H17RL-450X3-4 brings high power density to operations where space, stability and long-term loading are decisive. This 1400 rpm electric motor is designed for large process and energy drives that require reliable operation under continuous load and precisely matched output within a robust industrial solution.
In this design, VYBO Electric relies on robust cast-iron construction that helps damp vibrations and maintain mounting accuracy even in demanding mechanical environments. This is why a three-phase electric motor of this type performs well where shock starts, long duty cycles and high requirements for the service life of bearings and mechanical components are common.
1400 rpm electric motor for heavy industry and continuous operation
Rated speed of 1490 rpm provides a stable basis for applications where smooth energy transfer without unnecessary fluctuations is expected. Combined with an output of 1000 kW and rated torque of 6409 Nm, this is a solution that performs well when starting large inertial systems and during long-term operation of technological lines.
In practice, this low-voltage electric motor can be used, for example, on rock crushers, pumping stations for process media, mining conveyors, compressor units, mills in cement plants, mixing equipment in the chemical industry, high-volume-flow fans, extruders in plastics production, transmissions in metallurgical lines and large winders in the paper industry.
Robust cast-iron construction for long service intervals
The cast-iron motor body increases resistance to mechanical stress and improves behaviour under long-term thermal loading. This is particularly important in plants where the drive is installed in limited space while having to withstand uninterrupted operation without frequent maintenance interventions.
A weight of 5500 kg and a shaft height of 450 mm support stable installation in technological systems where high dynamic loads are expected. This helps the three-phase electric motor behave predictably even in assemblies where starting torque and inertia are decisive factors in drive design.
Compact output for spaces with limited installation room
Compact output is particularly advantageous where high power must remain concentrated within a reasonable construction length and without excessive installation-space requirements. This solution simplifies integration into existing production systems, modernisations and replacements for older drives with a similar voltage regime.
- Rated current of 1703 A at △ 400 V supports use in high-power distribution systems with an emphasis on direct supply.
- Rated current of 990 A at Y 690 V corresponds to operation in large industrial networks.
- A starting torque ratio of 110 % helps start loaded systems.
- A breakdown torque ratio of 220 % increases reserve capacity during short-term operating peaks.
- A starting current ratio of 750 % is important when designing protection and starting.
Efficiency selection according to the plant’s energy strategy
The option to choose the efficiency class allows the drive to be adapted to the requirements of the specific technology, budget and planned operating life. For modernised production lines, this is especially practical where total energy consumption and the need to reduce operating losses are monitored without changing the process logic.
Availability of IE3, IE4 and IE5 gives technologists scope to set the efficiency level according to plant targets. Efficiency of 96,3 % and a power factor of 0,88 also support economical operation in applications where the motor runs in long duty cycles and changes in consumption affect overall production costs.
Operating parameters that help with drive design
Insulation class F and temperature rise B are important under long-term load, especially where the surroundings are thermally demanding or the machine is part of technology with limited cooling. The rotor cage made of copper bars supports durability during repeated starts and improves motor behaviour during heavy starting.
DE bearing 6328C3 and NDE bearing 6328C3 provide the basis for stable running in assemblies where precise mounting and long service intervals are expected. External starting inertia of 654,000 kg·m² together with a GD² moment of inertia of 64,000 kg·m² is useful when designing a system that must handle dynamic changes without unwanted overload.
Thousands of satisfied VYBO Electric customers use similar solutions in metallurgy, mining, energy and processing industries, where component reliability is tested every day under real operating conditions.
