Electric motor 800 kW, 1488 rpm, 400 V / 690 V, H17RL 450X1-4 LV

The 1400-1500 rpm range is practical in this design for drives that must maintain stable performance even under variable load. The H17RL 450X1-4 model from VYBO Electric is designed to increase reliability in production operation while also supporting smooth connection to modern low-voltage systems. For technology suppliers and industrial companies dealing with drive modernisation, it is a solution with parameters suitable for demanding applications.

The 1400-1500 rpm range for processes with continuous load

At an output of 800 kW and a rated torque of 5134 Nm, the motor is used where smooth transmission of power without undesirable fluctuations is important. The rated current Delta 400V reaches 1367 A and the rated current Y 690V is 792 A, which gives designers room to choose a suitable connection according to the supply network. The 400 V / 690 V electric motor in this class helps in the design of drives for demanding applications, where starting conditions and long-term thermal load must also be taken into account.

Efficiency of 96.3% and power factor of 0.88 directly support energy-efficient operation in plants where every kilowatt hour affects operating costs. The ratio of starting torque Tst/Tn 110% and the ratio of breakdown torque Tmax/Tn 220% are suitable for processes that require sensitive starts without compromising operating behaviour. The ratio of starting current Ist/In 750% must be taken into account in the design, especially in networks where transformer and switchboard loading is monitored.

Strong cast-iron frame and adaptation to the environment

The strong cast-iron frame gives the construction a solid foundation and helps maintain accurate geometry even during long-term use in heavy industry. The IEC frame size 450 mm makes it easier to integrate into existing lines and at the same time opens space for adaptation to the environment, where IP56, IP65, IP66 or IP67 protection ratings are selected according to requirements. The electric motor for universal industrial applications therefore remains ready for a variety of operating conditions without unnecessary design compromises.

H17RL Compact PRO belongs to the Heavy Duty process performance class and is intended for operations that expect long-term load, frequent operation and precise response to process control. They are developed and manufactured specifically for European industry, especially for Western Europe, which is reflected in compatibility with local requirements for installation, maintenance and integration into existing assemblies. In Central Europe we are the largest company in our sector.

Design ready for service and longer operation

The standard specification 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 resistance. The DE bearing 6328C3 and the NDE bearing 6328C3 help maintain operating accuracy under continuous load, while the copper strip rotor cage supports robust behaviour during starting and in steady-state operation.

Temperature monitoring and operational safety

Monitoring efficiency is also increased by optional accessories, where thermal protection with 6x PT100 in the winding, PT100 in the DE and NDE bearing, anti-condensation heating and 3x PTC can be used. Insulation class F together with temperature rise B create a reserve for stable operation in production plants that deal with continuous duty and sensitive drive maintenance. The weight of 4900 kg and the external starting moment of inertia of 524 kg·m2 must be taken into account already at the design stage, as well as the moment of inertia GD2 52.0 kg·m2 when designing starts and control.

Typical industrial use without unnecessary compromises

• Pump drive in a chemical process water treatment plant.
• Main fan drive in a power block with regulated air flow.
• Conveyor drive in a quarry for loose aggregates.
• Extruder in a polymer processing line.
• Mill drive in cement plant technology.
• Pressing unit in metallurgical production.
• Compressor unit in industrial compressed air systems.
• Mixing equipment in a paper or pulp process.

For projects where technical discipline and service continuity are decisive, the H17RL 450X1-4 provides scope for reliable integration into a new line as well as for replacing an older drive. The 400 V / 690 V electric motor in this power range simplifies communication between design, maintenance and operations. After a technical consultation, send us an enquiry.
