    How to fire a DC motor

    In addition to the standard operation of DC motors in use, we also need to master some basic common sense, so even if there is a problem, we can deal with it in a timely manner, avoiding a lot of unnecessary trouble, so today I will tell everyone It is about the fire prevention measures that we need to pay special attention to. This is very important. I hope everyone can study it carefully.

    1. No debris should be stacked around the machine. To avoid causing a fire, a proper distance should be maintained between the DC motor and its starting device and combustibles.

    2. After the maintenance and the power outage for more than 7 days, the insulation resistance of the motor should be measured before starting to prevent the motor from being damaged due to damping of the insulation, interphase short circuit or ground breakdown.

    3. During start-up, the specified number of start-ups and start-up interval shall be strictly implemented, and frequent start-ups shall be avoided as far as possible, so as not to cause the stator windings to overheat and catch fire.

    4. During the operation, the current and voltage must not exceed the allowable range. The temperature, sound, vibration, and shaft series of the DC motor should be normal and free from odor.

    5. When the motor is running out of phase, the power supply should be cut off immediately to prevent the motor from heating and catching fire due to the lack of phase operation.

    6. Once the DC motor catches fire, immediately cut off the power supply and use a carbon dioxide, carbon tetrachloride, "1211" fire extinguisher and steam fire extinguisher for electrical equipment to extinguish the fire.

    Fire awareness is something we need to know from a young age, so it is equally important for DC motors and other equipment, so we must pay more attention to safety awareness issues during the use and learning process.
