Difference between ac motor and dc motor
What's the difference between ac motor and dc motor?
Direct current (DC) electric motors work for the situations where speed needs to be controlled.
Direct current (DC) motors have a stable and continuous current. DC motors were the first and earliest motors used in the industry. They were found, however, to not be as good at producing power over long lengths. Electric companies found using DC motors to generate electric did not work because the power was lost as the electric was transmitted. Brush DC motors use rings that conduct the current and form the magnetic drive that powers the rotor. Brushless DC motors use a switch to produce the magnetic drive that powers the rotor. Direct current (dc) motors are often found in appliances around the home.
And alternating current (AC) electric motors are used differently based on what type of AC motor it is.
Single phase alternating current (AC) motors are known as general purpose motors. They work well in many different situations. These AC motors work great for systems that are hard to start because they need a lot of power up front.
Three phase (also called polyphase) AC motors are usually found in industrial settings. These motors also have high starting power built transmit lower levels of overall power. AC power gets its name from the fact that it alternates in power. The amount of power given off by an AC motor is determined by the amount of power needed to operate the system.
