Three-phase chokes are used to safeguard a motor against harmonics, so detrimental to a motor. Motor chokes are commonly used in AC converting power transmission systems. These chokers successfully dampen both high frequency and low frequency circuit distortions.They ensure motor current continuity and smooth its pulsation, reduce short-circuit current in converter load system, as well as dampen commutation overvoltages and compensate the supply line capacitance.
They smooth motor current pulsation, dampen commutation overvoltages, compensate supply lines capacitance and improve current sinuosity and motor voltage. They are inserted between a motor and a converting system. Chokers lengthen a motor failure-free operation time and reduce generated noise.
