Embodiment
The present invention is further described below in conjunction with drawings and the specific embodiments.
A kind of intelligent motor controller as shown in Figure 1, be used to control motor just changeing the counter-rotating and speed carry out complete control, its structure comprises three-phase electricity input, inverter output terminal, motor band-type brake control end.
Motor is connected with frequency converter, and wherein 3 pin of frequency converter and 4 pin are the analog quantity input port, and 18 pin and 20 pin are the output signal port.
This device is as the VF1 among Fig. 1, and three-phase power line elder generation input converter outputs to motor from frequency converter again.The forward and reverse that 5 pin of device and 6 pin are controlled motor respectively, Y2 is used for the brake of motor band-type brake, so that motor stops operating, 3 pin of device and 4 pin are used for the analog quantity input, with the speed of control motor rotation, 18 pin and 20 pin of device are used for output signal, and whether the expression motor moves.
This controller is inserted in circuit for controlling motor, can control that motor just changes, reverses, starts, stops, the run signal of brake and output motor, thereby realize the intellectuality control of motor.
Wherein, main circuit of converter is the power converter part that the voltage regulation and frequency modulation power supply is provided to asynchronous motor.The main circuit of frequency converter can be divided into two classes substantially: 1, voltage-type is that the filtering of DC loop is electric capacity with the frequency converter of DC converting for exchanging of voltage source; 2, current mode, be the frequency converter of DC converting for exchanging with current source, its DC loop filtering is inductance, it is made of three parts, power frequency supply is transformed to " rectifier " of direct current power, be absorbed in " the flat ripple loop " of the mains ripple of current transformer and inverter generation, and " inverter " that direct current power be transformed to AC power.
(1) rectifier: a large amount of uses is the current transformer of diode recently, and it is transformed to DC power supply to power frequency supply.Also available two group transistor current transformers constitute reversible convertor, because its power direction is reversible, can carry out regeneration operating.
(2) flat ripple loop: in the direct voltage behind rectifier rectification, contain the pulsating voltage of power supply 6 overtones bands, the pulsating current that produces of inverter also makes the direct voltage change in addition.In order to suppress voltage fluctuation, adopt inductance and electric capacity to absorb pulsating voltage (electric current).Installed capacity hour has surplus if power supply and main circuit constitute device, can save inductance and adopt simple flat ripple loop.
(3) inverter: opposite with rectifier, inverter is the AC power that direct current power is transformed to the frequency that requires, and 6 switching device conductings of chien shih when determined, turn-offs and just can obtain 3 cross streams and export.
Control circuit is the loop that control signal is provided to the main circuit of asynchronous motor power supply (voltage, frequency adjustable); it has frequency, voltage " computing circuit "; " voltage, the current detection circuit " of main circuit; " velocity checking circuits " of motor; " drive circuit " that the control signal of computing circuit is amplified, and " protective circuit " of inverter and motor formed.
(1) computing circuit: instructions such as the speed of outside, torque are compared computing, output voltage, the frequency of decision inverter with electric current, the voltage signal of testing circuit.
(2) voltage, current detection circuit: detect voltage, electric current etc. with the major loop potential isolation.
(3) drive circuit: the circuit that drives the main circuit device.It and control circuit are isolated makes main circuit break-over of device, shutoff.
(4) velocity checking circuits: be contained in speed detector on the asynchronous motor machine (signal be rate signal, send into operational loop, according to instruction and computing motor is turned round by command speed.
(5) protective circuit: detect the voltage, electric current of main circuit etc.,, damage, inverter is quit work or suppress voltage, current value in order to prevent inverter and asynchronous motor when overload or overvoltage etc. taking place when unusual.
Device of the present invention efficiently solves the complexity problem of Electric Machine Control, can realize efficient various control stably of motor, boosts productivity, and brings more benefits to enterprise, is subjected to users' consistent favorable comment.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
