The most common type of motor used in daily life is a small induction motor (which is what we call a motor). Usually has the following characteristics:
A: household type is usually single-phase power supply. There are several types of parameters: A (110V 60Hz), B (22V), C (100V 50/60Hz), D (200V 50/60Hz), E (115V 60Hz), X (200-240V50Hz), etc..
Two: the need to change the speed of the reducer or regulator is usually used as an auxiliary. Of course, you can also use the speed reducer.
Three: continuous operation.
Four: the size of the load, the motor rated speed will change.
Five: AC motors are required to operate the three-phase power supply, but only a single phase power supply in residential areas or small commercial areas, so this type of motor will not work properly. Therefore, a single-phase induction motor.
Six: the single-phase induction motor has no endogenous starting torque, so it is necessary to use the auxiliary winding to produce the different phase of the winding current or the use of the shaded pole coil.
Seven: the starting torque of single phase induction motor is related to the phase difference between the main winding and the auxiliary winding current. The difference between the two phases is 90 degrees.
Eight: single phase induction motor starting torque comparison: capacitor start motor > permanent split capacitor motor > phase motor > shaded pole motor。
