Definitions
- the PTC summit is formed in a donut shape, and the opening is formed in the shaft of the small DC motor or the extension shaft thereof.
- the PTC thermistor provided on the conventional control board improves the response performance, and the current built-in the conventional plate thermistor makes the current larger. Two improvements have been achieved in reducing power loss after limiting.
