Hubei Motor Manufacturer-Wanbang Motor Factory reminds that the lack of phase operation of three-phase asynchronous motors refers to the lack of one phase of the three-phase power supply or the disconnection of one of the three-phase windings of the motor from the power supply. Open-phase operation or single-phase operation.

　　The following are the reasons for the lack of phase operation of the motor organized by the motor manufacturer.

　　Generally speaking, the lack of phase operation of a three-phase asynchronous motor refers to a kind of electrical hindrance to a single-phase operation when the three-phase asynchronous motor interrupts a live wire or breaks a phase winding during the operation process.The reasons for the lack of phase operation of the motor are generally:

　　The fuse of a certain phase is almost crushed due to poor melt battle or over-tightening of the fuse;

　　The melt current is selected too small, so that the current passing through is slightly larger, it will fuse, especially under the attack of the motor starting current, it is more likely to produce non-impeding fuse of the melt;

　　Improper installation, such as small loop kinks during single-core wire unwinding or damage to the motor load circuit caused by disconnection;

　　The permanent operation of the motor makes the internal discussion of the winding or the lead loose, or the partial overheating burns the winding, which makes the motor run in a phase loss.
