it is said when hybrid cars break(for example toyota prius ) the energy which is caused by the friction between the ground and the wheels of the car ,is converted to electrical energy in order to supply it.
i would be happy if someone could explain this process.(another thing :is there any site that explains about car components and……?)
It uses the electric motor operating backwards, to convert motion to electrical power.
In more detail, when you press the brakes lightly, the motor is connected to the front wheels in a mode where it operates as a generator. In that mode, it acts as a retardant on the wheels, ie, exhibits a braking effect. As you press harder on the brake petal, the couping between the wheels and motor, initially low, increases, until it is at maximum, and the motor is doing all it can to slow down the car, converting mechanical energy to electrical energy and charging the battery. If you continue to press harder, the mechanical brakes come on and further retard the car, converting the energy into heat.

The Prius uses a Permanent magnet AC synchronous motor. Using the principals discovered by Michale Faraday when a wire passes through a magnetic field it will produce a current as the current is converted into a voltage and this will will produce a force against the wire. This force is the braking effect caused by the motor when the voltage is greater than the voltage in the battery.

My husband and I am always intrigued in informative posts about electro magnetic generators and free energy. This really opens my mind. excellent post and I have added you as a bookmark. thank you
