Pulse motor or stepper motor step motors, foreign, or commonly known as Step motor Stepping motor, Stepper, and so on. To the conventional stepper motor, the stepper motor can be simply defined as, according to the input pulse signal, each time changing the excitation state to move forward at an angle (or length), if not change the excitation state is to maintain

a certain position at rest motor. Broadly speaking, the stepper motor is controlled by the electrical pulse signal brushless DC motor can also be seen as a certain frequency range and control of pulse frequency synchronous speed synchronous motor. Used here is the two-phase hybrid stepping motor, the use of displacement and the number of input pulse signals corresponding to step away from the characteristics of error is not accumulated to form the structure is simple and has a precision open-loop control system, the turret drive control system The operative part. Physical map shown in Figure 1 Rectifier board is used to rectify alternating current into direct current to provide the drive to use, the principle for the bridge rectifier circuit, the schematic shown in Figure 1 age, D2, D4 closed. Circuit constitutes e2, Dl, Rfz, D3 power circuit, the Rfz, formed under the negative on the positive half-wave voltage of the whole wash, e2 is the negative half-week, on D2, D4 plus the forward voltage, D2, D4 conduction; on D1, D3 reverse voltage, D1, D3 closed. Circuit constitutes e2, D2 Rfz, D4 power circuit, formed on the same is in Rfz the other under the negative half-wave rectifier voltage. Ball is relative to the original in terms of T-shaped screw th. The principle is the rotational variable translation, screw rotation. Ball screw driven slide the rod. Almost with the principle of the screw, but with the ball only. Turn the...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
