How can direct current drive AC motors?
AC motor: a machine used to convert mechanical energy and alternating current energy. AC motor has become the most common motor because of the great development of AC power system. Compared to the AC motor and DC motor, because there is no commutator (see DC motor commutation), therefore has the advantages of simple structure, convenient manufacture, relatively strong, easy to make high speed motor, high voltage, high current, large capacity. The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts. In the early 1980s, the largest turbo generator reached 1 million 500 thousand kilowatts. The AC motor was invented by Nicola Tesla, an American scientist from Serbia.
Originally 24V battery driven 120W motor, want to use alternating current drive, need a AC/DC power.Buy a AC220V/DC24V 10A (big, expensive, how many, but safe) switching power supply.If you do it yourself, buy a 220V/12V 150-200W transformer, a 10A rectifier bridge, a heat sink, and a few 50V4700uF filter capacitors. Transformer voltage transformer to 12V, rectifier, filter, DC 24V.
