What is the relationship between power and stator and rotor size? Is there a clear relationship between stator length and rotor length, and outer diameter and output? In fact, the motor also has a certain size. The standard size differs depending on the motor type. Motors can be divided into large motors, small motors and medium-sized motors according to their related parameters. The size of the motor mainly affects the working space of the engine.
The higher the output power of the motor of the same model, the larger the size of the stator and rotor. The higher the power, the larger the number of windings and the larger the stator. Since the gap between the rotor and the stator is fixed, the rotor is also very large.
In industrial production, the model size of the motor is fixed (there are corresponding domestic standards, etc.). Under the same standard, the size of the stator and the rotor can be considered to correspond to the size of the power.
The motors are divided into four types: large, medium, small, and micro according to the difference of the center height, of which the center is the highest. For example: H belongs to 45 mm~71 mm micro motors, H belongs to 80 mm~315 mm small motors, H belongs to 355 mm~630 mm medium-sized motors, and H belongs to large motors above 630 mm.
GB/T1497-1988 General three-phase motor structure and size classification
1. Large motors
Large motors above No. 16, or the center height of the valve seat is greater than 630 mm, or the outer diameter of the stator core is greater than 990 mm, are called large motors, such as outdoor fan motor, gm blower motor.
2. Medium-sized motor
If the center height of the 11-15 medium-sized motor is 355×630 mm, or the outer diameter of the stator core is between 560-990 mm, it is called a medium-sized motor, such as a convection oven motor and aircon fan motor.
3. Small motor
If the center height of the small motor is 80×315 mm, or the outer diameter of the stator core is between 125~560 mm, if the number of seats is 10 or less, or the center height of the valve seat is 80×315 mm, or If the outer diameter of the stator core is between 315 mm, it is called a small motor.
The standard size of the motor output shaft is related to the seat number. Y80 frame size is 19 mm, Y90 frame size is 24 mm, Y 100 and Y 112 are 28 mm, Y 132 is 38 mm, Y 160 is 42 mm, Y 180 is 48 mm, Y 200 is 55 mm, and Y 225 -2 pole is 60 mm, Y 250 is 60 mm, Y 250 is 65 mm, Y 280-2 is 75 mm, Y 315-2 is 75 mm, Y 225-2 is 60 mm, Y 250 is 65 mm, Y 280 -2 is 75 mm, Y 225-2 is 60 mm, Y 280-2 is 65 mm, and Y 280-2 is 75 mm.
