Because the power source available on a public power grid is AC. The reason AC is used is because there is less loss due to long distance wires in AC because high voltage lines can be used and easily reduced locally by Transformers.
What else can I help you with?
Where can I buy the best ac motor?
The company Baldor is widely known as the best AC motors on the market. You can find these motors at the website www.baldor.com/products/ac_motors.asp.
Can you use AC in motor?
AC current is used in motors.
Why does modern hybrids use ac synchronous motor instead of dc series motors?
Toyota uses AC motors, Honda uses DC motors. It varies with design goals.
Do cars use DC motors to move wheels?
No they do not. The conventional car uses a petrol engine to move the motion wheels. Some hybrids use a combination of petrol engines and AC motors. While other use just AC motors.
Are the fan motors on fanuc ac spindle motors ac or dc?
usually ac 110v even on the dc motors
who is more efficient dc motor or ac motor and why?
DC motors are generally more efficient than AC motors. DC motors have a lower amount of inertial associated with them, making them more efficient to run.
Why dc series motors cannot be used in home?
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
What are the applications of an AC motor?
Most of the motors are AC. Fans, Mixer, Industrial equipment, Aircon, vacuum cleaner, plenty of applications use AC motor
What are some common uses for AC motors?
There are quite a few types of AC motors that are used in everyday common applications. The AC motor is generally used more so than a DC motor. Some of the more well known and practical uses for a AC motor include, water pump motors, robot arm motors and various other uses that make the life of the common man easier.
Who to increase torque of ac motors?
ac voltage
Why do we use capacitors on fan blower motors?
Some AC motors are designed to start running as soon as electricity is provided. Other AC motors are designed for a specific purpose and do not start on AC current. They will RUN on AC, but require a DC current to start. Here's where the capacitor comes in. It stores DC power that, when released, starts the motor turning. At this point, AC current will nicely run the motor.
Do step up and down transformer only work with ac power or can you use them in dc only?
AC only. That's one of many reasons why AC is more useful (and more widely used!) than DC.
