Speed regulators

SHUFT speed regulators are designed for speed control and air flow control of ventilators.

There are one-phase and three-phase speed regulators. On the mode of operation there can be step-type, thyristor and frequency regulators.

Operation of step-type regulators are based on the use of autotransformers. Step voltage control. Manual speed regulation. Operation of thyristor regulators are based on the smooth variation of out voltage. They are used for manual regulation of rotation speed of fan electric motors.

Operation of frequency regulators are based on the smooth change of voltage frequency of fan motor. These regulators are used for rotation speed control of cage induction motors.
