Product Description

The Bosch Rexroth MHD112C-035-NG3-LN is a digital servo motor. It is part of the MHD product line. Salient features of MHD motors include high reliability, maintenance-free operation, overload protection, easy cabling and simple startup. The motors are permanent-magnet motors with electronic commutation. The main components of the motors are a shaft, stator, bearings, encoder, flange socket, holding brake, shaft seal and rotor with permanent magnets. The main shaft on the MHD112C-035-NG3-LN is plain and has a sealing ring. Shafts with key are also available for MHD motors. The MHD112C-035-NG3-LN includes a 70 Nm holding brake. The brake prevents shaft rotation until a 24 Volts DC release signal is applied. The power cable from the drive controller connects to a connector on the left side of the motor housing.

The MHD112C-035-NG3-LN motor supports digital servo feedback. The feedback is sent to the drive controller through a separate feedback cable. The motor housing is suited to natural convection or surface cooling. Surface cooling is suitable for high loads. Natural convection is suitable for lower loads. The MHD112C-035-NG3-LN is a flange-mounted motor. The size of the flange is 192 millimeters. With natural convection at 60K overtemperature, the rated motor speed is 2500 RPM, the rated torque is 15.8 Nm, the rated current is 9.1 Amps, the rated power output is .7 kilowatts, the rated voltage is 303 Volts and the rated frequency is 167 Hertz. The moment of inertia of the motor rotor is 0.0273 kg m². The MHD112C-035-NG3-LN can deliver maximum 148 Nm theoretical torque. The housing of the motor is sealed and is IP65 rated. The surface of the motor housing is painted matte black (RAL 9005).
