Product Description:

Bosch Rexroth Indramat manufactures the MHD115C-035-NG0-AA in the MHD Synchronous Motors series. This servo motor is designed for precise positioning and velocity control in automated production lines, packaging stations, and material-handling axes. By pairing with compatible digital drive controllers, the unit converts electrical input into controlled mechanical rotation and supplies regulated torque to servo-controlled shafts within industrial machinery. Its synchronous design supports closed-loop motion tasks where repeatable speed changes and accurate stopping are required. It is suitable for axes that must start, stop, and reverse under drive control without losing position consistency.

The motor delivers a continuous standstill torque of 70.0 Nm, allowing heavy loads to be held without additional gearing. A centering diameter of 180 mm aligns the frame on mounting surfaces, while the 192 mm flange pattern provides rigid fixation through its square bolt circle. The housing is rated IP65, and heat is removed through natural convection, eliminating the need for forced air or liquid cooling. Motion feedback comes from Digital servo feedback (HSF), which uses an optical measurement method and operates in relative mode. The motor has a plain shaft, motor length code C, and size 115 stator lamination. Power is routed to side A through an output connector, and the motor comes without a holding brake to reduce inertia during high-speed cycles. This arrangement helps keep cable routing orderly where machine space is limited around the mounting area.

The motor maintains positional deviation to within ± 0.5 angular minutes, which supports accurate indexing and repeatable axis movement. Windings marked with code 035 use Class F insulation and permit winding temperatures up to 155 °C during continuous duty. Operation is permitted in ambient temperatures from 0 to 40 °C, while storage is permitted from -20 to +80 °C to protect magnets and bearings when the machine is idle. Installation altitude can reach 1000 m above mean sea level without derating, and a factory-installed shaft seal helps prevent lubricant migration along the plain shaft. The shaft seal also helps keep contaminants away from the bearing area during normal machine operation.
