H17R 500-D-6-6 delivers high power density for drives that must provide 1400 kW in limited space while keeping operation under control. In the segment of large lines, a 900 rpm electric motor is often assessed by how it handles starting, thermal load and prolonged loading in continuous operation. This three-phase drive from VYBO Electric is designed to fit projects where full output is expected without compromises in the layout of the technology.
Compact 6000 V electric motor for 6 kV industrial drives
The compact solution in this model is based on a 500 mm frame, allowing the output class of the 6000 V electric motor to be integrated even where space in the machine room or drive hall is strictly limited. Such a concept simplifies the design of new assemblies and modernization of older units because the power reserve is transferred into a smaller footprint. For designers of 6 kV industrial drives, it is important that the motor remains suitable for applications with high requirements for continuity of operation and stable energy transmission.
A six-pole electric motor in this power class helps maintain a speed range suitable for pumps, fans and technological units with sensitive load dynamics. Rated torque of 13424 Nm provides reserve capacity for operating peaks, and rated current of 162,7 A creates predictable requirements for the power-supply system. Efficiency of 96,6 % and a power factor of 0,86 support economical operation during long production cycles where every kilowatt-hour affects the cost of the entire line.
Copper rotor for long service life under heavy load
The copper rotor made from copper strip reduces winding losses and at the same time better withstands thermal stress during repeated starts. This design is suitable for operations where the motor experiences frequent load changes, vibration and long hours at full duty. Temperature rise class B combined with insulation class F supports reliable operation in environments with high requirements for both electrical and thermal resistance.
For large process and power drives, feedback on machine condition is also decisive, so measuring and protective elements such as 6xPT100 in the winding, 1xPT100 in the NDE bearing, 1xPT100 in the DE bearing, an anti-condensation heater and a 3xPTC thermistor fit naturally into the assembly. Such equipment simplifies monitoring of thermal behaviour both during shutdowns and full operation. For the operator, this means better control over service intervals and a lower risk of unplanned intervention.
Special protection and stability for demanding industrial environments
In demanding environments, protection must reflect real conditions in the machine room, dusty hall or technological operations with higher humidity. The assembly can be supplied in IP56, IP65, IP66 or IP67 versions, allowing the motor to be adapted to the level of contamination and required protection. In practice, this is particularly valued in operations where resistance to dust and water ingress without limiting output is important.
Proven VYBO Electric solution for large operations
VYBO Electric has operated in industrial electrical engineering for years and applies its experience to solutions for heavy industry, the energy sector and large manufacturing units. The H17R 500-D-6-6 model is therefore based on a design that takes into account the requirements of both designers and maintenance teams while supporting long-term operational reliability. A 900 rpm electric motor at this output is used wherever not only output but also process stability and service predictability are monitored.
For various industrial applications, the motor is suitable for conveying systems, main pumping facilities, large fans, compressor assemblies, mills, agitators, crushers, extrusion lines, heavily loaded belt conveyors and drives for water-management technology. In such operations, the ability to maintain stable speed under prolonged load and handle starting without excessive wear of the mechanical section is particularly valued.
