Description

technical field [0001] The invention relates to the technical field of motors, in particular to a micro-power consumption electronic starter without PTC chips and contacts. Background technique [0002] With the improvement of people's living standards, the use of refrigerators has become very popular, and some families are also equipped with multiple refrigerators. The refrigerator compressor is a key component of the refrigerator. Refrigerator compressors are between frequent starts and runs for a long time. Because low-power refrigerators, especially refrigerator compressors for household refrigerators, mostly use single-phase AC motors. Single-phase AC motors rely on access to the secondary winding to start the motor. When the motor runs normally after starting, the auxiliary winding will no longer participate in the running work, and it will be turned on for a long time, which will not only consume electric energy, but also increase the calorific value of the motor a...
