Copper rotor for long service life places this drive in a category where every cycle, every kilowatt-hour and every shutdown matters. The H17R 500-A-8-6 model with an output of 800 kW is designed as a 700 rpm electric motor for applications requiring compact power, stable traction and low losses under long-term load. In practice, this means lower thermal stress on the winding, better energy efficiency and predictable operation in technological systems running continuously.
700 rpm electric motor for reliable operation of large lines
This three-phase electric motor is intended for operators who need precisely controlled power transmission to compressors, pumps, mills or conveyors. The copper alloy of the rotor helps maintain low losses even during long operating windows, so the motor better handles thermal loads and maintains efficiency within the range that is decisive for industrial drives. Combined with IE4 Super Premium efficiency, the energy demand of the entire line is reduced without the need to alter the basic process architecture.
- The copper rotor provides a longer service life under continuous load.
- IE4 Super Premium efficiency supports lower operating costs.
- Advanced temperature monitoring increases control over the condition of both the winding and bearings.
- IEC size 500 mm facilitates design into robust industrial assemblies.
- An 8-pole electric motor provides suitable characteristics for applications with higher torque at lower speeds.
Technical reserve for continuous operation
Rated current of 97 A, power factor of 0,83 and rated torque of 10255 Nm provide a stable basis for processes where load fluctuations are unacceptable. Insulation class F together with temperature rise B supports resistance to long-term thermal stress. For OEM manufacturers of large technological systems, it is also important that a weight of 6800 kg and rotor moment of inertia of 44,0 kg·m² allow more precise sizing of starting, couplings and variable-frequency control within the assembly.
Applications in heavy industry
The motor is suitable for cement mills, mining conveyors, water pumping stations, desulfurization units, compressor stations, rolling lines, mixers for bulk materials, drum dryers, ore crushers, cooling-tower fans, extruders, agitators in the chemical industry, belt conveyors in port terminals and drives for technological presses. In these operations, its stability during long running periods and temperature monitoring through PT100 elements in the winding and bearing locations are particularly beneficial.
VYBO Electric for industrial projects with long operating cycles
VYBO Electric supplies solutions intended for operations with high availability and a clear service plan. For large factories, it is crucial that a high-voltage electric motor of this type combines performance with precise monitoring of machine condition and a design prepared for integration into both new and modernized lines. If you need a drive for equipment that must run stably and without unnecessary compromises in efficiency, take advantage of the offer and design a solution with reserve capacity for further years of operation.
