Electric motor 630 kW, 2980 rpm, 400 V / 690 V, H17RL 400X2-2 LV

The range of 2900-3000 rpm gives this drive a practical basis for lines that need high output without unnecessary oversizing of the space or the power supply infrastructure. The H17RL 400X2-2 model is designed as a low-voltage asynchronous electric motor for demanding technologies, where 630 kW only matters when it can be used for the long term in stable operation. In practice, this means reliability for pumps, compressors, crushers and conveyors that operate in continuous mode.

Compact solution with high power density for the 2900-3000 rpm range

The compact nature of this concept comes from the fact that the 400 mm frame size combines robust mechanics with a space-saving installation into existing machine assemblies. Thanks to the high power density, this three-phase motor 400/690 V is also suitable where the overhaul of the switchboard or the motor foundations must remain as short as possible. The rated torque of 2019 Nm gives the process a reserve during starting as well as during load changes, which helps to reduce unwanted downtime.

The rated current in delta connection at 400V reaches 1067 A and in star connection at 690V it is 618 A, so designers can adapt the motor to the supply without unnecessary compromises in the drive design. The starting ratio Tst/Tn 120% supports a smooth start-up of the technology, while Tmax/Tn 200% provides a mechanical reserve during short-term peaks. The starting current Ist/In 750% must be taken into account when coordinating with protection and switching elements, which is a common requirement for large industrial drives.

Multiple voltage levels for stable integration into operation

This design can also be sensibly matched to 380 V, 440 V, 500 V, 690 V and 720 V networks, because VYBO Electric designs it with the real conditions of modernisation and replacement of existing drives in mind. This solution makes deployment easier in operations with low-voltage infrastructure, where the replacement of an older machine often needs to be carried out without intervening in the entire energy system. Efficiency of 96.1% supports energy-saving electric motors in applications with a long annual operating time.

The power factor of 0.89 helps with power supply design and with estimating the overall network load, which is important in plants with several large consumers. Insulation class F together with temperature rise B creates a sensible thermal regime for operation in a demanding production line. The weight of 3500 kg indicates a massive construction that supports stability under mechanical stress as well as during long-term operation.

For European industry with an emphasis on reliable purchasing

Motors in the H17RL Compact PRO series are developed and manufactured specifically for European industry, especially for Western Europe, where emphasis is placed on service availability, compatibility and predictable service life. VYBO Electric is the largest company in its sector in Central Europe, which in practice is reflected in supply stability as well as technical support for long-term procurement. The modern design created using Hi-TECH technologies also supports precise drive behaviour in operation that works with no room for improvisation.

The standard equipment includes a steel cooling cover, reinforced bearings with steel shielding, high-temperature grease in the bearings, a metal terminal box and reinforced bearing shields. The rotor cage is designed as a massive aluminium cage, which contributes to durability under repeated loading. The DE 6220C3 bearing and the NDE 6220C3 bearing support long-term operation, which manufacturing plants expect from a drive in continuous service.

Accessories and operational supervision in demanding applications

The equipment includes PT100 sensors for the windings and bearings, an anti-condensation heater and a set of three PTC thermistors, so monitoring of the motor condition can be adapted to the needs of maintenance and the control system. The moment of inertia GD² 19,600 kg·m² and the external starting inertia of 206 kg·m² are important when designing starting, braking and coordination with the technological load. Such data will be appreciated by technology suppliers as well as industrial companies that modernise drives without unnecessary interference with the process.

In practice, this three-phase motor 400/690 V is used for centrifugal pumps in a chemical plant, blowers for a cement works, screw compressors in engineering production, heavy conveyor lines, mixers in the food industry, aggregate crushers, flue gas fans, rolling auxiliary units, utility water pumping stations and in gear systems for large cooling towers. Each of these applications uses the power reserve differently, but always with the same objective, which is reliable purchasing and long operational certainty.

If you need a drive for line modernisation or the replacement of existing equipment, H17RL Compact PRO offers a design ready for industrial deployment with an emphasis on service continuity. For a specific configuration, voltage version and delivery date, please request a quotation.
