Description

Technical Field

[0001] The present invention relates to the field of AC motor control, and in particular to a starting capacitor controller including a running capacitor. Background Art

[0002] The existing capacitor controllers on the market basically have a separate electronic centrifugal starting switch and a separate running capacitor. Generally, the starting capacitor is connected in series to the starting winding of the single-phase motor and in parallel with the working winding. The single-phase motor equipped with a centrifugal switch, that is, a dual-capacitor motor, is generally started under heavy load and requires a large starting torque. A starting capacitor is connected in series to the centrifugal switch. When the speed reaches a certain number of revolutions, the sleeve centrifuge uses centrifugal force to push open the centrifugal switch and cut off the starting capacitor. After completing the starting task, there is still a running capacitor left to continue working. This product consumes manpower, working hours, and space when used, and has a high probability of failure. Therefore, the existing technology needs to be improved. Summary of the invention
