Electric motors have become the pillars of modern civilization, found in every home, factory, or even workshop, and everywhere. Electric motors convert electrical energy into mechanical energy. That is, through electric motors, you can rotate the washing machine drum, or even the blender, or the blades in the fan, and the like. But the question here is: What are the causes of high temperatures in electric motors? This is what will be learned.
Causes of electric motor overheating
Below we explain the reasons for the high temperature of electric motors, which are as follows:
1. Place the engine in an unventilated area.
The primary reason for electric motors to overheat is this, and this particular reason is often overlooked. A motorized blender should not be placed above an oven that emits high heat. This is also the case in workshops or factories where there is a heat source.
In addition, when the motor is directly exposed to the sun’s heat, this will cause the motor’s temperature to rise.
You must know that the engine temperature will certainly rise above the required limit, which will cause the thermal sensor to disconnect if it is present. However, if it is not present, this will lead to engine damage over time.
2. High voltage
It is worth noting that the voltage, or as some know it, that the motors operate on has become fixed, meaning that it must not increase or even decrease.
If the voltage decreases, the motor's performance will be affected, while if the voltage increases, this will result in an increase in the motor's temperature, which will eventually lead to the insulation on the motor's coils collapsing and causing it to be damaged.
So if you find that the engine is getting hot, it is best to measure the voltage reaching it.
3. Engine overload
The motor has a specific power rating, but when you load it with more than its rated power, it will draw more amps, which will cause the motor to overheat and eventually burn out, or the thermal protection inside the motor may trip.
4. The presence of an obstacle that prevents the engine from rotating.
Most of the time there is an obstruction, which causes the motor to not spin, which results in the motor overheating and will draw high amperage until it burns out completely.
5. Damage to the axle bearings
One of the reasons for electric motors to overheat is damage to the axle bearings, or even the axle not rotating freely, or there may be a warp in it. Another reason for overheating is an imbalance between the mechanical parts of the motor.
6. The engine is running without cooling.
There's no doubt that every electric motor has its own cooling method. For example, there's a fan inside the motor whose purpose is to cool the engine. If that fan stops for any reason, its blades will be damaged, meaning the fan will no longer be able to perform its function. This results in an increase in the engine's temperature.
In addition, some engines rely primarily on vents. If they become blocked or even cooled by the engine coils, this results in the engine overheating. This is one of the causes of electric motor overheating.
What to do when your car engine overheats?
You must follow the following tips:
- You should know the warning signs, and you should monitor the temperature gauge while driving, so you can know when the temperature is rising or falling.
- You should turn off the air conditioner.
- Do not press the brakes.
- Pull the cover open
When is a car overheating dangerous?
When it rises suddenly, you should not continue driving, and this is when you should measure the temperature.
What causes a high body temperature?
There are several reasons, including:
- Taking certain medications, including antibiotics and medications used to treat high blood pressure or even epileptic seizures.
- heat exhaustion
- occurrence of a cancerous tumor
- or bacterial infection
- viral infection
- Inflammatory conditions including rheumatoid arthritis, which is an inflammation of the lining of the joints (synovium).
- colds and flu
Causes of home water motor malfunctions
There are many faults that cause the motor not to work, including:
1. High temperature
You find that pumps basically rely on heat generation, and this causes an increase in temperature.
You can solve this problem by maintaining the appropriate temperature for this matter for the longest possible time.
2. Dust and dirt
The pump motor sucks in all the dust, dirt, and small particles, which can damage the pump and cause it to malfunction.
3. Power supply fault
The pumping rate of electricity causes a harmonic current, but if there is a defect in the pumping, this results in an imbalance in the current inside the pump and also the voltage.
4. Humidity
High humidity in the air can cause engine malfunction and failure, and over time, it can cause engine parts to wear out.
5. Low water level
When the water level inside the pump drops, it fails to draw the required amount of water, which results in a malfunction in the water pumping process during operation.
Causes of high temperature of the shovel
- Dirt on the front of the radiator
- Dirt and the like can accumulate inside the water pockets, and here it becomes an insulator, preventing heat from either transferring or escaping.
- The appearance of an obstruction in pipes or even water pockets
- The ignition time may be late or early.
- Lack of water in the system, which is due to the presence of seepage
Normal generator temperature
Many people believe that the basic operating temperature for an internal combustion engine is between 87°C and 105°C. However, you should keep in mind that the temperature is determined by itself.
Reasons for washing machine motor overheating
We will learn about the reasons for the washing machine motor overheating as follows:
1. Dirt accumulation
Dirt can enter through the motor start switch, causing the moving contacts to close, disrupting motor start-up, or preventing the washing machine door from closing.
2. Overloading
Overloading your washing machine can cause wear and tear, and can also cause the machine's bearings to rupture. Overloading can also cause the motor to overheat.
Causes of electric motor fire
We will present to you the reasons for electric motor burning as follows:
1. Engine overload beyond the specified limit
There is no doubt that every electric motor is designed with a limiter, and here you must not exceed that limit, as when the load on the motor increases, this also results in an increase in temperature, which results in the motor coil burning out.
2. Running the engine for long periods without stopping
There are engines that you can run for the longest possible time, and there are others that cannot be run for long periods, so you should avoid running the engine for long periods to avoid hacking it.
3. Engine overheating
We agree that overheating is the main reason for burning out electric motor coils.
You should take into account that the coils may overheat due to overload or there may be an obstacle preventing the motor from rotating.
4. Files are exposed to vibration or frequent shocks.
Many people ignore the vibration that occurs in the engine while it is running, and they also do not pay attention to the shocks that occur. This results in an imbalance in the engine, which causes the electric motor to catch fire.
5. High source voltage
An electric motor is designed to operate at a specific voltage and current, but if there is an increase in the voltage of the source that powers the motor, then it is very likely that the increased current passing through the coils will cause overheating and even combustion.
Therefore, you must ensure that a voltage protection device is installed to prevent over- and under-voltage, and that all electric motors are disconnected in any case, whether the voltage is high or low.
After mentioning the most common causes of electric motor overheating, it's worth noting that overheating is often caused by a problem, which can lead to complete engine failure. Therefore, don't ignore an overheated electric motor, as it will eventually burn out.
