Permanent magnet synchronous motor is common driving motor in electric car.Magneto has high power density and torque close
Degree, small in size, high-efficient, the good advantage of low-speed characteristic.In low speed, permanent magnet synchronous motor can provide big driving moment,
And its efficient region is mainly distributed near rated point, therefore permanent magnet synchronous motor also has very high operational efficiency in low speed,
There is good low-speed characteristic.But excitation is carried out using permanent magnet in permanent magnet synchronous motor, weak magnetic ability is limited, when driving electricity
When pressure saturation is needed through weak magnetic come raising speed, raising speed effect is often bad, or even has the risk for causing permanent magnet permanently to demagnetize.This
Outside, when motor operation is more than base speed, the decline of permanent magnet synchronous electric engine efficiency is very fast, and high speed performance is bad.
Induction machine is also common driving motor in electric car.Induction electromotor rotor uses squirrel-cage bar or winding-type knot
Structure.It is compared with permanent magnet synchronous motor, the weak magnetic of induction machine is easy to accomplish, and flux-weakening ratio is high, therefore induction machine is more same than permanent magnetism
Step motor has the broader range of speeds.In addition, with the raising of motor speed, the efficiency of induction machine declines more than base speed
It is slow compared with magneto, thus the high efficient district of induction machine is distributed near the above nominal torque point of base speed, induction machine is in high speed
Area efficiency is high, advantageous in high velocity.But induction machine takes the mode of electrical excitation to carry out excitation, power density and torque
Density is lower.And in low speed, induction machine efficiency is lower.
Therefore, used in the electric car for motor, permanent magnet synchronous motor and induction machine are all because respective
Defect and be difficult to meet the demand for having higher operational efficiency in the wide range of speeds.
Summary of the invention
Low speed cannot be combined the invention aims to solving driving motor used in existing electric car to turn greatly
The problem of operating status of square and high-speed high-power, provides a kind of hybrid modularization cascade electric system of permanent magnet induction.
The hybrid modularization of permanent magnet induction of the present invention cascades electric system, it includes a permanent magnet synchronous motors and one
Platform induction machine, it further includes two clutches,
The main shaft of permanent magnet synchronous motor is connected to form cascade form with the main shaft of induction machine, and every motor is correspondingly connected with
One clutch, two motors are identical as the form of clutch connection respectively；Clutch is mounted on each rotor inner surface
Between the outerface of spindle.
The clutch be unidirectional mechanical freewheel clutch, the unidirectional mechanical freewheel clutch include clutch stator, from
Clutch rotor and voussoir, clutch stator and rotor inner surface are cooperatively connected, and clutch rotor and the outerface of spindle cooperate
Connection is voussoir between clutch stator and clutch rotor；After the cascade of two motors, the rotation side that keeps two clutches locked
To identical.
Advantages of the present invention: the present invention combines permanent magnet synchronous motor and induction machine, respectively takes its chief.Every motor
Rotor and main shaft between be mounted with clutch, so that two motors is worked at the same time or is worked independently in this way.
Low speed permanent magnet synchronous motor and high-speed induction motor are coaxially cascaded into use, permanent magnet synchronous motor can be made full use of
The excellent high speed characteristics of excellent low-speed characteristic and induction machine；Permanent magnet synchronous motor and induction machine are due to there is different ginsengs
Number, therefore available special system external characteristics, make system have the characteristic of low speed high torque and high-speed high-power；By reasonable
Control strategy, the efficient region of system can expand, it is ensured that system has higher efficiency in the wide range of speeds；From
The use of clutch, so that being directly connected to the drawbacks of there is technical issues that between two motors and having obtained effective gram
Clothes, and when one of motor breaks down, another motor still can work, make system have preferable reliability and
Fault-tolerant ability.
