Structural features
The motor adopts box-type structure,which is light in weight,good in rigidity,and convenient for installation,maintenance and repair of the motor.Y,YR series motors are the basic series,the protection level is 1P23 or P44(duct ventilation).After removing the protective cover or cover,and installing different top covers or covers on the top or side of the machine base,the YSK can be formed.,YRSK series motors,and other derivative series can also be derived.
The stator of the motor is an external press-fitting structure,and the vacuum pressure dipping or integral dipping process is adopted to make the windings have good insulation performance and moisture-proof performance.The rotor shaft adopts welded rib structure,the Y series rotor windings are made of copper bars,and the YR series rotor coils are made of F grade insulating materials wrapped around copper bars.
The bearing adopts a sliding bearing structure and is designed for oil lubrication according to P54.The protection grade of the main outlet box is IP54,and its inlet hole is generally at the bottom.
