Background technology
Present vehicula motor has only single mechanical property; The efficiency operation zone of motor is limited, can not satisfy the demand of efficient operation of low-speed big and high speed, high efficiency operation simultaneously, and adopts the electric motor system of mechanical type speed change; Parts are many; Complex structure, because of there being mechanical loss, system effectiveness is low.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides the brushless vehicula motor of a kind of double speed, this motor can satisfy low-speed big and efficiently move, and can satisfy the high-speed and high-efficiency operation again, and simple in structure, easy to use.
The present invention for the technical scheme that solves its technical problem and adopt is: the brushless vehicula motor of a kind of double speed; It is characterized in that: the stator coil of motor is divided into two groups; First group of coil and second group of coil; Other is provided with a controller and change over switch; Said controller can receive said motor rotating speed height signal and according to the said change over switch of this signal controlling, said change over switch can be controlled that said first group of coil and second group of coil are in first coil and second coil connect and be one of parallelly connected.Judge that when controller receives tach signal rotating speed is that controller control transformation switch makes first group of coil connect with second group of coil when high and low rotating speed switching point (being the connection in series-parallel transfer point of coil) is following, thereby satisfy the slow-speed of revolution, the high pulling torque of motor; When receiving tach signal, controller judges that rotating speed is when high low rotation speed switching point is above, first group of coil of controller control transformation switch and second group of coils from parallel connection of coils, thus satisfy the high-speed cruising of motor.The high and low rotating speed switching point can be provided with according to customer demand.On same stator,, first group of coil and second group of coil are connected and parallel connection through change over switch; Make motor have different mechanical properties; To satisfy the demand of different applying working conditions, effectively expanded the efficiency operation zone of motor, and more effectively utilized accumulator jar.
As further improvement of the present invention; Said stator coil is made up of first group of coil and second group of coil; Said first group of coil comprises three coils; Said second group of coil comprises three coils, three coils of said first group of coil an end be electrically connected with said controller respectively, the other end of three coils of said first group of coil is electrically connected with change over switch respectively; One end of three coils of said second group of coil is electrically connected with said change over switch respectively; The other end of three coils of said second group of coil is connected in a bit, and said change over switch is connected and is controlled by said controller with said controller, and said change over switch is one of electronic switch and mechanical switch; And this change over switch can make the end of three coils of the other end and second group of coil of three coils of said first group of coil couple together; Thereby realize being connected in series of first group of coil and second group of coil, and an end of three coils of said second group of coil is coupled together respectively at an end of three coils of said second group of coil, thereby realize being connected in parallel of first group of coil and second group of coil.
The invention has the beneficial effects as follows: make two groups of coils realize series connection when the motor low-speed running through controller; When running up, realize parallel connection, in the time of so not only can realizing motor low speed, efficient is high, output torque is big; Motor is turned round under the big twisting states of low speed; Satisfy electric motor car and will overcome the demand of the big load of low speed, and when the motor high speed, can satisfy the demand that electric high-speed goes again.
