How to judge the broken rotor bar

Broken rotor bars are a form of motor failure that occurs in squirrel-cage motors.

Dynamometer Principle

Before learning the principle of the dynamometer, let's first understand why we use the dynamometer. The principle of the dynamometer is the theoretical basis for us to achieve the purpose of the dynamometer.

Brushless Motor Performance Test

The brushless motor performance test is a necessary test before the motor leaves the factory, and the motor performance directly affects whether the motor can run normally.

How to test the brushless DC motor

Due to its electronic commutation, drive control and other characteristics, the DC brushless motor will add a circuit board test compared to the AC motor,

How to measure the quality of the motor stator?

To measure the quality of the motor stator, it is necessary to confirm whether the various parameters of the motor stator are normal.

What is new energy vehicle motor testing？

With the development of society and the support of national policies, the concept of green environmental protection has been deepened,

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.
