What are the common sensor failures and their solutions for motor motor rotor automatic rewinders?

The common sensor failures of motor motor rotor automatic rewinders and their solutions are as follows:

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, 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, servo motor temperature sensor failure:

Fault phenomenon: temperature sensor signal abnormality, disconnection, short circuit, aging, high ambient temperature, pollution or damage.

Solution: Check the temperature sensor connection line to ensure that there is no broken or short circuit; for aging sensors, need to be replaced; for high ambient temperatures, need to improve the working conditions of the sensor; for contaminated or damaged sensors, need to be cleaned or replaced.

8, Hall sensor failure:

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

Solution: Troubleshooting methods based on the speed observer, by analyzing the Hall signal and its jump along the signal to detect and compensate for Hall sensor failure.

The above solution provides the basic handling method for motor motor rotor auto reclaimer sensor failure, which helps to diagnose and repair the problem quickly to ensure the normal operation of the machine. ※ If you still can't solve the problem by the above ways and means, please contact the technical specialist of Xinhui Electromechanical Equipment Co., Ltd. through the page chat tool for help.
