What happen when the spark comes out the motor?

When a spark occurs from an electric motor, it typically indicates a problem, such as a short circuit, worn brushes, or electrical arcing. This can lead to overheating, damage to the motor components, or even a fire hazard if not addressed promptly. It's crucial to shut down the motor and investigate the cause of the spark to prevent further damage or safety risks. Regular maintenance can help minimize the occurrence of such issues.
