The inverter converts DC power (battery, storage battery) into AC power (usually 220V 50Hz sine or square wave). In general, an inverter is an electronic device that converts low voltage (12, 24, 48 volts, etc.) DC power into 220V AC (or other voltages) power. It consists of an inverter bridge, control logic and filter circuit. In daily life, 220 volt alternating current is usually rectified into direct current for use, and the inverter is the opposite. We are in an era of "mobile", mobile office, mobile communication, mobile leisure and mobile entertainment. In the mobile living state, not only the low-voltage direct current supplied by the battery or the battery is required, but also the alternating current which is indispensable in the daily environment. The inverter is to meet our needs.

When the brushed DC motor is working, the coil and the commutator rotate, but the magnetic steel and the carbon brush do not rotate. The alternating change of the current direction of the coil is accomplished by the commutator and the carbon brush that rotate with the motor. Compared with brushless motors, brushed motors have fewer wires, just one positive and one negative wire. If the BDC motor needs to be reversed, just switch the position of the two wires and it will be done.

The planetary geared motor is the same as other geared motors. It needs to be lubricated when it is running. This will not only speed up the operation of the planetary gear motor, but also ensure its normal operation. How to properly lubricate your planetary gear motors?
A pH electrode is a part of the pH meter contacting with a measured substance, it's usually used to measure the electrode potential. The service life of the pH electrode starts from the factory, regardless of whether it is used or not, the maximum service life is only 1 year, if the use and management methods are not in place, the service life will be shortened exponentially. This blog will tell you how to use, maintain, and storage pH electrodes.
If the cable drag chain cable is stretched by tension during wiring, it will friction with the inner wall of the drag chain and cause the sheath to wear. On the contrary, if the wiring is too loose, it will also cause friction with the inner wall of the drag chain, causing the sheath to wear, and it will easily be entangled with other cables. The wiring length of the drag chain cable should be set to just pass the center line of the drag chain. In addition, if the moving part of the drag chain cable is fixed, the bending stress will not be dispersed and absorbed. The fixed part of the cable should be set at both ends of the drag chain.
Impact wrench principle can be said to be "accomplish a great task with little effort by clever maneuvers", so it is commonly recognized and used in large-scale assembly and maintenance. However, impact wrenches are tools after all, and after long working hours or regular use, they will be damaged to different degrees, which requires us to have professional knowledge of repair and maintenance of wrenches.
In the automated production process, liquid level detection and monitoring has always played a more important role, such as the production of food and beverage, daily chemical products, pharmaceuticals, semiconductors and other industries, the cooling and lubrication of various machines, liquid level monitoring directly affects the quality of the product, and even related to the production process can be carried out smoothly.
The main function of a time relay is to act as an actuator in a simple program control, when it receives a start signal to start the timing, after the timing is over its operating contacts are opened or closed, thus driving the subsequent circuit work. Generally speaking, the time delay performance of a time relay is adjustable within the design range, thus making it easy to adjust the length of its delay time, so this article will tell you how to adjust time relay.
Impact wrench, also known as ratchet wrench and power tool in general, is mainly a tool that provides high torque output with minimal consumption. It accelerates an object with a certain mass by a continuous power source and then instantly slams into the output shaft, so that a relatively large torque output can be obtained.

The thyristor power controller adopts thyristor (SCR or TRIAC) as the switching component, namely, a non-contact switch that can quickly and accurately control the closing time. It serves as an essential terminal equipment for power control designed for high precision and high dynamic indicators. It is worth noting that different loads and constraints of the operation environment determine different control modes and require various supporting equipment. Among control modes there are phase angle control, distributed crossover and time proportional zero crossover. In actual use, SCR power controllers can be sorted into single-phase SCR power controllers and three-phase SCR power controllers in accordance with their load types, power supply types and power supply voltage levels. So, how should we choose the right type of power controller and bring its optimum performance into play with minimal damage? The following passages will give you the answer.
