What Causes An Electric Motor To Overheat. One Root Cause of Insulation Failure Bearing and winding failures are the most common motor failures. High current draw could be caused by 1 the motor being too small for the application 2 the motor is the correct size but something in the application is not functioning correctly or 3 incorrect voltage.
Too many volts or too few volts can be damaging to a motor. When this occurs the heating element can. When your motor doesnt have the right voltage support it needs to work harder to perform which causes parts to overheat.
While too low voltage will decrease the electromagnetic torque and increase copper loss.
The wrong voltage supply. Motors come in a range of sizes. Overheating can cause the RC motor to fail have poor performance or even cause a short and damage or destroy the ESC and the batteries. High current draw could be caused by 1 the motor being too small for the application 2 the motor is the correct size but something in the application is not functioning correctly or 3 incorrect voltage.
