Single phase dual value capacitor starting motor problem, high finger teaching!

The motor is easy to burn out in the case of overload, and the running capacitor is generally not easy to be damaged. The main winding can not be smaller than the secondary winding wire diameter (however, the motor of the washing machine, the main and auxiliary winding wire diameter is the same size) The increase in the operating capacitance will directly affect the constant power of the motor, the capacitance exceeds the constant value, the current of the motor will increase, and the motor will be burned out if the constant current is exceeded, and the operating capacitance is smaller than the constant value, which will reduce the working power of the motor.

1) The reasons for the burning of the single-phase dual-value capacitor starter motor are: overload, capacitor capacity drop and centrifugal switch damage.

2) The operating capacitor is generally reduced in capacity and burned out very little.

3) The main winding is thinner than the secondary winding line: the motor of the water pipe twisting machine.

4) The capacitance capacity is too large, the motor current is large, and the temperature rises quickly; The capacitor capacity is small, and the motor starts slowly.

The above is personal experience only.

There will be many reasons for the motor to burn up, low voltage, high voltage, overpower, etc., the capacitor will not burn generally, unless the capacitor withstand voltage you choose is not enough (such as 220V voltage, the capacitor withstand voltage should be 450VAC), the main winding is basically not thinner than the secondary winding line, the motor of the washing machine is not divided into the main and auxiliary wires, because they are both the main winding and the secondary winding, depending on the steering, the size of the running capacitor must be suitable for the performance of the motor, and the starting capacitor is the same. It's not good to start with a large starting capacitor.

I hope mine, you can be satisfied: the motor is easy to burn out in the case of overload, and the running capacitor is generally not easy to damage. The main winding can not be smaller than the secondary winding wire diameter (however, the motor of the washing machine, the main and auxiliary winding wire diameter is the same size) The increase in the operating capacitance will directly affect the constant power of the motor, the capacitance exceeds the constant value, the current of the motor will increase, and the motor will be burned out if the constant current is exceeded, and the operating capacitance is smaller than the constant value, which will reduce the working power of the motor.

Friend, the starting capacitance of a general single-phase motor is about 150uf to 400uf. The operating capacitance, that is, the working capacitance, is generally to about .

Generally, the starting capacitance is 200uf, and the motor is about 20uf when running!

The starting capacitance value is much larger than the operating capacitance value.

The starting capacitance value is much larger than the operating capacitance value. Generally, the starting capacitance is 200uf, and the motor is about 20uf when running!

Single-phase motor generally refers to a low-power single-phase asynchronous motor powered by a single-phase AC power supply (AC220V). This type of motor usually has a two-phase winding on the stator, and the rotor is a normal squirrel cage type. The distribution of the two-phase windings on the stator and the power supply can produce different starting and running characteristics.

Friend, it depends on the size of your motor

Summary. Hello dear ! The 220V single-phase dual-capacitor motor has one starting capacitor and one running capacitor. The larger capacitance is the starting capacitor, and the smaller capacitance is the operating capacitor. After the motor starts, the centrifugal switch disconnects the starting capacitor from the circuit.

Hello dear ! The 220V single-phase dual-capacitor motor has one starting capacitor and one running capacitor. The larger capacitance is the starting capacitor, and the smaller capacitance is the operating capacitor.

I am a single-phase motor with only one capacitor, how large is the capacitance of this capacitor?

Summary. Hello, I will help you answer this question, usually the motor above 300W adopts dual capacitors, both starting capacitor + running capacitor. The single capacitor operation type of the motor below 300W has only one capacitor, and the motor acts as a starting capacitor when it starts, and acts as a running capacitor after the motor runs normally.

Therefore, this capacitor is the starting capacitor when the motor starts, and the capacitor when the motor is running.
