Vertical and horizontal are common installation types for energy-saving motor products. From the appearance and structure of energy-saving motors, there will be significant differences in the base and end cover of the two types of energy-saving motors.
Horizontal motors are mainly installed and controlled by the base, and some energy-saving motors require auxiliary installation through end covers, such as the common B35 motor. The representative feature of horizontal motors is that during operation, the energy-saving motor shaft is parallel to the ground. Vertical motors mainly use end caps as installation components, sometimes requiring auxiliary installation through the base. During motor operation, the shaft is perpendicular to the ground.
In addition to differences in appearance characteristics, most vertical motors also have certain differences in internal structure compared to horizontal motors, mainly manifested in the bearing system of energy-saving motors. For small-sized energy-saving motors, as long as the installation conditions are met, the two installation methods of energy-saving motors can be interchanged because there is no essential difference between the bearing systems of the two; But for most energy-saving motors, the bearing system structures of the two installation methods are different.

For vertical motors with larger specifications, due to the heavy weight of the rotor, the axial bearing capacity of deep groove ball bearings cannot meet the safety requirements for vertical operation. Angular contact ball bearings or other bearing combinations are needed to meet these requirements. In small and medium-sized energy-saving motors, angular contact ball bearings are used as positioning bearings for energy-saving motors. The positioning bearing can be located at the shaft extension end of the motor or the non shaft extension end of the motor, or at the upper or lower end of the motor; But the basic idea of bearing installation is to use bearings to "hoist" or "hoist" the rotor of energy-saving motors to ensure the safety of axial fit between the stator and rotor during the operation of energy-saving motors.
In actual production, manufacturing, and application processes, energy-saving motors using angular contact ball bearings must be stored, tested, or used according to their actual usage status. The tilting, inversion, and horizontal state of energy-saving motors can cause serious problems in the bearing system of energy-saving motors.
