Product Description

The MHD115A-058-NG0-BN is a synchronous servo motor. It belongs to the MHD product line from Bosch Rexroth. In combination with compatible Bosch Rexroth controllers, the MHD115A-058-NG0-BN motor is widely deployed for industrial applications that include machine tools, paper machines, automation and packaging machines. As per the type code, the motor frame size is 115 and the frame length is A. The motor frame size defines essential motor dimensions, which in the case of the MHD115A-058-NG0-BN are 180 millimeters centering diameter and 192 millimeters flange size. The motor frame length defines the continuous torque at standstill. Continuous torque at standstill for the MHD115A-058-NG0-BN motor is 32 Nm with natural convection at 60K overtemperature, 36.5 Nm with natural convection at 100K overtemperature and 60.8 Nm with liquid cooling. In combination with frame size and frame length, the winding code specifies the motor output data.

Continuous current at standstill for the MHD115A-058-NG0-BN motor is 36.6 Amps with natural convection at 60K overtemperature, 42.1 Amps with natural convection at 100K overtemperature and 69.5 Nm with liquid cooling. The rated motor output is 1.8 kilowatts with natural convection at 60K overtemperature, 4.6 kilowatts with natural convection at 100K overtemperature and 17.5 kilowatts with liquid cooling. Features of the MHD115A-058-NG0-BN motor include digital servo feedback, plain shaft with sealing ring, and power connector on side B. The motor time constant is 60 minutes with natural convection at 60/100K overtemperature and 20 minutes with liquid cooling. The recommended minimum electrical power cable cross-section is 6 mm² with natural convection at 60K overtemperature and 10 mm² with liquid cooling. Maximum speed of the motor is 6000 RPM. The motor insulation class, according to DIN VDE 0530, is F.
