Electric motor 560 kW, 1485 rpm, 400 V / 690 V, H17RL 355X4-4 LV

When selecting a drive for production technology, it is sensible to opt for a solution that reduces the risk of unplanned downtime and keeps operation in a stable mode even under long-term load. The H17RL 355X4-4 model is designed in this respect to support higher reliability in production operation, especially where the 1400-1500 rpm range, industrial continuity and sensitivity to thermal and mechanical stress are concerned. In the VYBO Electric portfolio, it forms part of the professional range for modernisations, drive replacements and new installations in low-voltage networks.

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

The design of this machine is focused on high power density in a space that remains compatible with standard plant rooms as well as the refurbishment of existing lines. The rated output of 560 kW together with the rated speed of 1485 rpm creates a reserve for machines that require smooth transfer of energy without unnecessary oversizing. The rated torque of 3601 Nm supports heavier starts and steady operation in technological units where long-term load close to the rated values is expected. The power factor of 0.87 and efficiency of 96.3 % help keep operating losses under control, which is important in continuous operations and for every kilowatt hour that is worth using as effectively as possible. In practice, this is a 4-pole electric motor that suits drives requiring a stable operating point and a precise relationship between speed and load.

Electric motor 400 V / 690 V with adaptation to the environment

For designers and maintenance teams, the ability to adapt to the environment is important, which is why this electric motor 400 V / 690 V is supplied with optional protection according to the equipment conditions, including IP56, IP65, IP66 and IP67. Such a design simplifies deployment in dusty spaces, in damp environments, and in operations with increased requirements for protection of the electrical part. The rated current of 968 A at triangle 400 V and the rated current of 561 A at star 690 V allow flexible connection to the system according to the available infrastructure. The three-phase 400/690 V motor therefore fits better into modernisation projects where work with existing distribution systems is expected without unnecessary interventions in the whole technology. Industrial companies will also appreciate that the production configurations within the H17RL Compact PRO range are created with emphasis on the practical requirements of the European market, especially Western Europe.

Operational durability for heavy industry and modern drives

This electric motor belongs to the Heavy Duty process performance class, which is reflected in applications with high operating load, frequent starts and long cycles without interruption. The starting torque ratio of 120 % and the pull-out torque ratio of 200 % are designed to ensure that the drive can handle starting and transient states in demanding technological units. The starting current ratio of 700 % is part of the design and must be taken into account when sizing the starting equipment and protection. The rotor cage is designed as a solid aluminium cage, which contributes to durability during repeated starts and under higher mechanical stress. The weight of 3000 kg corresponds to a robust construction that is suitable for manufacturing plants, technology suppliers and operations with a high need for process certainty. From the point of view of integration, this is an advantage when refurbishing mixers, pumps, compressors and conveyors, where technical discipline is expected in every operating mode.

Standard equipment for long bearing life and cooling

The standard equipment includes a steel fan cover, which protects the cooling section from mechanical damage, reinforced bearings protected by a steel cover, high-temperature-resistant grease, a metal terminal box with a stronger design and reinforced bearing shields for greater mechanical resistance. The DE 6322C3 bearing and the NDE 6222C3 bearing are selected with regard to running stability under load and long-term service usability. Insulation class F and temperature rise B support operation in a mode where thermal reserve and controlled ageing of the winding are expected. The installation space is also made easier by the purposeful design of the terminal box, which meets the requirements of industrial assembly and service work. Combined with this package of elements, it creates a drive that is ready for long operation in technological units where reliable running and predictable service intervals are monitored.

A solution for production modernisation, energy efficiency and practical applications

When modernising drive units, it is often necessary to find a motor that will not complicate design or commissioning. That is why the H17RL Compact PRO is suitable for manufacturing plants, technology suppliers and industrial companies that are upgrading pumping stations, conveyor systems, fan units or mixing aggregates. Typical applications include:

• Pumps for circulation circuits in chemical production.
• Fans for process extraction in metallurgical operations.
• Conveyors in cement plants with long daily operating periods.
• Compressors in energy and engineering plants.
• Mixers in water treatment and wastewater treatment plants.
• Crushers and feeders in mining technology.

Energy-efficient electric motors from this range reduce operating losses especially where the year-round consumption balance and process stability are monitored. Development and production within VYBO Electric are focused on European industry, with ISO certificates also forming part of the credibility that confirm a systematic approach to quality. An output torque of 3601 Nm, an operating speed of 1485 rpm and the ability to operate on a 400 V / 690 V network create a combination suitable for long-term deployment in demanding operations.
