An energy-efficient drive for continuous use provides high output reserve and stability even in long-term operations. The H27R 5001-6-6 model with an output of 1120 kW belongs to a category where not only power density but also efficiency, reliable cooling and resistance to loading in high-power lines are monitored. In practice, it is a 1000 rpm electric motor intended for heavy industry and power technologies where every loss has a direct impact on operating costs.
IC611 air-to-air cooling keeps the inside of the motor clean
The H27R-HD-Modular series uses a closed IC611 cooling circuit that helps separate internal air from the surrounding environment and increases suitability for dusty or corrosive operations. This approach supports long-term temperature stability even under high load, which is important for drives with high inertia and processes where continuous operation is expected. Combined with IE4 efficiency, energy losses are reduced while economical operation in demanding high-power applications is supported.
The stator winding is impregnated using VPI technology, which increases resistance to moisture, dust and vibration. The motor design uses insulation class F and temperature rise class B, creating a favorable reserve for operating cycles with higher thermal stress. Torque characteristics are also important for HV drives because starting torque reaches 1,1 times the rated torque, breakdown torque 2,4 times the rated torque and starting current 6,7 times the rated current. When designing the power supply and protection, this facilitates correct sizing of the starting system.
Parameters supporting reliable operation at 6000 V
This high-voltage electric motor operates at 6000 V, has a rated current of 130,3 A, rated speed of 994 rpm, rated torque of 10761 Nm and a power factor of 0,87. Rotor inertia of 64,0 kg·m² and load inertia of 1420,0 kg·m² provide important input when assessing starting, braking and system dynamics. The DE bearing arrangement NU238-C3+6040-C3 and NDE NU230-C3 is designed for long-term industrial use where precision and durability under high load are decisive.
