Abstract
The utility model discloses a kind of motor controller and its electric tool for being used to strengthen moment of torsion, including：Regulator block, solid-state relay and appearance inductive circuit, the rectangular wave that regulator block therein is used for trigger current export；Solid-state relay is connected with the regulator block, and the rectangular wave for the regulator block to be triggered is converted to forceful electric power；Excited by forceful electric power caused by the solid-state relay through the appearance inductive circuit, produce increase type moment of torsion.The utility model is by the way that motor controller is installed on electric tool, electric tool produces rectangular wave under locked rotor condition by regulator block, then rectangular wave is converted to by forceful electric power by solid-state relay again, electric power moment of torsion caused by forceful electric power is inputted to just in rotating motor by holding inductive circuit again, so that motor automatic driving-force adding breaks through obstruction, the normal smooth working of electric tool is kept, maintains the service efficiency of electric tool.
Description
Technical field
Power tools technology field used in a kind of construction site, such as electric wrench, chain stitch machine etc. are the utility model is related to, more
Specifically, it is related to a kind of motor controller and its electric tool for being used to strengthen moment of torsion automatically, occurs in electric tool stifled
When turning, it can be worked on by strengthening moment of torsion realization automatically.
Background technology
The electric tool used in construction site and the behaviour in service in workshop have very big difference, such as electric wrench, chain stitch machine
Deng since work status variation frequently encounters stall phenomenon, running into such case, experienced staff manually falls
Turn, then to beat again again, as charging again, make it break through obstruction.But work efficiency is not only so reduced, more
Serious meeting defective work piece, causes hidden danger of quality.
Utility model content
The purpose of this utility model is that solving the problems, such as existing electric tool stall, the normal operation of electric tool is realized,
For this reason, the utility model provides a kind of motor controller and its electric tool for being used to strengthen moment of torsion.
In order to solve the above technical problems, the utility model adopts the following technical solution：
On the one hand, the utility model provides a kind of motor controller for being used to strengthen moment of torsion, it is characterised in that bag
Include：
Regulator block, the rectangular wave for trigger current export；
Solid-state relay, is connected with the regulator block, and the rectangular wave for the regulator block to be triggered is converted to forceful electric power；
Hold inductive circuit, excited by forceful electric power caused by the solid-state relay through the appearance inductive circuit, produce increase type
Moment of torsion.
After motor stall current potential raises, the regulator block is reversed breakdown and produces rectangular wave.
On the other hand, the utility model additionally provides a kind of electric tool, including motor and electrical with the motor
The motor controller of connection, the motor controller are above-mentioned motor controller.
Increase type moment of torsion caused by the motor controller is more than caused maximum when the electric tool works
Stall moment of torsion.
Technical solutions of the utility model, have the following advantages that：
The utility model adds regulator block, solid-state relay and holds inductive circuit in the motor controller, works as motor
When there is stall, regulator block is reversed breakdown and produces rectangular wave, is then again converted to rectangular wave by force by solid-state relay
Electricity, then inputted electric power moment of torsion caused by forceful electric power to just in rotating motor by holding inductive circuit, so that motor
Automatic driving-force adding breaks through obstruction, keeps the normal smooth working of electric tool.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment, will make below to required in embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are some embodiments of the utility model, right
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
His attached drawing.
Fig. 1 is the control principle drawing of motor controller provided by the utility model；
Fig. 2 is to hold inductive circuit shown in Fig. 1.
Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, sheet
Field those of ordinary skill all other embodiments obtained without making creative work, belong to this practicality
Novel protected scope.
As shown in Figure 1, the utility model provides a kind of motor controller for being used to strengthen moment of torsion, including：
Regulator block, the rectangular wave for trigger current export；
Solid-state relay, is electrically connected with regulator block, for rectangular wave caused by regulator block to be converted to forceful electric power；
Hold inductive circuit, excited by forceful electric power caused by the solid-state relay through holding inductive circuit, produce increase type moment of torsion,
It is specific as shown in Figure 2.
After motor stall current potential raises, regulator block is reversed breakdown and produces rectangular wave.
The utility model can be automatic to strengthen the torque of motor in the case of operating personnel's incognizance obtains, and reinforces punching
Cross obstruction, it is not necessary to manually carry out any multioperation excessively.
The utility model possesses when electric current improves the potential change triggered, is triggered by regulator block and produces rectangular wave；Square
Shape ripple goes to forceful electric power by solid-state relay, then is excited by holding inductive circuit, and powerful electric power moment of torsion is input to and is also being continued
In rotating motor, motor high torque between stall can be made, so that held stationary operates.
For some electric tools, the motor of motor controller and electric tool need to be only electrically connected, you can real
The automatic adjustment of moment of torsion is now carried out to electric tool of the motor under locked rotor condition, makes increase caused by motor controller
Type moment of torsion is more than electric tool caused maximum stall moment of torsion at work, keeps rotating and breaks through obstacle rapidly, so as to protect
Hold the normal work of electric tool.
Above-mentioned disclosed regulator block and solid-state relay are the prior art.
Obviously, the above embodiments are merely examples for clarifying the description, and the restriction not to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the scope of protection of the utility model.
