What is the Temperature Resistance of Brushless Motor Magnets? The brushless motor adopts electronic commutation, the coil does not move, and the magnetic pole rotates. Brushless motors use a set of electronic equipment to sense the position of permanent magnet poles through Hall elements. Based on this perception, electronic circuits are used to switch the [...]
Magnetic Particle Examination Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as “a term applied to materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities [...]
How to Determine Polarity of Magnets You might have heard the phrase “opposites attract.” While perhaps not always the best advice for relationships, this cliché is the rule of thumb for magnet polarity. Since we inhabit a giant magnet (Earth), understanding magnet polarity on a small scale will help you understand the larger magnetic field [...]
Testing Magnetic Field Strength With a Gaussmeter Calculate the baseline or original voltage. This can be done using a gaussmeter, also known as a magnetometer or an EMF detector (electromagnetic field detector), which is a hand-held device that measures the strength and direction of a magnetic field strength. They are readily available to buy and [...]
