Is it possible to make a smooth start of a three-phase motor through a halogen lamp protection unit?
Two asynchronous three-phase motors - each 1500 rpm power 0.37 W 380 3 phases. Connected to the mechanism through gears. At the time of starting the engine loosens and breaks the key. It is impossible to change the mechanism. Need a smooth start. If the halogen lamp protection unit is placed in series for each phase, will the engine accelerate more smoothly? (TDM BZ-500 soft start of halogen lamps up to 500 watts acceleration 3 sec. 3 pcs = 800r). Chastotniki not offer, the budget does not allow!
Yes, a smooth increase in voltage will slow down the acceleration of the engine. Though with a loss of momentum. In short, you need to try here. 3 pieces do you want to install one per phase? But 500 watts will not be enough, they can not withstand the current at startup, of course, the starting currents will decrease, but how hard it is to judge. Personally, I have not encountered such an application of soft starters for lamps. But the idea is not bad.
