Description
HV HS induction is a high-voltage high-speed asynchronous motor for direct drive of compressors, which according to the manufacturer sets the availability standard in this class. The unique robust rotor with a short-circuit winding and a solid massive shaft provides exceptional reliability and long service life even at rotational speeds up to 16 000 rpm in the megawatt range. The motor runs only from a frequency converter and can be connected directly to a high-speed compressor without a gearbox, which minimizes the floor area and the number of mechanical assemblies. The power and speed range is from 2 MW at 16 000 rpm to 42 MW at 4800 rpm; the version is two-pole, and the supply voltage from the frequency converter is up to 13.8 kV. Cooling is provided by air-to-water or air-to-air heat exchangers or air ducts (IC86W, IC616, IC666, TEWAC, TEAAC, IC37), and the degree of protection is IP55. Explosion protection: increased safety Ex ec for zone 2, pressurization Ex pxb for zone 1, and Class I Division 2. The mass and dimensions are minimized, the stator is decoupled from the rotor, and very high efficiency and a wide speed control range practically without losses are achieved. Active magnetic bearings are available as an option for wear-free operation without oil. The motor is distinguished by minimal structural vibration, is suitable for any type of foundation and requires minimal maintenance. Its small dimensions make it optimal for replacing steam and gas turbines in existing plants, which reduces CO₂ emissions and increases efficiency. An example is the Repsol industrial complex in Puertollano (Spain), where replacing a steam turbine with an HV HS induction motor reduced CO₂ emissions by about 68 000 t per year and energy consumption by about 25 %. Applications are turbocompressors in refining and petrochemicals, gas transmission and booster compressor stations, LNG and underground gas storage.
