Vertical type and horizontal type are relatively common installation types of motor products. From the appearance and structure of the motor, the base and end cover of the two types of motors will have obvious differences.

Horizontal motors are mainly installed and controlled by the machine base, and some motors are also assisted by end covers, such as the more common B35 motors. The most representative feature of horizontal motors is that during the operation of the motor, the motor shaft parallel to the ground. The vertical motor mainly uses the end cover as the installation part, and sometimes needs to be assisted by the base for installation. During the operation of the motor, the shaft is perpendicular to the ground.

In addition to the difference in appearance characteristics, the internal structure of most vertical motors and horizontal motors has certain differences, mainly in the bearing system of the motor. For small-sized motors, the motors of the two installation methods can be interchanged as long as the installation conditions are met, because there is no essential difference between the bearing systems of the two; but for most motors, the bearing system structures of the two installation methods are different. of.

For vertical motors with larger specifications, because the weight of the rotor is heavy, the axial load capacity of the deep groove ball bearings cannot meet the safety of its vertical operation, so angular contact ball bearings or other bearing combinations are required to meet the requirements. . In small and medium-sized motors, angular contact ball bearings are used as the positioning bearing of the motor. The positioning bearing may be at the shaft extension end of the motor or at the non-shaft extension end of the motor, that is, it may be at the upper end of the motor or at the lower end of the motor. Part; but the basic idea of bearing installation is to "suspend" or "lift" the rotor of the motor through the bearing to ensure the safety of the axial cooperation between the stator and the rotor during the operation of the motor.

In the actual manufacturing and application process, whether it is stored, tested or used, the motor using angular contact ball bearings must be carried out according to the actual use state. The tilted, inverted, and horizontal state of the motor will cause the motor bearing There is a serious problem with the system .
