Summary
The lowercase letter following the traditional MY, MC and ML represent the generation of our products. MYd, MCd, and MLd series are Wonder's most advanced 4th generation single phase motors. Those motors have the product features of low noise, low vibration, high efficiency, wide voltage range, novel appearance, IP55 protection, class F insulation, and mounting dimensions in accordance with IEC standard.
Main Application
MLd is with dual capacitors, while MYd is capacitor run and MCd is capacitor start. All new single phase motors are with electronic starting switch. MLd and MCd series are suitable for high starting torque application like air compressors, while MYd series is mainly for low starting torque application such as fan and pumps.
