Product Description

The Bosch Rexroth MHD093C-058-NG0-RN is a synchronous servo motor. The housing of the motor is designed for liquid cooling or natural convection. Mechanical parameters of the motor include 0.00030 kg m² rotor moment of inertia, 4500 RPM maximum speed, 23.5 kilograms weight and 88 Nm theoretical maximum torque. The time constant varies with cooling method used: it is 75 minutes for natural convection and 25 minutes for liquid cooling. The recommended cross-section of the motor power wires also varies with cooling method: it is 4 mm² for liquid cooling, 2.5 mm² for natural convection at 100K overtemperature and 1.5 mm² for natural convection at 60K overtemperature. Rated speed of the MHD093C-058-NG0-RN is 2500 RPM and the characteristic speed is 3000 RPM. With natural convection and 60K overtemperature, the continuous stall torque at standstill is 23 Nm and the continuous stall current is 18.5 Amps.

With natural convection and 100K overtemperature, the continuous stall torque at standstill is 28 Nm and the continuous stall current is 24.5 Amps. With liquid cooling and 60/100K overtemperature, the continuous stall torque at standstill is 43.7 Nm and the continuous stall current is 35.2 Amps. The MHD093C-058-NG0-RN supports digital servo feedback. The motor power connector is on the right side. An integrated holding brake is not available on the MHD093C-058-NG0-RN. The motor shaft is plain and includes a seal. Housing of the MHD093C-058-NG0-RN is IP65 rated. The installation of the motor should be carried out by trained and qualified personnel. Only those spare parts and accessories that are approved by Bosch should be used with the motor. Safety instructions included in the product documentation should be implemented to prevent equipment damage and injury to personnel.
