures the shaft with the same torque during shutdowns. The housing is sealed to IP65, so dust and low-pressure water jets do not compromise operation, while heat is dissipated by natural convection without external fans. Feedback is delivered through digital servo feedback (HSF) for closed-loop control, and the position loop can resolve movements to within ±0.5 angular minutes. Class F insulation withstands elevated winding temperatures, the plain shaft connects directly to couplings, a shaft seal helps prevent oil ingress, and the feedback system reports relative rather than absolute position values.

The motor has a 192 mm square flange and a 180 mm centering diameter for accurate pilot engagement. These mounting dimensions help align the motor with machine plates or gearboxes and support stable coupling geometry during operation. Power reaches the stator through an output connector on side A, which can simplify cable routing in many machine layouts, and installation is permitted up to 1000 m above mean sea level. Winding code 024 matches the electrical characteristics expected by compatible Indramat inverters, the motor is suitable for ambient temperatures of 0 to 40 °C, and long-term storage from -20 to +80 °C is permissible.
