When an electric motor stops rotating in a vacuum cleaner, there could be several reasons for this issue. The most common ones include:
Overheating: Electric motors generate heat during operation, and if the motor gets too hot, it may have a built-in safety mechanism that shuts it down to prevent damage. Overheating can occur due to various reasons, such as blocked airflow, a clogged filter, or the motor being overloaded.
Faulty power supply: If there is an issue with the power supply, such as a tripped circuit breaker, blown fuse, or loose electrical connection, the motor may stop receiving electricity, causing it to stop rotating.
Motor failure: Electric motors can fail over time due to wear and tear, manufacturing defects, or other internal issues. If the motor's internal components or windings are damaged, it can lead to a complete failure.
Mechanical obstructions: The motor's rotating shaft may get stuck due to debris, dirt, or foreign objects entering the motor assembly or blocking the vacuum cleaner's moving parts.
Now, to fix the issue of the electric motor not rotating in a vacuum cleaner, you can follow these steps:
Check power supply: Ensure that the vacuum cleaner is properly connected to a functioning power outlet. Verify that the circuit breaker hasn't tripped and that the fuse, if applicable, is not blown.
Cooling off: If the motor is hot to the touch, turn off the vacuum cleaner and let it cool down for some time. Check for any obstructions or clogs that might be hindering airflow around the motor or air intake.
Remove obstructions: Inspect the vacuum cleaner's rotating brush and motor assembly for any debris or foreign objects that might be causing mechanical obstructions. Clear them out if found.
Clean the filter: A clogged filter can reduce airflow and cause the motor to overheat. Clean or replace the filter as per the vacuum cleaner's manufacturer instructions.
Avoid overloading: Be mindful of not overloading the vacuum cleaner by trying to pick up large or heavy objects that it's not designed to handle.
Motor repair or replacement: If none of the above steps resolve the issue, the motor might need repair or replacement. This typically requires the expertise of a qualified technician, as electric motor repair can be complex.
Remember, safety is crucial when dealing with electrical appliances. Always unplug the vacuum cleaner before attempting any repairs and refer to the manufacturer's guide or seek professional assistance if you're unsure about the problem or the solution.
