Why use a frequency inverter along with an electric motor?
An electric motor and an electricity generator are basically the same. By principle, any electric motor can also generate electricity. Electric drives are way ahead of combustion engines, since, unfortunately, a car engine which sucks up exhaust fumes during braking and downhill rides and converts them into fuel and fresh air is still pending. The electric motor can deliver this, although during its first century of existence, its use has largely been hampered by two basic drawbacks: • An electric motor has no accelerator pedal. • A socket has no sort of “water tap”. When an electric motor is running, it generates a voltage with a polarity opposite to the feeding voltage. Therefore the current is excessively high at the first instance of switching on when the motor is not yet running. For big motors precautions have to be taken not to damage it or blow any fuses. As the motor speeds up, this induced voltage increases. In fact when exceeding the speed where the applied voltage and the m
