Abstract
The utility model relates to a control circuit in the electric tool field, in particular to an electric hand drill speed regulation control circuit. The technical proposal is as follows: an alternating voltage regulation circuit consists of two controlled silicon T1 and T2 as well as an adjustable resistance R; a power switch K and the alternating voltage regulation circuit are connected in series in a power circuit of a motor DJ. The utility model which has a simple structure and convenient installation is arranged prior to the electric hand drill power or the adjustable resistance is linked with a switch. Therefore, the rotate speed of an electric drill can be adjusted at any moment, the purposes of safety and convenience as well as saving energy and protecting the motor are fulfilled, and the service life of the electric hand drill is prolonged as well.
Description
Technical field
The utility model relates to the control circuit of field of power tools, specifically is a kind of electric hand drill speed-regulating control circuit.
Background technology
Present interchange electric hand drill does not all have speed regulating device, needs armrest to move the continuous opening and closing motor power of console switch when some precision or dangerous situation use, to realize adjusting the purpose of motor speed.This adjustment mode both had been inconvenient to use, and also influenced the useful life of electric hand drill.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of electric hand drill speed-regulating control circuit of realizing electric hand drill stepless speed regulation is provided.
Its technical scheme is: form AC voltage adjusting circuit by controllable silicon T1, T2 and adjustable resistance R; Mains switch K and AC voltage adjusting circuit are series on the electric power loop of motor D J.
The utlity model has simple in structure, install additional conveniently; before being installed in the electric hand drill power supply,, can play the effect of adjusting the electric drill rotating speed at any time perhaps with adjustable resistance and switch gearing; play purpose safe, convenient, energy-conservation and the protection motor, prolong the useful life of electric hand drill simultaneously.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.IN uses the electric drill power input among the figure; DJ is the motor of electric hand drill.
Embodiment
Be further described with operation principle with regard to its circuit below in conjunction with accompanying drawing: the control utmost point of controllable silicon T1, T2 is connected adjustable resistance R and forms AC voltage adjusting circuit; Mains switch K and AC voltage adjusting circuit are series on the electric power loop of motor.Energized IN also turns on the power switch K, and the resistance that changes adjustable resistance R this moment can change the angle of flow of controllable silicon T1, T2, and the more little angle of flow of resistance is big more, and the rotating speed of electric drill motor D J is just high more; Otherwise the big more angle of flow of resistance is more little, and the rotating speed of electric drill motor D J is just low more.
Claims (1)
1. an electric hand drill speed-regulating control circuit is characterized in that: connect to form AC voltage adjusting circuit by controllable silicon (T1, T2) and adjustable resistance (R), and be connected on the electric power loop of mains switch (K) and motor (DJ).
