Abstract

The invention provides a time-varying resistor, which comprises a rotating handle, a resistor body, a slide metal contact and a guide rod, wherein the axis of the rotating handle is connected with a first end of the guide rod, a second end of the guide rod is connected with the slide metal contact, and the slide metal contact is in electrical contact with the resistor body. The resistor also comprises a time-varying elastomer which is used for changing the position of the slide metal contact along time. According to the technical scheme, a balance spring can be used as an elastic element on the basis of the variable resistor, so that the output resistance of the resistor can be continuously and linearly adjusted along time, and the requirement on stable and safe operation of starting and speed adjusting of a motor in special places can be completely met.

Description

technical field [0001] The invention relates to the field of electronics and electrics, and is applied to the fields requiring the connected resistance to change with time, such as motor starting and speed regulation, electrical equipment used under severe environmental conditions, and the like. Background technique [0002] The resistance value of the variable resistor can be adjusted, and the resistance can be changed by changing the length of the resistance wire connected to the circuit part. Connecting variable resistors in the circuit can adjust the size of the current and the voltage division of the components in the circuit. The temperature of the electric iron, the brightness of the light, the volume of the speaker, the speed of starting the motor or controlling it, etc. are all connected in series with variable resistors in the circuit to achieve adjustment. [0003] A variable resistor consists of a resistive body and a turning or sliding system. On the exposed r...
