Problems solved by technology

This structure naturally forms the single function of the motor, that is, the power generation function or the load function; when it is used in electric vehicles, frequent charging is required, and the charging time is long, which is the biggest obstacle to the development and promotion of electric vehicles; Energy is limited, and the cruising range of one energy storage is hoped to be as long as possible, so it is also hoped that the driving motor can save energy to the maximum extent.
However, the existing permanent magnet brushless DC motor structure is difficult to achieve all the above functions
[0004] The charging function needs to be undertaken by a separate charger (station). For the large-scale development of electric vehicles, numerous charging stations need to be established, which not only requires a large amount of money, but also brings great inconvenience to the charging of electric vehicles.

Embodiment Construction

[0022] figure 1 Among them, there are two sets of windings A (3) and B (5) in the double-winding permanent magnet brushless DC motor (4), and the two windings are controlled by two independent controllers, the winding A controller inverter bridge (2) and the winding B controller inverter bridge (6) are controlled separately. In the double-winding permanent magnet brushless DC motor (4), there are two sets of windings A (3) and windings B (5) that are symmetrical to each other. At this time, the back EMF constitutes 30 ° A commutated winding.

[0023] When the electric car is running normally, the two sets of windings can run independently or at the same time. When the electric car stops, it is connected to the mains, one of which runs in the form of a motor, and the other set of windings runs in the form of a generator, supplying power to the battery (1) internal charge.

[0024] figure 2 Among them, winding A off-line (7) and winding B off-line (8) are single-phase off-li...

Abstract

The invention discloses a dual-three-phase bisymmetric winding permanent-magnet brushless direct-current motor. In the dual-three-phase bisymmetric winding permanent-magnet brushless direct-current motor, two permanent-magnet brushless direct-current motors are designed to share a rotor and a stator: 1, the two permanent-magnet brushless direct-current motors are designed as a special structure which shares the rotor and the stator; and 2, a self-charging function is realized by using the double winding permanent-magnet brushless direct-current motors which drive an electric vehicle. Namely, one motor winding is operated with no load by utilizing a motor winding when a vehicle parks; and the other motor winding forms a generator to realize a charging function, so that the charging function is singly realized when the motor is not operated.

Description

[0001] Field [0002] The invention belongs to a motor, in particular two permanent magnet brushless direct current motors are designed as a double-winding permanent magnet brushless direct current motor sharing one rotor and stator. Background technique [0003] The known permanent magnet brushless DC motors all have the structure of a rotor and a stator, and a stator has a group of coils. This structure naturally forms the single function of the motor, that is, the power generation function or the load function; when it is used in electric vehicles, frequent charging is required, and the charging time is long, which is the biggest obstacle to the development and promotion of electric vehicles; Energy is limited, and the cruising range of primary energy storage is expected to be as long as possible, so it is also hoped that the drive motor can save energy to the maximum extent. However, the existing permanent magnet brushless DC motor structure is difficult to realize all th...
