The difference between AC motors and DC motors
Apr 28,2023 | Guangri
The main difference between AC motors and DC motors is the power they use and the way they work.
AC motors use an AC power source, and their voltage and current change over time, so their speed and output power also change over time. AC motors usually use induction motors or synchronous motors.
DC motors use a DC power supply, and their voltage and current remain constant, so their speed and output power also remain constant. DC motors usually use DC motors or brushless DC motors.
In addition, AC motors and DC motors start differently. AC motors usually require a starter to start, while DC motors can be started by changing the polarity of the power supply.
To sum up, AC motors and DC motors have their own advantages and disadvantages. Choosing the appropriate motor type in different applications can improve the efficiency and performance of the equipment.
