Vacuum cleaners with soft starter
Soft start of motor
— a limiter reduces the starting power of the vacuum cleaner motor and provides a smooth start.In the absence of such a limiter, the starting power (power at the moment the engine starts) turns out to be very high - often many times higher than the nominal value. It creates a high load on the power supply, and if the power is supplied from the mains, it leads to voltage surges in it. And the electric motor itself also experiences increased mechanical loads since it spins up very quickly, with a jerk. The reduction of the starting power using a soft start system avoids these phenomena. On the other hand, additional electronic circuits affect the cost of the vacuum cleaner, sometimes quite significantly. So there are few models with this feature nowadays. And you should pay attention to them mainly in cases where the mentioned advantages are of fundamental importance - for example, if a vacuum cleaner is purchased for a house with weak wiring that does not tolerate voltage surges.
