220v single-phase capacitor start motor how to wiring

A. 220v single-phase capacitor motor wiring diagram example details: the motor in the factory has been done in accordance with the relevant standards of the wiring diagram, we only need to strictly in accordance with the wiring diagram of the correct wiring can be.

1. the motor's reverse switch diagram is as follows:

2. simple reverse wiring diagram is as follows:

2. 220V motor capacitor wiring diagram:

1. first two by two to measure the resistance of the three wires, remember the maximum value of the two wires and their resistance, the third line is the main and vice of the connection point;

2. measure the connection point and the ends of the resistance value (the difference between the two resistance values of the two). Resistance value (the sum of these two resistance values must be equal to the maximum value). The smaller resistance value is the main winding, the larger resistance value is the secondary winding. Generally for single-phase capacitor-start AC motors, the winding connector in series with the capacitor is the secondary winding.

3. Set the secondary winding resistance for R1, the main winding resistance for R2, then R1 "R2. (The main winding power, resistance is small.)

4. Comparison of the three terminals with a multimeter to measure the resistance between two terminals each time, the first to look for the firewire through the capacitor connected to the sub-winding connector terminals: its and the other two terminals between the resistance of the maximum value (R1 in series R2), and the second (Large value of R1) the remaining two terminals to find the smallest resistance R2 and the second small resistance R1 that is connected to the zero line terminal, that is, the main winding and the sub-winding of the public **** terminal.

5. If there is no problem with the motor, you can use a multimeter to measure the three wires, one of the wires and the other two wires are all through and through the resistance value of a larger a smaller, this line should be connected to the line on the zero line; measurement of the resistance of the smaller line should be connected to the line on the line on the fire wire (through the switch out of the connector) resistance of the larger one, the line should be connected to a capacitor. The line should be connected to a capacitor head, and capacitor head is connected to the fire line (that is, and the smaller resistance of the line and connected to the fire line), in accordance with this connection, and then according to the correct other wiring to connect the line, the power should be normal operation.

Expanded Information:

. p>A single-phase motor is generally a low-power single-phase asynchronous motor powered by a single-phase alternating current (AC220V). These motors usually have two-phase windings on the stator and an ordinary squirrel-cage rotor. The distribution of the two-phase windings on the stator and the different power supply conditions can produce different starting and operating characteristics. Because the 220V power supply is very convenient and economical, and family life with electricity are 220V, so single-phase motor not only in the production of a large amount, but also with people's daily lives, closely related, especially with the people's living standards are increasingly improved, the amount of single-phase motors for household appliances and equipment, but also more and more. Applied in the production of micro-pumps, grinders, threshing machines, pulverizers, woodworking machinery, medical equipment, etc., in terms of life, there are electric fans, hair dryers, exhaust fans, washing machines, refrigerators, etc., more varieties, but the power is smaller.
