The speed of a synchronous or induction AC motor is dependent on the frequency of the AC power supply, so changing frequency allows the motor speed to be changed. This allows fan or pump output to be varied to match process conditions, which can provide energy savings.
Frequency Converters, also known as "Frequency Changers", transform electrical power as it relates to 25Hz, 50Hz, 60Hz, 100Hz, and 400Hz. This conversion is achieved through either a Static Frequency Converter (double conversion method) or a Rotary Frequency Converter (motor-generator set).
For example, an ac motor designed to operate at 60 Hz runs slower if the frequency drops below 60 Hz, faster if it exceeds 60 Hz. For ac motors, any change in frequency causes a proportional change in motor speed. Another example is a 5% reduction in frequency produces a 5% reduction in motor speed.
A fan is provided with a current of 400 VAC, 50 Hz. At this frequency (50 Hz), the fan can run at a certain speed. To get the fan to run faster, a frequency converter is used to increase the frequency to (for example) 70 Hz.
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light.
In telecommunications, frequency-change signaling is a telegraph signaling method in which one or more particular frequencies correspond to each desired signaling condition of a telegraph code.
frequency noun (HAPPENING) the number of times something happens within a particular period, or the fact of something happening often or a large number or times: frequency of Complaints about the frequency of buses rose in the last year. the increasing frequency of terrorist attacks.
