What are the common sensor failures and their solutions for brushless motor motor fully automatic rotor into magnet machine?
The following are common sensor failures and their solutions for brushless motor motor automatic rotor into magnet steel machine:
First, the position sensor failure
Fault phenomenon:
Inaccurate position detection: the position sensor may not be able to accurately detect the position of the rotor or magnet, resulting in positional deviation of the magnet during installation, which affects the dynamic balance of the rotor and motor performance. This may be due to reduced sensitivity of the sensor, offset sensor mounting position, or external interference with the sensor.
Signal loss or instability: The position sensor may suddenly lose its signal or the signal strength may be unstable, resulting in the equipment being unable to accurately determine the position of the rotor or magnet, which in turn interrupts the incoming magnet operation or performs the wrong action.
Solution:
First check the installation position of the position sensor, use a gauge to check whether it has been offset, if so, adjust it to the correct position and recalibrate it.
Clean the sensing surface of the sensor and the surrounding environment to remove dust, oil or other contaminants that may interfere with the sensor.
Check the sensor's connecting wiring for breaks, shorts or poor contact, use a multimeter to check the conductivity of the wiring, and repair or replace damaged wiring.
For reduced sensor sensitivity, the sensor may need to be recalibrated. Use standard calibration tools and methods to adjust the sensor's sensitivity and detection range according to the equipment manual. If the sensor is aging or badly damaged, it should be replaced with a new sensor of the same model and recalibrated.
Second, the proximity sensor failure
Failure phenomenon:
Cannot be triggered normally: the proximity sensor cannot send out signals normally when the rotor or magnet is close to the predetermined position, resulting in the operation of the equipment into the magnet cannot be carried out according to the predetermined process, which may prevent the equipment from starting or stopping the action into the magnet.
False triggering: The proximity sensor may wrongly send out a signal when there is no target object approaching, resulting in false operation of the equipment, affecting the normal operation and productivity of the equipment.
Solution:
Adjust the sensing distance of the proximity sensor, according to the working requirements of the equipment, adjust the sensing distance to a suitable range through the adjustment knob on the sensor or modify the corresponding parameters in the control system of the equipment.
Check the installation position of the proximity sensor to ensure that it is firmly installed and the angle is correct, to avoid inaccurate sensing due to installation problems.
Eliminate external interference, such as electromagnetic interference, vibration interference or other environmental interference. Electromagnetic shielding measures can be used to shield the sensor wiring, the sensor away from the source of interference, while checking whether the grounding of the equipment is good, to reduce the impact of electromagnetic interference on the sensor.
Third, counting sensor failure
Failure phenomenon:
Inaccurate counting: the counting sensor may overcount or omit to count the number of rotors or magnets, resulting in the production of statistical data errors, affecting product quality control and production management.
No counting signal: the counting sensor can not output counting signal, so that the equipment can not count the number of magnets, affecting the monitoring of production progress and normal operation of the equipment.
Solution:
Check the counting settings of the counting sensor and adjust the sensitivity and counting mode of the sensor according to the size and shape of the magnet and rotor to ensure accurate counting.
For optical counting sensors, check its light source and receiving part, clean the lens and light source to ensure that the light can be transmitted and received normally; for mechanical counting sensors, check whether its triggering mechanism is working normally, such as checking whether the contact switch is flexible and whether the spring is normal.
Ensure that the power supply of the counting sensor is normal, use a voltmeter to check whether the power supply voltage is within the specified range; for unstable power supply, check the power line and power module, and repair or replace them. If the sensor is damaged, it should be replaced with a new counting sensor and tested to ensure accurate counting.
Fourth, the magnetic field strength sensor failure (if any)
Fault phenomenon:
Magnetic field strength measurement inaccuracy: for the need to monitor the magnetic field strength into the magnetic steel machine, the magnetic field strength sensor may have measurement errors, resulting in the inability to accurately determine whether the magnetic field strength of the magnet meets the requirements, affecting product quality.
No magnetic field strength signal output: the sensor may not output a signal, so that the equipment can not judge the magnetic field strength of the magnet steel, and thus can not complete the quality control steps.
Solution:
Check the calibration of the magnetic field strength sensor and recalibrate it using a standard magnetic field source to ensure that the measured value matches the actual magnetic field strength.
Check the connection line of the magnetic field strength sensor to see if there is any loose, broken or short circuit, repair or replace the damaged line.
If the sensor itself is damaged, it should be replaced with a new sensor of the same type, and re-calibrated and debugged according to the requirements of the equipment to ensure that the magnetic field strength can be accurately measured.
Through the timely processing and correct maintenance of the above common sensor failures, you can ensure that the sensor system of the brushless motor motor automatic rotor into the magnet steel machine works normally, improve the reliability of the equipment and the quality of production, to ensure that the process of entering the magnet steel is carried out smoothly.
