Scenario-based Application of Speed Control Technology

Frequency conversion speed regulation

   Applicable scenario: equipment requiring precise speed control (e.g. centrifugal pumps, fans), significant energy saving effect.

   Advantages: wide speed range (5%-100%), high efficiency, support soft start to reduce mechanical impact.

Variable pole speed control

   Applicable scenarios: the demand for speed regulation (such as double-speed machine tools, elevators), low cost and simple maintenance.

   Typical solution: 4/6 poles two-speed motors, realize high and low speed conversion by switching windings.

Mechanical speed control (fluid coupling/gearbox)

   Applicable scenarios: high-power equipment (e.g. ball mills, mining crushers) to avoid direct motor overloading
