YDK-70A/50A Motor
Single-phase capacitor motor, up to 120 W and 1,000 RPM, with stable, low-vibration, low-noise running.
Optional Parameters
Capacitor-Compensated, Smooth Running
The YDK-70A/50A are single-phase capacitor motors. The stator carries working and starting windings (capacitor-start) or running windings (capacitor-run) fixed on the core, while the squirrel-cage rotor of bars and end rings spins in the stator field without separate excitation. Rated up to 120 W at speeds up to 1,000 RPM, they run stably with relatively low noise and vibration, and capacitor compensation improves power factor while cutting reactive power — serving household fans, washing machines, range hoods, small machinery and irrigation equipment.
Core Advantages
- Up to 120 W: Rated up to 120 W at speeds up to 1,000 RPM
- Squirrel-Cage Rotor: Bar-and-end-ring design spins without excitation current
- Capacitor Compensation: Higher power factor with less reactive power
- Smooth and Quiet: Stable running with relatively low noise and vibration
