The position shutdown operating mechanism of the brush direct current motor receives, analyze and treat shutdown signals which are sent by the HALL sensor and the instruction module, when the magnet is close to the HALL sensor, the HALL sensor can achieve accurate shutdown positions of the motor according to the position of the magnet which is arranged on the motor rotating shaft.
Description
Technical field
Having the utility model relates to brush direct current machine field, specifically, is a kind of location shutdown operation mechanism that the brush direct current machine is arranged.
Background technology
DC motor have good speed adjustment features, starting easily, can the load-carrying starting etc. advantage, so the application of DC motor is still very extensive at present.Existing have the brush direct current machine in drive controlling, and motor stops from moving to, and the position that stops all is uncontrollable at random.
Because existing the brush direct current machine is arranged is to be parked in the optional position at random when shutting down; so when the user needs motor to stop in the fixing scope; just need the user after motor stops, manually stirring motor shaft to appointed positions; this wastes user's time and efforts very much, and operating efficiency is low.
If can invent a kind of operating mechanism, can be used for controlling the position that motor stops, thereby realize motor stop position accurately, just can solve the above-mentioned problem that always perplexs the user, also will be a very big contribution to the motor industry.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of location shutdown operation mechanism that the brush direct current machine is arranged is proposed; the signal that utilizes the controller receiving sensor to transmit; thereby stopping of control motor; realize motor stop position accurately, to solve the uncontrollable difficult problem of bringing to the user of stop position of motor in the prior art.
The utility model is achieved through the following technical solutions:
The location shutdown operation mechanism that the brush direct current machine is arranged; comprise magnet, HALL (Hall) transducer, controller; magnet is installed on the machine shaft and can does synchronous rotation with machine shaft; the HALL transducer is installed on the motor base, and machine shaft passes from the motor base middle part and do not contact, and is provided with CPU in the controller; CPU links to each other with the HALL transducer; CPU connects an operational order module, and CPU connects the Electric Machine Control driver, and the Electric Machine Control driver links to each other with machine shaft.
Described operational order module comprises instruction of control electric motor starting and motor halt instruction.
Described machine shaft is the external shaft of motor.
Described machine shaft is that motor passes through the bel-drivenn axle.
Operation principle of the present utility model: when magnet turns to machine shaft in the band of position of setting, because near the HALL transducer, the HALL transducer can produce a signal, the signal that the HALL of CPU reception at this moment transducer transmits, and carry out comprehensive analysis processing.When operating personnel need motor to stop; only need send a halt instruction to CPU by instruction module; after CPU receives signal; can send a stopping signal to the Electric Machine Control driver; simultaneously also can pass to the Electric Machine Control driver to the signal of HALL sensor passes after the comprehensive analysis processing; the Electric Machine Control driver receives can be controlled motor immediately behind two signals and stop, motor is stopped at exactly the mechanical location of signal correspondence.
Beneficial effect: the utility model has the location shutdown operation mechanism of brush direct current machine; by the stopping signal that CPU receives and analyzing and processing HALL transducer and instruction module transmit; the HALL transducer is according to the position that is installed in the magnet on the machine shaft; when magnet when the HALL transducer, can realize motor stop position exactly.
Description of drawings
Fig. 1 has the structural representation of the location shutdown operation mechanism of brush direct current machine for the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
Embodiment:
Referring to Fig. 1, as shown in the figure magnet 21 be installed on the machine shaft 12 and can with machine shaft 12 do synchronous rotation (the machine shaft here can for the external shaft of motor or for motor by the bel-drivenn axle), HALL transducer 22 is installed on the motor base 11, and machine shaft 12 passes from motor base 1 middle part and do not contact.
Be provided with CPU3 in the controller, CPU3 links to each other with HALL transducer 22, and receives the rate signal that is transmitted by HALL transducer 22.CPU3 connects an operational order module 4, and operational order module 4 comprises control electric motor starting and the signal that stops.CPU3 connects an Electric Machine Control driver 5, and CPU3 passes to Electric Machine Control driver 5 after the rate signal that receives is handled by analysis, and Electric Machine Control driver 5 links to each other with machine shaft 12, control motor startup and stop.
Fan-shaped dashed region among the figure is the band of position of setting in advance, when magnet 21 turns in the band of position of setting with machine shaft 12, because near HALL transducer 22, HALL transducer 22 can produce a signal, at this moment CPU3 receives the signal that HALL transducer 22 transmits, and carries out comprehensive analysis processing.When operating personnel need motor to stop; only need instruction module 4 to send a stop signal to CPU3; after CPU3 receives signal; can send a stopping signal to Electric Machine Control driver 5; also can pass to Electric Machine Control driver 5 to the signal that HALL transducer after the comprehensive analysis processing 22 transmits simultaneously; Electric Machine Control driver 5 can be controlled stopping of motor after receiving two signals immediately, motor is stopped at exactly the mechanical location of signal correspondence.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
