Abstract
The invention relates to an asynchronous motor capable of automatically controlling steering, which can automatically control the steering of the motor during an operation process. An electronic switching circuit or a single chip microcomputer is used for programmably controlling small DC relays with conversion contacts to act, two input ports of the single chip microcomputer are connected with resistor-capacitor elements, the operation time can be automatically adjusted by the user, and the contacts of the relays are connected with ends of different windings of the motor respectively.
Description
Technical field
The present invention relates to a kind of asynchronous motor automatically controlling and turning to.
Background technology
The AC asynchronous motor of modern production, generally uses two-direction switch to change rotation direction.The contact of these manual two-direction switch, since it is desired that contact instability by very big electric current, it is easy to be burned out.The utility application of my Application No. 2016203539530, provides the two-direction switch of a kind of monophase machine using Miniature direct current relay to construct, and solves single-phase motor manual two-direction switch contact instability, the problem burning contact.
Content of the invention
The purpose of the present invention, it is simply that provide and a kind of can automatically control the asynchronous motor turning in running.
Realize the technical measures of the present invention, it is exactly to use electronic switching circuit or mcu programming, the action of the Miniature direct current relay with transfer contact for the control, the contact of relay connects the different end points of the different winding of motor respectively, it is achieved asynchronous motor running automatically controls the function turning to.
Use the action of electronic switching circuit control Miniature direct current relay, have too many background technology to select, only recommend a kind of mode using mcu programming to control Miniature direct current relay to realize the requirement that auto-controlled motor turns to here:
The action of the output control Miniature direct current relay of single-chip microcomputer, Resistor-Capacitor Unit (potentiometer can be used to substitute fixed resistance, in order to user adjusts the operation time voluntarily) is accessed in two input ports.
Brief description:
Fig. 1 is for using the circuit theory diagrams of the asynchronous motor automatic reversing apparatus of Single-chip Controlling Miniature direct current relay construction；
Fig. 2 is for using the relay contact wiring diagram of the monophase machine automatic reversing apparatus of Single-chip Controlling Miniature direct current relay construction；
In each figure, label symbol is as follows: DPJ is single-chip microcomputer；W is resistance or potentiometer in limited time；C is electric capacity；R is resistance；JZ1, JZ2, JZ3 are Miniature direct current relay；ZL is main winding；FL is auxiliary winding；～it is AC power symbol.
For simplifying explanation, figure eliminates the parts unrelated with content of the invention such as centrifugal switch, capacitor, terminal box and control power supply of monophase machine.
Detailed description of the invention:
Further describe the detailed description of the invention of the present invention below in conjunction with accompanying drawing:
Embodiment one: use an automatic reversing apparatus of the monophase machine of Single-chip Controlling Miniature direct current relay construction.Using the action of mcu programming three Miniature direct current relays of control, two input ports of single-chip microcomputer connect potentiometer and the delay circuit of electric capacity composition respectively.After powering on, first single-chip microcomputer starts JZ1 and JZ3, and drags down two input ports respectively, and motor forward runs；Then starting to read the state of the two input port, when the first input port level is upgraded to high level, control JZ1 release starts JZ2 simultaneously, motor changes inverted running into, after the second input port level is upgraded to high level, control relay all discharges, and completes once complete operation.
Embodiment two: use the repeatedly automatic reversing apparatus of the monophase machine of Single-chip Controlling Miniature direct current relay construction.Circuit structure is essentially identical with upper example, difference is that the second input port level is upgraded to the time that time of high level is upgraded to high level much larger than the first input port level, the time that memory changes while changing rotation direction for the first time, repeatedly to change the open/close states of JZ1 and JZ2, until end of run.
Embodiment three: use the three phase electric machine automatic reversing apparatus of Single-chip Controlling Miniature direct current relay construction.This example is only with two Miniature direct current relays, one phase power supply (such as A phase) is passed directly into a phase winding of motor, again normally opened point and the normally closed point of a relay, connect the normally closed point of another relay and normally opened point respectively, connect other two-phase power supply, other two phase windings of motor (transfer point of two relays connect respectively), just constitutes the automatic reversing apparatus of three phase electric machine.
Claims (1)
1. one kind automatically controls the asynchronous motor turning to, it is characterised in that: using electronic switching circuit or mcu programming, the action of the Miniature direct current relay with transfer contact for the control, the contact of relay connects the different end points of the different winding of motor respectively.
