Liquid starters<\/h1>\n

How do liquid starters work?<\/p>\n

To start a three-phase asynchronous motor from standstill, the torque generated by the current must be higher than the moment of inertia of the application. The required starting torque<\/strong> always depends on the application. It is influenced by factors such as mass, inertia and friction values, and materials<\/strong> within the application.<\/p>\n

Starting resistors protect electrical components<\/h3>\n

Without a starting resistor, the starting current responsible for the movement would reach more than 7x the normal rated current. High starting currents lead to serious repercussions on the supply network.<\/p>\n

In addition, the starting resistance enables a soft start, which protects both electrical and mechanical components. Liquid starters limit the starting current and are preferably used where a very high starting torque is required. The robust design guarantees high operational reliability<\/strong> and long service life<\/strong> in the most difficult environments.<\/p>\n

Liquid starter soda solution<\/h3>\n

In the liquid starter, a soda solution of Na2CO3 is used as the resistance medium<\/strong>. The resistance value depends on the soda concentration. By changing the distance between a pair of electrodes per phase, the resistance can be varied continuously. In addition, the solution acts as a heat sink for the accruing start-up energy. The heat is then released to the atmosphere via the tank surface.<\/p>\n

For higher tempering frequencies, heat exchangers can also be used as an option.<\/p>\n

GINO AG has taken over the French manufacturer for liquid starters \"AKA Automatismes\" in 2020. We now offer the established AKEP<\/strong> (standard series) and MAK<\/strong> (special for mining) starters through our newly founded subsidiary GINO-AKA<\/a>.<\/p>\n
