Generally, capacitance of a single phase motor is designed according to motor power, such as 1 kW dual value capacitance motor starting capacitance between 100uf and 200uf capacity.Operating capacitance is about 30uf. Single-phase motor is usually referred to as single phase AC power supply (AC220V

In order to meet the trend of miniaturization large capacity high reliability and low cost of electronic machine. Multilayer chip capacitor also develops rapidly: variety increases ceaselessly volume shrinks ceaselessly performance unceasingly improve technology unceasing progress material constantl

Depending on the capacity size of the electrolytic capacitor, commonly used multimeter's of R×10, R×100, R×1k.Red black table pen separately connects capacitor negative electrode (before each test) capacitor discharge) is determined by the deflection of table needle capacitor quality. If the needle

1. Gently rotating shafts with hands should feel smooth and should not feel sometimes loose tight or even stuck. When driving axis forward rear upper lower left and right direction the shaft should not loosen phenomenon. 2. Rotating shafts with one hand and touching the outer edges of the group ligh

Lots of theoretical researches and practices indicate that high speed circuits must be designed according to high frequency circuit. Capacitors used in high speed high density PCB require high frequency performance and small occupancy space. There are parasitic parameters in actual capacitors. Paras

Development Trend of capacitor applications (I)Capacitor is one of the basic components of electronic circuits, which has important and wide applications. According to classification, most capacitors are usually divided into four types: AC coupling, including bypass (AC DC); Decoupling (filtering al

4, aluminum electrolytic capacitor: it is made of aluminum cylinder as negative electrode, inside containing liquid electrolyte and inserted into a curved aluminum strip as positive electrode. It is characterized by large capacity, but large leakage, poor stability, positive and negative pole, suita

1,Ceramic capacitors: ceramic as a medium. The silver coating is sprayed on both sides of the ceramic substrate, and then the silver film is sintered as a polar plate. Its characteristics are: small volume, good heat resistance, small loss, high insulation resistance, but small capacity, suitable fo

Preventing harmonicsThere are many harmonic sources in the power network. If although the harmonic is too large at the node of the shunt capacitor, it is directly put into the shunt capacitor, it will often make the harmonic in the power network greater. It poses a great threat to the safety of shun

Strictly control operating voltageThe operating voltage of shunt capacitor must be strictly controlled within the allowable range. That is, the long-term operating voltage of shunt capacitor must not be greater than its rated voltage value of 10.If the operating voltage is too high, it will greatly
