The motor manufacturer invented that the motor is an important power provider that people cannot lack in production and life.In recent years, under the greet of the country, high-efficiency and energy-saving motors and variable-frequency speed-regulating motors have gradually replaced ordinary motors.

　　However, in some environments, there will be severe fever during the process of using high-power motors, and the manufacturers often do not know how to handle it.

　　Below, Hubei Wanbang motor manufacturer will sort out and clarify the common reasons that cause high-power motors to heat up.

　　XNUMX. There are short-circuit windings, short-circuits between turns, short-circuits between phases, and open windings in high-power motors.

　　After the insulation between two adjacent wires in the winding of a high-power motor is damaged, the two conductors collide, which is called a winding short circuit.Winding short circuits generated in the same winding are called inter-turn short circuits.The winding short circuit generated between the two phase windings is called interphase short circuit.Regardless of that, the city increases the current of one or two phases, causing local fever, and aging the insulation and damaging the motor.Winding open circuit refers to the obstacle caused by the broken or blown stator or rotor winding of the motor.Regardless of whether the winding is short-circuited or open, it may cause the motor to fever or even burn.Therefore, it is necessary to shut down and deal with punishment immediately after this environment is created.

　　XNUMX. The material leaks into the inside of the high-power motor, so that the motor insulation is low, so that the motor allows the temperature rise to be low

　　When solid materials or dust enter the motor from the junction box, they will reach the air gap between the stator and rotor of the motor, causing the motor to sweep the cavity, until the motor winding insulation is worn out, and the motor is damaged or scrapped.If the liquid and solid medium leak into the motor, it will directly cause the insulation of the motor to drop and cause a serious trip with fever.
