Abstract
The utility model relates to a non-contact potentiometer. The utility model is composed of a sensing system and a circuit analysis and transition system, wherein, the sensing system is composed of an induction coil and an induction body, the induction coil is a solenoid coil, the induction body is a magnetizer, the induction body is close to the induction coil, and the relative position between the induction body and the induction coil can be controlled and moved. The relative position between the induction body and the induction coil is controlled to reach the purpose of adjusting the electrical potential, and the utility model is a non-attrition potentiometer, and is suitable for the industries in which the speed of the motor and the electric sewing machine is required to be frequently adjusted..
Description
Affiliated technical field
The utility model relates to the novel potentiometer of a kind of non-contact type.
Background technology
The potentiometer that uses is generally the contact potentiometer at present, is made of resistive film and contact, directly regulates residing position on resistive film, contact, the size of adjustable resistance, thereby the height of adjustment current potential.Because the contact rubs with frequent the contact with direct between the resistive film, causes the wearing and tearing and the scratch of resistive film, makes the potentiometer life-span not long.Improvement to potentiometer mainly is to come protective resistance film or contact by increase the conductive protection device between resistive film and contact at present; thereby reach the purpose that prolongs the potentiometer life-span, do not cause not long problem of life-span because of damage by friction but fundamentally solve potentiometer.
Summary of the invention
For overcoming potentiometer shortcoming easy to wear, the utility model provides a kind of contactless potentiometer, and it makes it to produce different inductance by the induction coil of adjusting sensor-based system and the relative position between the inductor, convert different current potentials to, reach the purpose of adjusting current potential.
For achieving the above object, the technical scheme that is adopted is: the utility model is made of sensor-based system and circuit analysis converting system, its sensor-based system is made up of induction coil and inductor, induction coil be one by the close solenoid coil that forms on the bobbin of insulated conductor, inductor is a magnetic conductor, inductor is near induction coil, and the relative position between inductor and the induction coil can be handled mobile.Adjust the relative position between inductor and the induction coil, can produce different inductance in the induction coil, variation inductance is drawn lead by induction coil and is reflected to the circuit analysis converting system, and is converted to the variation of current potential by converting system.Therefore, by adjusting the relative position between inductor and the induction coil, just can reach the purpose of adjusting the current potential height.
The beneficial effects of the utility model are, thoroughly eliminate the wearing and tearing of potentiometer, are that a kind of nothing wearing and tearing current potential is adjusted instrument, are fit to the equipment such as motor, electric sewing machine of the frequent speed governing of needs.
Description of drawings

1. inductive rod, 2. induction coils, 3. leads, 4. bobbins 5. are drawn lead among the figure
Embodiment
Fig. 1 is a potentiometer sensor-based system that is used for electric machine speed regulation, it is to be made of induction coil 2 and inductive rod 1, induction coil 2 be one by the close solenoid coil that forms on the bobbin 4 of insulated conductor 3, inductive rod 1 is the iron staff of an external diameter less than bobbin 4 internal diameters, one end of inductive rod 1 is through in the bobbin 4 of induction coil 2, the other end links to each other with operating control mechanism, operating control mechanism firmly, pulling inductive rod 1, inductive rod 1 produces relative displacement in induction coil 2, the physical length that inductive rod 1 is in the induction coil 2 changes, the inductance that produces in the induction coil 2 can change, lead 5 and circuit analysis converting system that induction coil 2 is drawn are joined, by analyzing the variation that converting system converts variation inductance to current potential, thereby be through length in the induction coil 2 by handling inductive rod 1, reach the height of adjusting current potential, finally reach the switch and the velocity of rotation of control motor.
