The PTC (positive temperature coefficient) relay is directly connected in series with the secondary winding (start winding) and in parallel with the main winding of the motor. When AC 220V is applied to the two windings, a phase difference will be generated due to phase separation, thus forming an elliptical rotating magnetic field and generating a starting torque to drive the normal operation of the motor. After that, because the PTC relay is under a high resistance state, the starting circuit is nearly disconnected, and only the running winding drives the motor to run.

When the current flows through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator. When the vector magnetic field of the stator rotates an angle, the rotor also rotates at an angle with this magnetic field. Every input of an electric pulse leads the motor to rotate at an angle to advance one step. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency.

A compressor is a kind of driven fluid machinery that elevates low-pressure gas to high pressure. It is the heart of the refrigeration system. It inhales refrigerant gas with low temperature and low pressure from the suction pipe, compresses the piston driven by the motor, and then emits refrigerant gas with high temperature and high pressure to the exhaust pipe to provide power for the refrigeration cycle.

The refrigerator malfunction may be caused by the refrigeration system or the electrical system. When judging the compressor fault, you should first confirm whether the electrical system is working normally. You should check if the power plug is in contact with the power switch, if the fuse is open, if the power connection is normal, and the power voltage. You should also inspect where the thermostat is placed, whether the temperature sensor leaks, whether the temperature adjustment is appropriate, and if the induction action is working.

Refrigerators are very common in our daily life. Most people know how to use refrigerators, but they do not know the relevant knowledge. Sometimes the refrigerator is out of order, but users do not know how to solve it. Today's home appliances, refrigerators, and air conditioners all have compressors, which are their core components. Once the compressor fails, these appliances will strike! To test the quality of the compressor, you need to master some basic knowledge, such as the judgment of the quality of the hermetic compressor? Today, we will let you understand how to test the refrigerator compressor.

The Variable Frequency Drive (VFD) is a device widely used to convert the constant voltage of an autonomous AC power source into a variable voltage for controlling the torque and speed of the motor. They are ideal for motors that drive loads on mechanical equipment. A VFD offers higher efficiency than simple inline motors, as well as a degree of control not available with simple drive motors. These factors can save energy costs, improve production performance and extend motor life.
