Product Description

The Bosch Rexroth MHD093C-058-NG0-LN is a MHD series digital servo motor. The motor housing is designed for natural convection or liquid cooling. The motor performance varies with the cooling method used. The rated data for natural convection and 60K overtemperature are: 11.4 Nm torque, 4.9 Amps current, 2.7 kilowatts power, 320 Volts voltage and 133 Hertz frequency. The rated data for natural convection and 100K overtemperature are: 17.4 Nm torque, 7.8 Amps current, 4.4 kilowatts power, 327 Volts voltage and 133 Hertz frequency. The rated data for liquid cooling and 60/100K overtemperature are: 38.2 Nm torque, 16.6 Amps current, 9.5 kilowatts power, 355 Volts voltage and 133 Hertz frequency. The rated motor speed is 2000 RPM for all operating conditions. The maximum speed for the MHD093C-058-NG0-LN motor is 4500 RPM.
