What are some common sensor failures and their solutions in motor motor rotor slot wedge machines?

The following are some common sensor failures and their solutions in motor motor rotor slot wedge machine:

1、the sensor does not work:

Fault phenomenon: the sensor has no output signal.

Solution: Make sure the power supply of the sensor is normal, and check whether the power connection, interface and voltage meet the specifications.

2、the signal is not stable or no signal:

Failure phenomenon: the sensor output signal is not stable or no signal.

Solution: Use an oscilloscope or multimeter to measure the output signal of the sensor, check whether there is a pulse signal output. If there is no signal, the sensor may be damaged or poorly connected, need to check or replace the sensor.

3、signal loss or interference:

Fault phenomenon: sensor signal loss or interference.

Solution: Check whether the connecting wire from the sensor to the controller is firm, broken or short-circuited. Replace the connection line if necessary.

4、Signal instability or inaccuracy:

Fault phenomenon: the sensor signal is unstable or inaccurate.

Solution: Confirm whether the installation position of the sensor is correct, and whether the distance between the rotor or magnet is within the specified range, to avoid contact with the rotor shaft.

5、signal waveform distortion:

Fault phenomenon: sensor output signal waveform distortion.

Solution: Check whether there is electromagnetic interference (EMI), to ensure that the sensor and the signal line away from high-voltage cables and other possible sources of interference.

6、speed inaccuracy:

Fault phenomenon: motor speed sensor measured speed is not accurate.

Solution: Confirm whether there is a mark on the rotor or the magnet is working properly, make sure there is no wear or fall off.

7、Hall sensor failure:

Fault phenomenon: Brushless DC motor Hall sensor failure may lead to inaccurate detection of motor rotor position.

Solution: Based on the speed observer fault diagnosis method, detect and compensate the fault of Hall sensor by analyzing the Hall signal and its jump along the signal.

The above are some common sensor failures and their solutions in motor motor rotor slot wedge machines, specific problems may require detailed diagnosis and professional maintenance according to the actual situation.
