Electric motor 500 kW, 1485 rpm, 400/690 V, H17RL 355X3-4

H17RL 355X3-4 delivers high power density for technologies where space, torque and reliable starting under long-term load are decisive. This 1400 rpm electric motor from VYBO Electric is designed for demanding operations where stable running, precise connection to the transmission and sensible reserve capacity for production peaks are expected from the machine.

Robust cast-iron construction helps damp vibrations and keeps the motor mechanically stable even during continuous operation. Operators of large factories appreciate that an asynchronous electric motor designed this way tolerates loads better in pumps, compressors and conveyor-line drives.

1400 rpm electric motor for production continuity and precise integration with the technology

A rated speed of 1485 rpm provides a suitable compromise between speed and torque, which is important in drives with long duty cycles. From an integration perspective, this is an asynchronous electric motor with a squirrel-cage rotor that performs well where OEM manufacturers need predictable behaviour both during starting and under steady load.

In practice, it can be used in mixing lines, crushers, granulators, extruders, belt conveyors, roller mills, extraction fans, blowers, process pumps, cooling towers, winding equipment, presses, separators, dryers, screw conveyors and industrial mixer drives. Such applications require three-phase electric motors capable of repeated starts without unnecessary parameter fluctuations.

Robust cast-iron frame for mechanical durability in continuous operation

The main benefit of this solution lies in mechanical reliability. The cast-iron body better withstands stresses during installation, vibration transferred from the technology and operation in an extensive production environment where the motor is exposed to dust, thermal cycling and long running hours.

• Stable motor mounting reduces the risk of unwanted resonances throughout the drive.
• The heavy-duty construction supports long service life under continuous load.
• The design is suitable for production lines where service shutdowns are planned well in advance.

Compact output in IEC frame size 355 mm for large technological systems

When designing machines, the amount of active power that can fit into the installation space also matters. This motor therefore delivers compact output that simplifies integration into enclosed frames, modular machines and customised assemblies with limited installation space. For manufacturers of technological systems, this is a practical advantage when designing bases, covers and service access.

This also makes the 1400 rpm electric motor suitable where high power density is required without unnecessarily increasing the size of the entire drive. This approach is appreciated by companies standardising their units across multiple manufacturing plants.

Choice of efficiency class according to the plant’s energy strategy

VYBO Electric offers this asynchronous electric motor in different efficiency levels so it can be aligned with operating requirements, the investment plan and the required return. When modernising production lines or developing new OEM assemblies, this is particularly important where energy consumption is monitored over the entire equipment life cycle.

• Lower consumption under normal load supports control of operating costs.
• Choosing the appropriate efficiency makes standardisation across different machine types easier.
• The technical department gains greater flexibility when designing for variable production profiles.

Thousands of satisfied VYBO Electric customers particularly value the model for its consistent performance under real industrial conditions. Rated torque of 3215 Nm, a power factor of 0,87 and efficiency of 96,3 % are values that help when sizing the drive for long operating periods without the need for constant design compromises.

Predictable maintenance is also important for installation and service teams. DE bearing 6322C3 and NDE bearing 6222C3 support stable rotor operation, while the weight of 2800 kg corresponds to robust construction intended for industrial use with higher requirements for overall stability. H17RL 355X3-4 therefore fits projects where service life, reliability and technical reserve are considered within one solution.

For drive design in metallurgical lines, paper mills, cement plants, waterworks, refineries and heavy process manufacturing, it is important that the motor can be connected directly to robust technological systems without requiring disproportionately complicated integration. A starting torque ratio of 140 % and a breakdown torque ratio of 200 % help during starting, which is important for equipment with higher inertia.

Rated current △ 400V 864 A and rated current Y 690V 501 A are also important for precise sizing of the electrical installation. Combined with external starting inertia of 328,000 kg·m² and a GD² moment of inertia of 29,600 kg·m², the designer gains data that simplifies design of the starting regime under real operating conditions.
