SUBMERSIBLE ELECTRIC MOTOR WITH PERMANENT MAGNETS

摘要

electrical engineering, electrical machine engineering, possibly production of oil and other stratum liquids. SUBSTANCE: electric motor includes stator with winding and salient-pole rotor with permanent magnets. Stator winding is flat slot-free one. It is laid in non-magnetic framework of slot-free block of stator with non-magnetic rings; said block is pressed-in to housing of electric motor. Method for making submersible electric motor with permanent magnets comprises steps of charging and pressing-in slot-free block of stator to housing of electric motor, placing flat slot-free winding of stator into non-magnetic framework arranged inside charged block of slot-free stator and mounting rotor with permanent magnets. EFFECT: enlarged functional possibilities of thyratron motor operating as submersible one, simplified technique for making winding of slot-free stator due to use of winding with framework. 2 cl, 4 dwg
