In order to improve operation performance of underwater vehicle anti-rotation propulsion system, a novel PMSM with Anti-rotation Dual rotor is proposed. It can be substantially simplify system structure, decrease volume and cost, moreover, improve reliability without brush and slip-ring. After the principles of operation, structure, and features are discussed, Design methodology is given. Both the...
A new type of PMSM with double rotors, used in underwater vehicle, makes the propulsion devices become simpler and more efficient. The structure of this motor is greatly different with the conventional ones, and the study of control strategy for this motor is on the primary stage. In this paper, the structure of the motor which is used in underwater vehicle system is introduced. To control the speed...
A novel PMSM with Anti-rotation Dual rotor is proposed in order to improve operation performance of underwater vehicle anti-rotation propulsion system. It can be substantially simplify system structure, decrease volume, reduce mass and cost, moreover, improve reliability without brush and slip-ring.

In view of the special structure of the novel PMSM with opposite-rotation dual rotors (ORDR) applied on the underwater vehicle counter-rotation propeller propulsion system, the mathematic model of ORDR machine was proposed. The magnetic-electric relationship based on equivalent magnetic loop and circuit was discussed. Through the simulations carried on the mathematic model, the influence on performance...
In order to improve operation performance of underwater vehicle counter-rotation propeller propulsion system, a new type of PMSM with opposite-rotation dual rotors (ODR) has been proposed. The principle of operation and magneto- electric models are discussed. The magnetic field generated by both rotors magnets is analyzed by MagNet software. The results prove that PMSM with ODR designed can produce...
