Description
Technical field
The present invention relates to electric motors, more particularly to a kind of electric machine control system.
Background technology
Motor is a kind of equipment for converting electrical current into mechanical energy.It is to use the power on coil to produce rotating excitation field and make
Electro-magnetic motor force rotation torque is formed for rotor.Motor is divided into current motor and ac motor by using power supply difference,
Motor major part in power system is alternating current generator, can be synchronous motor or asynchronous machine.Motor it is main by
Stator is constituted with rotor, and the direction of electrified wire movement under force in magnetic field is relevant with magnetic induction line direction with the sense of current.It is electronic
Machine operation principle is effect of the magnetic field to electric current stress, makes motor rotation.
Existing part motor needs rotating in routine use, is rotated forward in first half cycle, converts electrical energy into mechanical energy
Do manual work, when then the half period inverts, prior art is typically braked using braking resistor, the electric energy that reversion can be produced is in electricity
Resistance changes into heat energy and distributes, as shown in figure 1, including power supply 01, electric machine controller 02, motor 03, braking resistor 04, and invert
Electric energy is consumed by braking resistor and causes very big waste of energy, and electric energy utilization rate is low.
The content of the invention
The invention reside in the above-mentioned deficiency for overcoming prior art, there is provided a kind of can to save electric energy, electric energy utilization rate high
Electric machine control system.
In order to realize foregoing invention purpose, the technical solution adopted by the present invention is：
A kind of electric machine control system, including the first motor, the second motor, electric machine controller, power supply, described
One motor is respectively connected the electric machine controller, the power supply with second motor；The power supply electricity
Source is used to provide first motor, the second motor initial power, and first motor is used to drive the
One device works, and second motor is used to drive second device to work, and first motor drives with described second
Dynamic motor is connected by current bus bar, and the electric machine controller is used to control first motor to be operated in inverted status
When, the electric energy of generation is transferred to the second motor driving second device work or the second motor work is controlled
Make in inverted status, the electric energy of generation is transferred into first motor drives first device work.
Further, the power supply is additionally operable to the operation power according to the first motor, the second motor, to
First motor, the second motor carry out power compensation.
Further, first motor is opposite with the second motor operating phase.
Compared with prior art, beneficial effects of the present invention
Electric machine control system of the present invention is attached by by two motors by current bus bar, and shares an electric machine controller
It is controlled so that the electric energy produced during any one motor reversal can flow into another electricity for rotating forward by bus
Machine, power supply only needs to provide the motor normal work that certain compensation electric energy just can be rotated forward for this, and it can be high
Electric energy of the consumption in braking resistor when effect is inverted using motor, electric energy utilization rate is high.
Brief description of the drawings
Fig. 1 show the electric machine control system module frame chart of prior art.
Fig. 2 show electric machine control system module frame chart of the invention.
Specific embodiment
With reference to specific embodiment, the present invention is described in further detail.But this should not be interpreted as the present invention
The scope of above-mentioned theme is only limitted to following embodiment, and all technologies realized based on present invention belong to model of the invention
Enclose.
Embodiment 1：
Fig. 2 show electric machine control system module frame chart of the invention, including the first motor 1, the second motor 2, electricity
Machine controller 3, power supply 4, first motor 1 is respectively connected the motor control with second motor 2
Device processed 3, the power supply 4；The power supply 4 is used to provide first motor 1, the second motor 2 just
Beginning electric energy, first motor 1 is used to drive first device work 5 to make, and second motor 2 is used to drive second to fill
6 work are put, first motor 1 is connected with second motor 2 by current bus bar, the electric machine controller 3
During for controlling first motor 1 to be operated in inverted status, the electric energy of generation is transferred to second motor 2
When driving second device 6 to work or control second motor 2 to be operated in inverted status, the electric energy of generation is transferred to institute
Stating the first motor 1 drives first device 5 to work.
Electric machine control system of the present invention is attached by by two motors by current bus bar, and shares a motor control
Device processed is controlled so that the electric energy produced during any one motor reversal can flow into another and rotate forward by bus
Motor, power supply only needs to provide the motor normal work that certain compensation electric energy just can be rotated forward for this, and it can
Electric energy of the consumption in braking resistor when efficiently being 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
Effect power 3KW, now, power supply only need to targetedly compensate the loss of 2KW, 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 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.
Specific embodiment of the invention has been described in detail above in conjunction with accompanying drawing, but the present invention is not restricted to
Implementation method is stated, in the case of the spirit and scope for not departing from claims hereof, those skilled in the art can make
Go out various modifications or remodeling.
