Stressful mechanical, environmental, and electrical operating conditions can all cause electric motor failure. Electrical failures are winding failures caused by an open contactor, bad connection, blown fuse, excessive heat, electrical overload, or broken power lines.
What kills an electric motor?
Motors are commonly killed by one of two things: insulation failure or bearing failure. The dramatically simplified cause of these failures is heat and/or excessive voltage.
How long do electric motors last?
Some manufacturers estimate 30,000 hours, while others state 40,000 hours. Some will say “it depends.” One thing is clear—a motor should last much longer with a conscientious motor systems maintenance plan than without one. Motor life can range from less than two years to several decades under particular circumstances.
What causes an electric motor to overheat?
The most common causes of overheating include: An unsuitable motor: Motors come in a range of sizes. … The wrong voltage supply: Too many volts or too few volts can be damaging to a motor. When your motor doesn’t have the right voltage support, it needs to work harder to perform, which causes parts to overheat.
Do electric motors slow with age?
Generally electric motors don’t slow their speed during years or decades. You have only to check bearings, and brushes, only for brushed motors. Most electric motors, whether AC or DC, fail after time for reasons that may not be electrical in nature.
