AIP's latest motor test solution news and motor industry news.

Understand all the university questions of electrical machinery in one article, from principle, classification to application

An electric motor is a device that converts electrical energy into mechanical energy. It uses the energized coil (that is, the stator winding)

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%,

GBT 12350-2022 "Safety Requirements for Small Power Electric Motors" New National Standard Approved and Released

The new national standard GB/T 12350-2022 "Safety Requirements for Small Power Motors" has been approved and released, and will be officially implemented in November 2022 this year.

Explain the structure of stepper motor in detail

Stepper motor is a special motor used for control. Its rotation is performed at a fixed angle (called "step angle") step by step.

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 development history of rare earth permanent magnet motor

How to test the back electromotive force of permanent magnet synchronous motor?

According to the law of electromagnetism, when the magnetic field changes, an induced electromotive force will be generated in the nearby conductor,

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.
