FAQ
During the operation of the asynchronous motor, various faults will appear. So how should we deal with this kind of fault phenomenon and how to eliminate it? Today I will give you a brief introduction, I hope it can be useful to you help.
1. The motor does not start
1. The power supply is not connected: check the switch, melting wire, each pair of contacts and motor terminals.
2. Winding open circuit: heat the open circuit part to the temperature allowed by the insulation class, soften the paint, then stir up the broken wire, repair the broken wire with the same specification wire, wrap the insulating layer, and then paint and dry.
3. Winding grounding or short-circuit between phases and turns: The treatment method is the same as above, only insulate the grounded or short-circuited parts, and then paint and dry.
4. Winding wiring error: check the wiring diagram, and connect the ends according to the correct connection (including binding, insulation treatment, painting) after heating the end.
5. Melt burned out: find out the cause, eliminate the fault, and prepare a new melt according to the specifications of the motor.
6. Wrong operation of winding rotor motor starting: check the position of the collector ring and the short-circuit device of the starting rheostat. When starting, connect the rheostat in series with zero, and then connect the short-circuit device after starting.
7. The set value of overcurrent*** is too small: increase appropriately.
8. The old start switch oil cup is short of oil: add new oil to the oil level line.
9. Control equipment wiring error: the wiring is correct.
2. The melted wire is burnt after the motor is connected to the power supply
1. Single-phase start: check the power cord, motor lead wire, fuse, switch contact, find out the broken wire or false connection fault and repair it.
2. The stator and rotor windings are grounded or short-circuited: correct the error.
3. The motor load is too large or stuck: adjust the load to the rated value and eliminate the failure of the drag mechanism.
4. The cross-sectional area of the melt is too small: the melt cannot protect the motor from overload. Generally, the melt is selected according to the following formula, the rated current of the melt = locked-rotor current/2 ~ 3.
5. The starting resistance of the wound rotor motor is too small or short-circuited: eliminate the short-circuit fault or increase the starting resistance.
6. The connection wire between the power supply and the motor is short-circuited: check the short-circuit point and repair it.
3. The motor does not start after being energized and buzzes.
Improper selection of slot matching after changing pole rewinding: select reasonable winding form and winding pitch; appropriate small rotor diameter; recalculate.
