Classified according to the size of the motor structure

(1) Large motor refers to the center height of the motor base greater than 630mm, or the No. 16 base and above. Or the outer diameter of the stator core is greater than 990mm. It is called a large electric motor.
(2) Medium-sized motor refers to the center height of the motor base between 355 and 630mm. Or base 11-15. or the outer diameter of the stator core is between 560~990mm. It is called a medium-sized motor.
(3) Small motor refers to the center height of the motor base of 80-315mm. or No. 10 and below the base, or the outer diameter of the stator core is between 125-560mm.
