Electric motor 800 kW, 1488 rpm, 400 V / 690 V, H17RL 400X4-4 LV

In production lines, a problem often arises when a drive is unable to sustain the load over the long term without unnecessary downtime, overheating and frequent maintenance intervention. The H17RL 400X4-4 model is designed to deliver greater reliability in production operation under such conditions, especially where the range of 1400-1500 rpm and stability under variable load are monitored.

Compact solution with high power for the 1400-1500 rpm range

This class of drive combines a compact solution with high power and high power density, which is advantageous when modernising switchgear and machine assemblies. The 400 V / 690 V electric motor can be integrated into the existing low-voltage infrastructure without unnecessarily extensive modifications and, in practice, helps replace older units in operations where space and delivered energy both matter.

The H17RL Compact PRO in this version operates at 800 kW, with a rated current of △ 400V 1363 A and a rated current of Y 690V 790 A. The rated speed of 1488 rpm supports use in applications requiring an operational reserve, while the rated torque of 5134 Nm provides the necessary force during start-up and process stabilisation. For operations that monitor the 1400-1500 rpm range, this is a practical solution with an emphasis on controlled performance.

Adaptation to the environment for industrial electric motors 400/690 V

The possibility of environmental adaptation is important in production plants where dust levels, humidity or the washing regime of the technology change. The available IP56, IP65, IP66 and IP67 protection ratings make it possible to design the motor for a specific operation without compromise in integration. Industrial electric motors 400/690 V can thus be better adapted to conveyors, pumps and technological units with higher demands on protection.

The H17RL 400X4-4 model has a starting torque ratio Tst/Tn of 120%, a breakdown torque ratio Tmax/Tn of 220% and a starting current ratio Ist/In of 700%. Efficiency of 96.3% and a power factor of 0.88 help keep operating costs under control, while insulation class F and temperature rise B support long-term operation in industrial deployment. From the drive design point of view, this is a solution that works well as a three-phase 400/690 V motor.

Construction and standard equipment for long service life

The standard equipment includes a steel fan cover for better protection of the cooling section, reinforced bearings protected by a steel cover, high-temperature-resistant grease, a metal terminal box with a stronger design and reinforced bearing shields for higher mechanical durability. The rotor cage is designed as a solid aluminium cage, and both the DE and NDE bearings are of type 6326C3, which contributes to stable operation during long production cycles.

The H17RL Compact PRO belongs to the Heavy Duty process performance class and is developed and manufactured specifically for European industry, especially for Western Europe. For this reason, it is naturally suitable for operations dealing with drive modernisation, replacement of older machines or unified standards across a group of production plants. In this category, it also proves itself as a 4-pole electric motor in applications where high operational discipline is required.

In technical practice, this drive is used in mineral crushers, plastic extruders, chemical mixing units, industrial network compressors, flue gas extraction fans, process water pumps, bulk material conveyors, rolling mills, cable winders, paper cutters, centrifuges, cement mills, asphalt mixing plants and belt sorters. A weight of 4000 kg, an external starting inertia of 524 kg·m² and a moment of inertia GD² of 52.0 kg·m² are important for the design of mechanical mounting, especially in equipment with frequent starts and long engagement periods.

If you need to assess a replacement for an existing drive or a new integration into technology, VYBO Electric can supply a solution from a professional range with support from its own research and development.
