Technology Parameteres :

A. High degree of standardization, general

B. Y2 series motor has a unique shape structure of parallel vertical fin, both to increase the cooling area, changed the traditional motor aesthetic appearance.

C. adopted to reduce the noise, vibration measures, the noise of the motor, vibration are relatively low, respectively 5.55 dB (A) and lower than the Y series of about 0.5 ~ 0.9 mm/S.

D. has the high locked-rotor torque, maximum torque, the minimum torque power equal to the rated torque of Y series motor is 0.11 ~ 0.22 times higher.

E. has lower multiples locked-rotor electric current and the ra
