Import Dyq3 Series Liquid Resistor Starters — Buy in Bulk from Supplier in China

The DYQ3 series liquid resistor starter is a motor starting device designed for large and medium slip ring asynchronous motors and low-voltage squirrel-cage motors. It replaces outdated rheostat systems by using a controlled liquid resistance in the rotor circuit to limit inrush current to less than 1.3 times the rated current, enabling smooth, stepless acceleration without mechanical shock. The system operates automatically over a preset time of 20 to 50 seconds, with adjustable timing to match load profiles. It is rated for motor powers from 50kW to 6000kW and rotor voltages between 200V and 2200V.

The liquid resistor is composed of a sodium bicarbonate-based electrolyte solution contained in a sealed tank with movable electrode plates driven by a servomotor. The resistance decreases gradually as the plates move closer, reducing impedance during startup. The system operates safely within a temperature range of 0°C to 60°C and can function at altitudes up to 4000m with ambient temperatures from -35°C to 50°C. The surrounding environment must be free of explosive gases, corrosive dust, and excessive vibration. The unit requires a three-phase 380V to 10000V power supply at 50Hz.

This equipment is commonly used in heavy industrial applications such as ball mills, hoists, compressors, blowers, and water pumps where high-inertia loads demand controlled startup. Buyers typically include mining operations, cement plants, and municipal water treatment facilities. The starter supports up to 3 to 5 consecutive starts without cooldown, and its automation includes display, communication, and fault protection. Packaging is standard industrial crate with internal foam cushioning. Lead time and MOQ are confirmed directly with the supplier, as they vary by custom configuration and motor rating.

Hubei Create Electric Co., Ltd. is a manufacturer based in Xiangzhou District, Hubei, China, specializing in industrial motor starting systems. The company is listed as an imported supplier with harbor-tier trust verification, indicating verified export compliance and logistics capability. There is no public data on years in operation, employee count, or annual revenue. The supplier does not claim certifications such as ISO or CE, nor does it list any client names or case studies.

The listing confirms the company produces custom liquid resistor starters to match motor specifications provided by buyers. They offer technical support for installation and debugging but do not state whether they provide on-site service or overseas warranty. The response rate and average response time are listed as zero, suggesting no active sales or inquiry handling on the platform. Buyers should verify technical compatibility directly with the supplier before placing orders.
