What is the difference b/w synchronous and asynchronous motor?
two different electric machines both on AC power supply. While I don’t want to go deep into boring formulas, electricity and magnetism.. I can say their main uses: Asynchronous machines are used as motors mainly, and have a slight slip of the rpms (like our rotating field is rotating with 1500rpm, while our rotor unloaded is turning at 1490rpms – under load it can drop far as 1200rpms). Basically you can tell it’s an asynchronous motor if it has cooling fins (they’re running hot). They tend to be used almost everywhere, fans, grinders, many power tools, cable elevators, electric locomotives (only recent, it tends to replace the CCseries motors with asynchronous motors), and most of the motors ranging in almost any size and power Synchronous machines are mainly used as generators (that deliver electric power when turned). They are usually large, and very large (big as a house), used in power stations (they are turned by a gas turbine inside a thermocentral power plant, or steam turbines
