A kind of electric machine control system, including the first motor, the second motor, electric machine controller, power supply, institute
State the first motor and be respectively connected the electric machine controller, the power supply with second motor；It is described to supply
Power supply is used to provide first motor, the second motor initial power, and first motor is used to drive
Dynamic first device work, second motor is used to drive second device to work, first motor and described the
Two motors are connected by current bus bar, and the electric machine controller is used to control first motor to be operated in reversion shape
During state, the electric energy of generation is transferred to the second motor driving second device work or second motor is controlled
When being operated in inverted status, the electric energy of generation is transferred to the first motor driving first device work.

Embodiment 1：
Fig. 2 show electric machine control system module frame chart of the present utility model, including the driving of the first motor 1, second
Motor 2, electric machine controller 3, power supply 4, first motor 1 are respectively connected institute with second motor 2
State electric machine controller 3, the power supply 4；The power supply 4 is used for first motor 1, the second motor
2 provide initial power, and first motor 1 is used to drive first device work 5 to make, and second motor 2 is used to drive
Dynamic second device 6 is worked, and first motor 1 is connected with second motor 2 by current bus bar, the motor
When controller 3 is used to control first motor 1 to be operated in inverted status, the electric energy of generation is transferred to described second and driven
When the dynamic driving of motor 2 second device 6 works or controlled second motor 2 be operated in inverted status, by the electric energy of generation
The driving of the first motor 1 first device 5 is transferred to work.
The utility model electric machine control system shares an electricity by the way that two motors are attached by current bus bar
Machine controller is controlled so that the electric energy produced during any one motor reversal can be flowed into another forward direction by bus and be turned
Dynamic motor, power supply only needs to provide the motor normal work that certain compensation electric energy just can be rotated forward for this, its
Electric energy of the consumption in braking resistor when efficiently can be inverted using motor, electric energy utilization rate is high.
The power supply 4 is additionally operable to the operation power according to the first motor 1, the second motor 2, to described
One motor 1, the second motor 2 carry out power compensation.
In an actual test, when the consumption of two powers of motor is 5KW, the electricity collection using reversion transmission is to having
Power 3KW is imitated, now, power supply only need to targetedly compensate 2KW loss, and specific loss balancing amount is according to practical application
Depending on.
In a detailed embodiment, first motor 1 and the operating phase phase of the second motor 2
Instead.When two motor working conditions are completely opposite, in reversion, just another motor is rotated forward one of motor, this
The electric energy that Shi Fanzhuan motors are produced just acts on positive rotating motor, compensation efficiency highest.
Embodiment of the present utility model is described in detail above in conjunction with accompanying drawing, but the utility model is not
It is limited to above-mentioned embodiment, in the case of the spirit and scope of claims hereof are not departed from, those skilled in the art
Member can be so that various modification can be adapted or remodeling.
