BRUSHLESS MOTOR Russian patent published in 2022 - IPC H02K1/18 H02K9/19 H02K5/167 H02K5/132 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the brushless motors, and can be used, for example, as an electric drive for submersible pumps. The electric motor contains a motor housing, a multi-section rotor with permanent magnets, a laminated multi-section stator with a magnetic circuit and phase windings. To fix the package of stator plates, rods are used in the amount of two or more, connected to the sleeves-clamps along the ends of the stator, which engage with the intermediate rotor supports. To fix the stator sections and supports in the axial direction and against rotation in the housing, an end element with a retractable lock is used. Fluid is forced into the bearings of the rotor sections.

EFFECT: improving the manufacturability of assembling a multi-section submersible electric motor, the durability and fault tolerance of the electric motor.
