YL series two-capacitor single-phase asynchronous motors derive from Y series three-phase asynchronous motor, whose frame number installation dimensions and power rank are identical with Y series three-phase asynchronous motor. YL series motors are characterized by higher efficiency, energy-saving, higher starting torque, low nose, little vibration, safe and reliable operation. YL series motors can be extensively applied to freezers, pumps, blowers, small size machines, side-production agricultural industry and family electric devices, etc.
