Darect on line statar
This method for starting motors is traditionally used in devices such as compressors, fans, water pumps, and conveyor belts.
A direct on line starter can be used in conjunction with a second DOL circuit, providing the motor with the ability to run in both forward and backward directions.
As the name suggests, direct-on-line starting means that the motor is started by connecting it directly to the supply at rated voltage.
Direct-on-line starting, (DOL), is suitable for stable supplies and mechanically stiff and well-dimensioned shaft systems – and pumps qualify as examples of such systems.
Go back to Methods ↑ Small motors which do not start and stop frequently need only very simple starting equipment, often in the form of a hand-operated motor protection circuit breaker.
This is so broad, however, that it may not make a direct and vivid impression.
