How a synchronous motor works is described in detail, including the magnetic impulses which drive the motor. A synchronous motor is not inherently self starting. In a non self starting clock there is a manually operated device which runs the motor up to the synchronous speed in the correct ...

In synchronous AC motors, the rotor turns at exactly the same speed as the rotating magnetic field; in an induction motor, the rotor always turns at a lower speed than the field, making it an example of what's called an asynchronous AC motor. The theoretical speed of the rotor in an in...
Once upon a time you'd have found gadgets like this only in space rockets or jumbo jets; now they're in virtually every car, many laptop computers, and all kinds of gadgets such as smartphones and games consoles. Let's take a closer look at what they are, what they do, and how ...
How It Works Traditional vehicles “coast” when you remove your foot from the accelerator pedal. One-Pedal Driving uses the electric motor to capture energy from the vehicle’s motion to recharge the battery and quickly slow down the car. When you need to stop suddenly in an emergency, you...
Three-phase motors are motors designed to run on the three-phase alternating current (AC) power used in many industrial applications. AC electricity changes direction from negative to positive and back many times a second. The AC you get in your house, f
How a Stepper Motor Works How ESC Works (Electronic Speed Controller) An ESC or an Electronic Speed Controller controls the brushless motor movement or speed by activating the appropriate MOSFETs to create the rotating magnetic field so that the motor rotates. The higher the frequency or the quick...
How a Liquidity Cushion Works A liquidity cushion protects an individual or a business from having to sell illiquid assets likereal estateor equipment to pay off debts. The same principle applies to banks and other financial institutions that buy and sell assets by borrowing money, also known as...
It must be powered primarily by an electric motor that draws its charge from rechargeable batteries or fuel cells. Vehicle owners may qualify for the full $7,500 credit, as long as they fill out Form 8936. The credit phases out after a certain period of time, which is based on the manu...
