To analyze the reason for the alternating positive and negative rotation of the motor, the following methods can be used: 1. * * Check the internal parts of the motor ** - Check whether there is a short circuit or an open circuit in the motor's winding, which can be detected by the relevant electrical test instrument. If there was a fault in the winding, it could affect the magnetic field and the direction of the current, causing the motor to rotate in both positive and negative directions. - Check the degree of wear of the brush. If the brush is seriously worn, it may cause the working state of the motor to be unstable, thus affecting the direction of the motor. - It was necessary to measure whether the resistance of the motor was normal. An abnormal resistance of the motor could cause the motor to run abnormally, resulting in alternating positive and negative rotation. 2. * * Investigate external interference factors ** - Observe whether the power supply voltage is stable. Unstable power supply voltage may cause the motor to rotate in both positive and negative directions. A voltage meter can be used to monitor the power supply voltage. - Consider whether the motor and other equipment affect each other. If there is electromagnetic interference or electrical connection problems between the motor and other equipment, it may cause it to alternate forward and backward. 3. * * Observe the running state of the motor ** - Pay attention to whether there is any strange noise or vibration when the motor is working normally. These abnormalities may indicate that there is an internal fault in the motor or external interference, which is the potential cause of the alternating positive and negative rotation of the motor.

Does Shanghai 2022 kindergarten registration require points?

In the registration of Shanghai kindergarten in 2022, if you want to enter a public kindergarten and have the right to choose a school, you need to have 120 points in your residence permit. If you don't have 120 points in your residence permit, but your residence permit meets the age requirements, you can let your children move to private kindergarten and a few public kindergarten. Those who do not have a residence permit or have a residence permit that does not meet the age requirements can allow their children to move to a small number of private kindergarten and a few public kindergarten to study; the situation of holding a flexible employment registration certificate for three years is the same as the situation of holding a residence permit with less than 120 points.
