1. Generally speaking, small asynchronous motors refer to induction running asynchronous motors. This type of motor uses auxiliary coils and capacitors not only during startup but also during operation. Although the starting torque is not very large, it has a simple structure, high reliability and high efficiency [7].
2. With the size of the load, the rated speed of the motor will also change.
3. It can run continuously.
4. It is used in applications that do not require speed braking.
5. Use the E insulation grade, while the UL type motor uses the A type.
6. There are two types of induction running single-phase asynchronous motors and three-phase asynchronous motors.
7. The single-phase motor is an induction running asynchronous motor with high efficiency and low noise.
8. When the single-phase asynchronous motor is running [2], the torque opposite to the rotation direction is generated, so it is impossible to change the direction in a short time. The direction of rotation should be reversed after the motor has come to a complete stop.
9. The power supply of single-phase motor includes A (110V 60Hz), B (22V 60Hz), C (100V 50/60Hz), D (200V 50/60Hz), E (115V 60Hz), X (200-240V50Hz), etc.
10. Use U (200V 50/60Hz), T (220V 50/60Hz), S (380-440V 50/60Hz) asynchronous motors for three-phase motors.
