Description

Energy-saving electrical machine driving control device
Technical field
The utility model relates to electric motor energy-saving technique application, particularly a kind of energy-saving electrical machine driving control device.
Background technology
Electric automobile three-phase AC asynchronous motor is when middle light running, and because the capacity of carriage, load, road conditions, velocity variations are all very large, when intermittent duty and fluctuating load run, iron loss, copper loss are all very large, and efficiency and power factor are all very low.Cause very large energy waste, conventional control method such as direct torque control, vector control method all can not solve preferably.
Utility model content
The purpose of this utility model is to solve the problem, and devises a kind of energy-saving electrical machine driving control device.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of energy-saving electrical machine driving control device, comprise Electricmotor car wheel 1 and frequency converter 2, described Electricmotor car wheel 1 is provided with tachymeter 3, also comprise controller 4 and adjuster 5, described controller is connected with adjuster and frequency converter electrical equipment respectively, and described adjuster and tachymeter are electrically connected.
Described frequency converter is for connecting the drive motors of electric motor car, and described controller 4 adopts the mode of vector control by the output speed of the drive motors of Frequency Converter Control electric motor car.
Described adjuster 5 is the structures connected and composed successively by the filter 7 be fixed in housing 6, electric signal amplifier 8 and A/D converter 9.
Described filter 7 is electrically connected with tachymeter signal output part.
Described A/D converter 9 is electrically connected with the signal input part of controller.
The energy-saving electrical machine driving control device utilizing the technical solution of the utility model to make, by controller according to the mode of electric bicycle wheel speed to drive motors self adaptation vector control, adjust the input power of drive motors in real time, the voltage making motor obtain electric bicycle wheel speed instant with it to adapt most, thus ensure that motor runs all the time under maximum energy-saving state, thus effectively save valuable electric energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of energy-saving electrical machine driving control device described in the utility model;
In figure, 1, motor; 2, frequency converter; 3, tachymeter; 4, controller; 5, adjuster; 6, housing; 7, filter; 8, analog signal amplifier; 9; 10.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, as the structural representation that Fig. 1 is energy-saving electrical machine driving control device described in the utility model, as shown in the figure, a kind of energy-saving electrical machine driving control device, comprise Electricmotor car wheel 1 and frequency converter 2, described Electricmotor car wheel 1 is provided with tachymeter 3, also comprise controller 4 and adjuster 5, described controller is connected with adjuster and frequency converter electrical equipment respectively, and described adjuster and tachymeter are electrically connected.Wherein, described frequency converter is for connecting the drive motors of electric motor car, and described controller 4 adopts the mode of vector control by the output speed of the drive motors of Frequency Converter Control electric motor car; Described adjuster 5 is the structures connected and composed successively by the filter 7 be fixed in housing 6, electric signal amplifier 8 and A/D converter 9; Described filter 7 is electrically connected with tachymeter signal output part; Described A/D converter 9 is electrically connected with the signal input part of controller.
The feature of the technical program arranges tachymeter on the output shaft of motor, the size of electric bicycle wheel speed is monitored by tachymeter, and the signal real-time monitored is transferred to controller by adjuster, described controller passes through the rotating speed of Frequency Converter Control driving motor of electric vehicle by the mode of vector control, and then adjust the input power of drive motors in real time, the voltage making motor obtain load instant with it to adapt most, reduce electric energy loss, improve the utilance of electric energy, extend the useful life of motor.
In the technical program, controller detects the size of electric bicycle wheel speed by tachymeter, thus adjusts the frequency and voltage of drive motors in real time according to the size of electric bicycle wheel speed, controls the rotating speed of drive motors output shaft.
In the technical program, be converted into Electricmotor car wheel to the electrical power of drive motors input and rotate the machinery needed and exert oneself and loss two parts of motor self.The loss of drive motors self is damaged by the machinery of " iron loss " of magnet, " copper loss " of wire and bearing friction, fan again and is formed.Controller detects the change of Electricmotor car wheel rotational speed rate by tachymeter, according to the actual demand of load, adjusts power input to a machine in real time, ensures that motor runs under the power save mode of minimum current and optimum voltage.Current of electric and minimizing of voltage just can make the “ Tie Damage of motor self " and " copper loss " reduce to minimum, realize reducing the heating of motor while energy-saving run, and greatly extend the useful life of motor.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection range of the present utility model.
