H17RL 400X2-8 is an 8-pole electric motor designed for energy efficiency in continuous industrial operation. In practice, it helps keep consumption under control even where stable torque, smooth starting and long service intervals are expected from the drive.
Energy efficiency in high-load operations
For large factories and OEM assemblies, not only power matters, but also how the motor performs during long production cycles. This three-phase electric motor is ready for use in lines where operating reliability, lower energy consumption and consistent performance at rated speed are monitored.
Robust cast-iron construction for long service life
The robust cast-iron frame supports mechanical resistance to vibration, during installation in technological systems and under more demanding starting conditions. Combined with a weight of 3560 kg, it creates a foundation that effectively dampens operating stresses and helps maintain drive stability under harsh conditions.
- Suitable for crushing and grinding sections where reliable engagement is important.
- Suitable for mixing equipment that runs in long batches.
- Supports continuous operation of conveyor systems in large plants.
- Suitable for pumping technology for process water and technological media.
- Can be used in fans for extraction and air-handling systems.
- Suitable for drives in compressor stations with demanding duty cycles.
- Suitable for mixers in the chemical and food industries.
- Helps drive extruders and pressing lines in material processing.
- Used in rolling and feed mechanisms.
- Performs well in separators and sorting equipment.
- Suitable for winding and unwinding stations in production technology.
- Used in belt conveyors in warehouses with high material throughput.
- Suitable for driving granulators and cutters in plastics processing.
- Supports the operation of homogenisers and dispersion units.
- It can also be used in technological systems with variable loads and high operating demands.
Compact output with a 400 mm shaft height
Thanks to its 400 mm shaft height, this low-voltage electric motor offers output that can be sensibly integrated into large machine assemblies without unnecessary space requirements. This makes the work of designers and maintenance teams easier when designing a drive where the ratio of output, space and service accessibility is decisive.
Choice of frequency for flexible drive design
For projects implemented in different markets, the ability to adapt the motor to the operating mains is important. This version can also be used for 60 Hz, simplifying the standardisation of assemblies in international manufacturing plants and reducing the need for design compromises.
Proven manufacturer and distributor VYBO Electric
The motor is supplied by VYBO Electric as a proven manufacturer and distributor, which is important for industrial purchasing when planning deliveries and standardising spare parts. Accessories are also available, including 6 x PT100 in the winding, 1 x PT100 in the NDE bearing, 1 x PT100 in the DE bearing, an anti-condensation heater and 3 x PTC thermistor, so diagnostics and temperature monitoring remain under control.
If you need a drive for demanding technologies, H17RL 400X2-8 provides a reliable foundation for long-term operation. Order it in time while it is available for your project and service schedules.
