Single-phase Dual-capacitor Asynchronous Motor for Continuous Use in Residential & Industrial Environments

The YL100S-4 is a 0.75kW medium-speed general-purpose dual-capacitor asynchronous motor designed specifically for single-phase 220V scenarios. It features a cast iron housing and a semi-transparent structure, combining durability and visibility. Its classic dual-capacitor + centrifugal switch structure provides high starting torque and smooth operation, allowing direct load starting. Suitable for long-term continuous operation in civilian and industrial settings without three-phase power.

 

Model Number Interpretation:

- YL: Series code, representing a single-phase dual-capacitor asynchronous motor.

- 100: Frame center height (height from shaft center to mounting base, in mm), determining the foundation installation dimensions.

- S: Frame length code (short frame, suitable for 0.75kW power).

- 4: Number of poles; a 4-pole motor has a rated speed of approximately 1400r/min under a 50Hz power supply, classifying it as a medium-speed general-purpose type.
