Electromagnetic braking

Electric cars have several advantages over cars running on a combustion principle. The main ones are silence in operation, absence of vibration, diminished maintenance, and the availability of electromagnetic braking, the electricity from which can be used to produce extra H2 fuel from the water obtained when H2 is combined with airborne oxygen.

Exciting developments based on electromagnetic induction raced along from that time, giving us the sophisticated products our everyday lives depend on. During most of the period productive uses for eddy current technology were few and few people believed in it as a usefiil tool eddy currents caused power loss in electrical circuits and, due to the skin effect, currents flowed only in the outer surfaces of conductors when the user had paid for all the copper in the cable. The speedometer and the familiar household power meter are examples of everyday uses that we may tend to forget about. The brakes on some models of exercise bicycle are based on the same principle.

As we have aheady mentioned, a charged particle in motion with a decreasing speed emits an electromagnetic radiation called braking radiation. On the contrary, when a charged particle is accelerated, the electromagnetic radiation that is emitted is called synchrotron radiation [SCH 49]. 

Bremsstrahlung - Electromagnetic radiation generated when the velocity of a charged particle is reduced (literally, braking radiation ). An example is the x-ray continuum resulting from collisions of electrons with the target in an x-ray tube. 

The system selects the IRTP series sensor to monitor the temperature of the brake shoe. IRTP sensor series are economical temperature sensors. Monitoring accuracy is not affected by pollution, moisture and the influence of electromagnetic interference environment. 

Plugging involves a reversing contactor that, when operated, swaps two of the phases on the supply to the motor - the motor is then said to be plugged . This reverses the electromagnetic field that drives the motor and causes the motor to decelerate. If the plugging is not removed when the motor stops, the motor will then reverse its direction, which may be hazardous. Care must therefore be taken in the design of this type of braking system.
