As the name suggests, DC motors use direct current as their power source. The AC motor uses alternating current as its power source.
In terms of price, DC motors with the same power are higher than AC motors, including the speed control device that controls the speed. The DC speed control device is also more expensive than the AC speed control device. Of course, the structure and maintenance are also very different.
In terms of performance, DC motors have stable speed and precise speed control, which cannot be achieved by AC motors. Therefore, under the strict requirements of speed, DC motors have to be used instead of AC motors.
AC motor speed regulation is relatively complex, but it is widely used because chemical plants use AC power.
