ASYNCHRONOUS ELECTRIC MOTORS

The company "RIMERA-ALNAS" produces standard and high-voltage asynchronous electric motors of size groups from 96 to 180 mm with a power from 12 to 750 kW with a speed control range of 2100 – 4200 rpm. High-voltage asynchronous electric motors are electric motors with increased supply voltage, which have a larger number of smaller conductors of the winding wire in the stator winding compared to standard EMs. Low operating current provides energy savings by reducing heat losses in the cable line. Applications • wells with a high content of solids • wells with a high gas content at the pump intake • wells with increased corrosiveness of the formation fluid • wells with a high temperature of the formation fluid • traditional wells Tech. specifications Characteristics and advantages: • manufacture of stators using PPI-U (M) winding wire with insulation from polyamide-fluoroplastic film "Kapton", "Apical" with heat resistance up to 200 ° C; • vacuum method of impregnating the stator with high-temperature varnish VS-346 or ELPLAST compound -180, 220; • the use of ENMAFLON fluoroplastic tubes as groove insulation of the stator; • the use of axial thrust bearings made of silicon carbide or with a PEEK coating; All threaded connections against the lapel use a sealant of the "Fixator -2.3" brand; • high-temperature version of the current lead elements: o made of PPS-A4 material with an operating temperature of up to 250 ° C; o made of PEEK material with an operating temperature of up to 300 ° C. heat-resistant rubber goods from mixtures resistant to synthetic oils: oRS-3, Ter-10 up to 220 ° C; oAF-15 up to 250 ° C.
