ML Series Single-Phase Induction Motor Description
Single-phase motors generally refer to low-power single-phase asynchronous motors powered by a single-phase AC power supply (AC220V). Such motors usually have two-phase windings on the stator, and the rotor is a common squirrel-cage type. The distribution of the two-phase windings on the stator and the different power supply conditions can produce different starting characteristics and operating characteristics.
A Single-phase motor refers to an asynchronous motor that is powered by a 220V AC single-phase power supply. Because the 220V power supply is very convenient and economical, and the household electricity is 220V, single-phase motors are not only used in large quantities in production. Still, they are also closely related to people's daily lives, especially as living standards continue to improve. Therefore, the use of single-phase motors for household appliances is also increasing.
ML Series Single-Phase Induction Motor Application
In production, there are micro water pumps, refiners, threshers, shredders, woodworking machinery, medical equipment, etc. In life, there are rice machinery, cutting machine, exhaust fans, washing machines, refrigerators, etc. There are many types. But less power.

Note for motor operation:
① Observe from the ammeter whether the motor current exceeds the rated current marked on the nameplate.
② Voltage of the motor. Too low voltage or unbalanced three-phase voltage will overheat the motor.
③ The temperature rise of the motor. After the motor runs, the temperature will gradually increase, but it cannot exceed the allowable temperature rise and generally cannot exceed 60 ° C. Add 15 ° C to the test temperature according to the thermometer to allow the temperature to rise.
④ Bearing temperature. The temperature of sliding bearings should generally not exceed 70 ° C; the temperature of rolling bearings should not exceed 80 ° C.
⑤ Whether the motor is vibrating, whether the unit's sound is abnormal, whether there is an abnormal smell or smoke, etc.
