Alternative to Saltwater Testing for Electric Motors—Winding Point Damage Detection

Motor (pinhole) salt water test is a test method commonly used by motor manufacturers. The usual method is to use pure water or boiled water to make a saline solution with a concentration of about 0.2%,

Reasons and solutions for damage to the test driver board (circuit board) of the brushless DC motor

The DC internal drive brushless motor is composed of the motor and the built-in driver. In order to reduce the cost and simplify the circuit design of the built-in driver board, a relatively economical method is often used to realize the motor drive.

The significance of the back EMF of the brushless DC motor

When a BDLC motor turns, each winding develops a back electromotive force voltage (BEMF) which, according to Lenz's law, is in the opposite direction to the main voltage supplied to the windings.
