The common Y series three phase asynchronous motor mainly have three kinds of machine, which are B3, B5, B35. This is the most common installation way of common three-phase asynchronous motor.
1.B3 has a base, no direct connection flange plate
2.B5 has no base, and there is a direct connecting flange.
3.B35 has a base, and there is a direct connecting flange.
There are many ways of installing motor, which are mainly horizontal and vertical. In the horizontal and divided into B3, B35, B34, B5, B6, B7, B8, B9, B10, B14, B15, B20, B30; V1, V15, vertical is divided into V2, V3, V36, V4, V5, V6, V8, V9, V10, V14, V16, V18, V19 V21, V30, V31; but the most commonly used real production is B3 (generally horizontal type) and B5 (with no foot flange) B35 (with foot flange mounting).
B3 and B35 are horizontal installation, the main difference is B3 (horizontal), B35 (with foot flange)
B5 (flanged no foot) refers to the vertical flange mounting type motor, it is often said that the installation.
V1 and V3 are B5 installation under segmentation: V1 axis V3 axis stretch, stretch, B5, V1 and V3 belong to the FF installation flange installation, only B5 is horizontal flange (axis is horizontal), V1 is a vertical flange (head down), and V3 is the head of the flange install. In general, V1 and V3 may have problems with axial endurance. But a better motor manufacturer can be replaced when it is designed.
