What Are The Reasons For The Miniature Water Pump Motor To Burn Out

The small water pump will operate for an excessive amount of time without water if the lift is lower than the value listed on the pump's nameplate, and starting the pump with a load could harm the motor. Determine whether the bearing (mechanical failure) or the coil is to blame when the motor burns out first (electrical failure). Overcurrent is the principal cause of coil burning faults. Check to see whether the voltage during operation deviates too much from the rated voltage since sometimes it might be too high or low and cause the coil to heat up and short circuit. Let me explain why the motor on the micro pump burns out.

1. There is an issue with the motor's heat dissipation. The tiny water pump typically has a water-cooled shell, whereas the motor coils typically have an air-cooled shell. Both air-to-air and air-to-water heat exchangers are used to cool the majority of large motors. The coil cannot release heat if the cooling water (air) is taken off, and the coil risk burning.

2. The motor overloads due to the mechanical failure of the pump, and the resulting high current damages the coil.

3. The tiny water pump is overloaded, causing the motor to operate for an extended period of time at the rated current or above it. It should be avoided starting the equipment with load or full load operation since the motor's starting current 

4. The motor operates in a damp environment. Check the coil's phase-to-phase insulation and ground insulation before turning on the motor. Different voltage levels have various insulating requirements. The motor's waterproofness and moisture-proofness should be taken into consideration while it is operating.

The head of the micro pump is used to overcome the height and resistance. When the high-lift pump works at the high-lift point, its flow rate is the flow rate at the design point. If it works at a low-lift point, it is equivalent to the reduction of the outlet resistance of the pump. At this time The flow rate of the centrifugal pump will increase, the motor will be overloaded, and the motor will be burned to a certain extent.

The above are the reasons why the water pump burns the motor introduced by Vshida Micro Motor. For more information, please contact us.
