SUBMERSIBLE PERMANENT-MAGNET MOTOR Russian patent published in 2005 - IPC

Abstract RU 2247463 C2

FIELD: electrical and electromechanical engineering.

SUBSTANCE: proposed permanent-magnet motor that can be used in production of submersible installations for extracting stratal liquids such as oil or water has stator and permanent-magnet rotor sections. Novelty is that rotor sections are built of laminated modules accommodating permanent magnets. Section modules are relatively shifted apart so that modules of preceding section are shifted from minimum to maximum and those of next section, from maximum to minimum, relative shift angle α being found from formula α = τ/n, where τ is slot pitch in degrees; n is number of modules.

EFFECT: enhanced reliability and economic efficiency of motor.
