Working Principle of Simo Motor's SYQ6 Series Liquid Resistance Starting Cabinet
A specially formulated electrolyte is connected in series as a resistance within the rotor circuit of the controlled wound motor. By adjusting the concentration of the electrolyte and altering the distance between the two polar plates, the value of the series resistance constantly meets the requirements of the motor's mechanical characteristics for the series resistance value during the starting process. As a result, the motor can increase its speed evenly and start smoothly while achieving the maximum starting torque and the minimum starting current. Once the starting process is completed, the electrical switch shorts the rotor circuit.
Main Performance Characteristics of Simo Motor's SYQ6 Series Liquid Resistance Starting Cabinet
Soft start with a small starting current: Iq ≤ 1.3Ie (A).
It reduces the temperature rise of the motor during the starting process, effectively extending the service life of the motor.
The starting process is smooth, imposing no impact on mechanical equipment.
It can be started continuously for 5 to 10 times, and its starting performance is superior to that of the frequency-sensitive starting cabinet.
It has low requirements for the power grid and will not generate harmonics that affect the power grid.
It features a reliable and simple structure, facilitating installation and maintenance.
It has good versatility and can be applied to the soft start of wound motors under any load conditions, especially suitable for heavy-duty starting.
It is equipped with multiple protection functions such as starting timeout, loss of voltage, over-travel, and over-temperature.
When used in cold regions in the north, the equipment comes with an electric heating function.
