Описание

The motor (or output) choke is designed to improve the quality of the motor power supply and is installed at the output of the frequency converter. The motor choke increases the inductance in the output circuit and reduces current fluctuations and voltage rise rate, thereby increasing the service life of the motor windings. The use of the output choke is advisable with a sufficiently long power circuit from the frequency converter to the engine. Usually it's recommended to put in the circuit length of more than 20m. At large distances of 50 meters or more from the frequency converter to the engine, the use of the choke is mandatory. ONI chokes differ in the stability of the respective characteristics due to the use in the production of high-quality materials, strict compliance with the intricacies of the manufacturing process in the production and stringent final inspection of finished products.
