what type of motors do we have in juicers, blenders, grinders vacuum cleaners ?I think they are all contains dc motors but what kind of dc motors they have ?
i think theyre actually ac because ive never seen a converter on one
I know my Philips vacuum cleaner has a 'universal motor'. A universal motor can be operated by both ac or dc but the voltage is different. You can connect a dc to the plug pins to make it spin. But not if it is equipped with variable speed. In many cases, 12V dc is just enough to make it spin but higher voltage makes it spin faster (I have ever made it run in this way). A universal motor is very commonly used on power hand drills or other power tools. Its advantages are light-weight and high torque at low speed. This motor also has its negative sides: it is noisy and has (carbon) brushes. maintenance is therefore needed and its has spark when running. This motor is also called series motor because all of the windings are connected in series. In the contrary, squirrel cage induction motor is more common for other applications, such as fans, water pumps. Its advantages are quiet and maintenance is minimal.
