Product Description

1.Motor Introduction 
YB3 series explosion proof three-phase asynchronous motor is the basic explosion proof motor product that is developed by combining current market and domestic explosion proof motor industry. Basing on YB3 basic series motor, we may derive it into many kinds of explosion proof motors such as YB2-W outdoor type.YB3-WTH outdoor humid&tropic type etc.
