How do ordinary motors achieve precise positioning
Because there is no position sensor, you can't locate it. If you need to locate, you can only use servo motor or excitation machine. Electric machinery is a kind of electromagnetic device that can be converted or transmitted by electromagnetic induction law. In the circuit, the letter M (old standard D) is used. Its main function is to generate drive torque as the power source of electrical or mechanical power. The generator is represented by the letter G in the circuit. Its main function is to use mechanical energy to convert into electricity, and the most commonly used is to use heat energy and water energy to push the rotor of the generator to generate electricity.
Ordinary motors can be accurately positioned through a series of circuits. Specific as follows: In action slider side low add a micro switch, micro switch control an intermediate relay, in the middle of the normally closed contact is broken the power of the motor, and at the same time delay relay through 3 s, the use of time relay normally open point back to the motor power supply. The highest point also can add a microdynamic switch the principle is the same! This completes the basic positioning control circuit and the lowest cost.
The action slider side low add a micro switch Using a micro switch control relay with relay contacts off the power supply of motor and at the same time delay relay through after 3 s With the time relay normally open point back to motor power supply. The highest point also can add a microdynamic switch the principle is the same! This is the cheapest way to do it!
