Rated output of 710 kW at 2980 rpm gives the H17RL 400X3-2 high power density for drives where every centimetre of installation space matters. This 2-pole electric motor from VYBO Electric is designed as a three-phase electric motor for operations requiring stable starting, precise torque transfer and reserve capacity for long-term loading.
The robust cast-iron construction helps maintain assembly rigidity during vibration, frequent starts and continuous operation. In practice, this is appreciated by operators of rolling lines, process-water pumping stations, compressor stations, mixing equipment, conveyor lines, crushers and large fans where mechanical durability and long service life without unnecessary downtime are important.
2-pole electric motor for drives with high power density
The combination of rated torque of 2275 Nm and starting characteristics makes it possible to accelerate the load even where the drive is connected to a massive technological system. This allows the asynchronous electric motor with a squirrel-cage rotor to be used in sectors where reliable energy transfer to gearboxes, pumps or compressor units is required.
- Operation of heavily loaded steel conveyors.
- Drive of large axial fans in the energy sector and metallurgy.
- Pumping process water in industrial treatment plants.
- Crushing and screening aggregate in mining lines.
- Mixing viscous media in chemical production.
- Compressing air in high-output compressor assemblies.
- Rolling and winding material in metallurgical operations.
Cast-iron body for stability under continuous load
Industrial use also requires rigid bearing support, control of thermal stress and resistance to long-term mechanical wear. That is why this asynchronous electric motor with a squirrel-cage rotor is based on a design that handles continuous operation well and maintains stable parameters even under demanding shift regimes. Insulation class F together with temperature rise B supports safe thermal operation under load.
Energy efficiency in large technological systems
Efficiency of 96,1 % and a power factor of 0,89 help maintain the drive’s energy efficiency at a level that is noticeable in the total operating costs of large factories. OEM manufacturers of technological systems also appreciate the option to choose the frequency, because 60 Hz is also available, simplifying export projects and standardisation across different markets.
Rated current of 1202 A at △ 400V and 697 A at Y 690V provides sufficient input for precise sizing of the power supply when designing switchboards and protective components. Weight of 3680 kg, external starting inertia of 232,000 kg·m² and GD² moment of inertia of 21,200 kg·m² are values that can be used when designing the line, foundations and connection to downstream technology. 6220C3 bearings on both the DE and NDE sides support smooth operation over long duty cycles.
VYBO Electric supplies a solution for customers who need not only the motor itself but also coordination with a specific technological process and the actual installation conditions of the operation.
