Water air conditioner motorWhat are the reasons for the failure? The editor of Ever Power has organized some for you.

Reasons for the burning of the motor

When the high-pressure fan motor of the water air conditioner motor lacks phase, the motor usually cannot start. Even if it can start under no load, there will be a buzzing sound as the speed increases, the motor will smoke and heat, and then it will have a burning smell.When the motor end cover is removed, you can clearly see that the winding end has 1/3 or 2/3 of the polar phase winding zoom or dark brown.

The reasons for this fault are roughly as follows: the fuse circuit of the motor power supply circuit is in poor contact or mechanical damage causes the fuse to blow; the specifications of the three-phase fuse of the motor power supply circuit are different, so the fuse with a small capacity is easy to blow. Choose the appropriate fuse according to the size of the motor power; the disconnector, rubber cover switch and other switches in the motor power supply circuit and the contact of the contactor may be burned or loose, and other problems can easily lead to the lack of phase of the high-voltage fan motor, so it should be Repair and adjust the dynamic and static contacts in time to ensure good contact; if the line is broken, there will be phase loss. Find the broken line and connect it firmly; the virtual welding between the motor windings leads to poor contact and phase loss. The connecting wires of the motor windings should be carefully checked and welded firmly.

Analyze the cause of the vibration of the water air-conditioning motor and the troubleshooting method

(1) The reasons for the failure are as follows:

①The hall connector of the motor is bad;

② Poor contact of the handlebar;

③There is interference in the speed signal line.

(2) Troubleshooting: Bad Hall connector of fan motor, reconnect.

②Poor contact of the handlebar, reconnect it.

③There is interference in the speed signal line, try to change the controller and instrument.

④The water air conditioner produces jitter during use, which is generally caused by poor contact between the Hall switch connector of the motor and the handlebar connector.Therefore, focus on checking the connectors, especially the motor Hall switch connectors.
