H27R 5004-6-6 provides large industrial units with high energy efficiency, lower requirements for operating supervision and stable returns during long-term use. This 900 rpm electric motor with an output of 1600 kW and voltage of 6000 V is intended for applications where reliable power transmission, good thermal behavior and resistance to long-term loading are decisive. Thanks to a rated speed of 994 rpm, it is suitable for technologies that operate in steady-state mode and require a precisely defined operating point.
The H27R-HD-Modular series design uses a welded steel frame that provides high rigidity at a favorable weight and simplifies handling during transport and installation of large machines. The closed cooling circuit with IC611 air-to-air cooling helps keep the inside of the motor clean, which is important in dusty operations and environments with higher corrosive loads. The rotor cage made of copper strip supports low electrical losses, higher thermal resistance and long service life under repeated loads.
Operating cost savings with stable efficiency
High efficiency of 95,7 % and a power factor of 0,87 help reduce energy losses in continuous operation. This solution makes it easier to plan the power balance and size supply branches. In practice, this means less unnecessary heating, more favorable operating costs and better utilization of installed output over long technological cycles.
- Rated current of 185,5 A supports precise protection and connection design.
- Rated torque of 15372 Nm provides reserve for heavy starts and steady loads.
- Insulation class F together with temperature rise class B increases thermal reliability during operation.
- Package weight of 5880 kg reflects a robust design for large power drives.
Precise behavior during starting and network loading
When designing the starting system, the torque and current profile are also important. Starting torque reaches 1,1 times the rated torque, breakdown torque 2,2 times the rated torque and starting current 6,2 times the rated current, which facilitates sizing of protection, starting equipment and network reserve. For operators of large technologies, this is an important basis when coordinating with a transformer, soft starter or frequency converter if it is part of the system.
This three-phase electric motor is used where stable output, high voltage and reliable operation during long industrial cycles are required. As a high-voltage electric motor, it supports applications in the category of high-voltage industrial drives, where load resistance, good cooling and easier integration into existing electrical distribution systems are expected.
Use in heavy technology and power generation
H27R 5004-6-6 covers a wide range of applications in the process and power industries. It is used in drive units for refinery compressors, cooling- and process-water pumps, fans in power-generation units, exhaust fans, blowers for combustion and filtration lines, agitators in chemical production, crushers in mining, rolling units, auxiliary traction drives, ore conveyors, granulators, briquetting presses, raw-material grinding machines, large centrifugal separators and winding equipment in heavy industry.
Design solution for long-term operation
The NU238-C3+6040-C3 bearing arrangement on the DE side and NU230-C3 on the NDE side supports rotor stability under high load. Rotor inertia of 86,0 kg·m² and load inertia of 2040,0 kg·m² must be taken into account when designing starting, braking and mechanical linkage to the technological unit. The H27R 5004-6-6 model therefore provides a balanced solution for environments where long service life and low sensitivity to changes in ambient conditions are expected.
With the H27R-HD-Modular series, VYBO Electric combines robust mechanics, efficient cooling and parameters suitable for high outputs into a single unit prepared for industrial use without unnecessary compromises. For project departments, maintenance and purchasing alike, this 900 rpm electric motor is a solution that supports efficient operation, precise planning and high technology availability. To supplement technical documentation and order for your application, take advantage of the offer and choose a solution for reliable output in demanding operation.
