Abstract

En elektrisk nedihullsmotor til en nedsenkbar pumpe har i det minste tre faser og omfatter en permanentmagnetrotor og en stator som bærer faseviklinger A, B, og C i spalter (2206) i statoren. Hver fasevikling A, B, C innbefatter en spole som strekker seg gjennom et respektivt par av innbyrdes tilstøtende statorspalter (2206) og omgir et respektivt parti av statoren mellom spaltene (2206). Dessuten strekker innbyrdes tilstøtende spoler i hvert par av faseviklinger A, B, C seg gjennom motsatte deler av én respektiv av spaltene (2206), slik at disse spoler strekker seg ved siden av hverandre i spalten, idet de enten er atskilt av et mellomrom som det kan pumpes kjølefluid igjennom for å kjøle spolene, eller er atskilt av et termisk ledende utspring (3110) som spolene er i termisk kontakt med, og som strekker seg i det minste et stykke på tvers av spalten. Et slikt viklingsarrangement er fordelaktig for å sikre at motoren har lang levetid.An electric downhole motor for a submersible pump has at least three stages and comprises a permanent magnet rotor and a stator carrying phase windings A, B, and C in slots (2206) in the stator. Each phase winding A, B, C includes a coil that extends through a respective pair of mutually adjacent stator slots (2206) and surrounds a respective portion of the stator between the slots (2206). In addition, mutually adjacent coils in each pair of phase windings A, B, C extend through opposite portions of one and each of the slots (2206), such that these coils extend side by side in the slot, being either separated by a space which it may be pumped through cooling fluid to cool the coils, or is separated by a thermally conductive projection (3110) with which the coils are in thermal contact and extending at least a distance across the slot. Such a winding arrangement is advantageous to ensure that the motor has a long service life.
