Higher energy efficiency in large drives begins where the system needs stable output without unnecessary losses. H27R 5604-8-6 is a 700 rpm electric motor for demanding operations with an output of 2000 kW and voltage of 6000 V, designed for long-term economical operation under high load. In the HV electric motor category, it provides a combination of high efficiency, robust construction and operational reliability required by large factories and power units.
IE4 efficiency reduces losses during continuous operation
Motors in the H27R-HD-Modular series use IE4 Super Premium efficiency, which helps limit energy losses in high-power drives and supports economical continuous operation. At a rated speed of 744 rpm, rated current of 235,8 A and a power factor of 0,85, the operator receives a solution that can better manage electricity costs and the thermal load of the entire drive. This three-phase electric motor is therefore suitable where not only output but also long-term production efficiency is monitored.
Torque reserve is also important in high-power drives. Rated torque reaches 25672 Nm, starting torque is 0,75 times the rated torque and breakdown torque 1,8 times the rated torque. Starting current is 4,9 times the rated current, so the design of the power supply, switching and protection can be adapted to the specific process with regard to network load and the required starting dynamics. In practice, this facilitates integration into heavy-duty operations where stability and predictable starting behavior are decisive.
Welded steel frame facilitates installation of large motors
The motor design uses a welded steel frame that provides high rigidity at a more favorable weight than cast-iron solutions. With a package weight of 8250 kg, the operation therefore has greater control over handling, transport and placement on the foundation. A shaft height of 560 mm supports use in robust drive systems where firm support is needed for long-term mechanical stability. For such applications, this is a practical benefit, not merely a design detail.
H27R 5604-8-6 is also an eight-pole electric motor, making it well suited to technologies requiring lower speeds and high torque without unnecessary gearing compromise. Rotor inertia of 207,0 kg·m² and load inertia of 4310,0 kg·m² provide important inputs when sizing starting, braking and the mechanical connection between the motor and load. For large process lines, this is essential when assessing the dynamics of the entire system.
Standard thermal protection and monitoring increase operational reliability
H27R-HD-Modular motors are equipped with standard thermal protection and monitoring that help track the condition of the winding and bearings during operation. The stator winding is impregnated using VPI technology, and insulation class F together with temperature rise class B provides reserve for reliable operation under heavily loaded conditions. Additional PT100 sensors, PTC thermistors and anti-condensation heating support protection during shutdowns, starts and environmental fluctuations.
This type of solution performs well in technologies where long service life and precise monitoring of operating conditions are expected. This makes the 700 rpm electric motor easier to integrate into applications with high requirements for availability, service readiness and investment protection. In high-power drives, it therefore creates room for stable operation without unnecessary outages.
Use in heavy industry and power generation
H27R 5604-8-6 is intended for demanding applications combining high output, continuous load and a requirement for reliable operation. It is suitable for:
- Main pumps in power-generation and water-management units.
- Fans for combustion and filtration systems in large manufacturing plants.
- Compressor units in the process industry.
- Crushers and mills in cement plants.
- Rolling drives in metallurgical production.
- Extruders and mixing lines in the chemical industry.
- Extraction and mining conveyors in mines and quarries.
- Process-water pumps in refineries.
- Drives for drying and cooling drums in processing lines.
- Large homogenization and mixing equipment in the paper and pulp industry.
For operations requiring a combination of output, efficiency and robust mechanics, H27R 5604-8-6 provides a reliable basis for long-term deployment. If you need to assess suitability for a specific technology, contact us.
Why this model is suitable for long-term investments
With the H27R-HD-Modular series, VYBO Electric combines high efficiency, mechanical rigidity and control of thermal stress in a solution designed with total operating costs in mind. Rated output characteristics, stable speed and precisely defined parameters of DE bearing NU238-C3+6040-C3 and NDE bearing NU230-C3 are important when designing service intervals and planning maintenance. For the operator, this means a motor prepared for demanding conditions while supporting long-term availability of the technology.
