Adjusting 220V 1.1KW Single-Phase Motor Speed from 700 to 1400 RPM Smoothly

The discussion revolves around methods to smoothly adjust the speed of a 220V, 1.1KW single-phase induction motor from 700 to 1400 RPM. Participants clarify that the motor is a squirrel-cage induction type, which requires an inverter for speed control, as traditional methods like triac control or voltage adjustment are unsuitable. Suggestions include using a frequency inverter, specifically for single-phase motors, which can provide smooth speed regulation and maintain torque. Some participants mention the possibility of using gear motors or mechanical solutions for speed adjustment. The conversation also touches on the limitations of using triacs and the importance of selecting appropriate capacitors for efficiency. Brands like Invertek are recommended for inverters, with discussions on their compatibility with different motor types.
