Permanent magnet dc motor can be divided into permanent magnet brushless dc motor and permanent magnet brushless dc motor.Permanent magnet dc motor is a kind of dc motor which USES permanent magnet to establish magnetic field.
high speed N52 brushless dc motor magnets
Dc machine is needed magnet, mainly use ndfeb magnetic steel material, most are tile, ring, can be used in a variety of different
motor.Motor magnet has a certain temperature tolerance requirements, generally need more than 120 degrees of temperature
tolerance, so most of the magnet using SH series.
To magnetize a material or add magnetism to an undermagnetized magnet.Generally, magnetic objects to be magnetized are
placed in a magnetic field created by a coil through which direct current passes.The direction of magnetization can be divided into
thickness magnetization, radial magnetization and so on.When affected by external energy, such as heating and impact, the
direction of the magnetic distance of each domain will become inconsistent, and the magnetism will weaken or disappear, which
will demagnetize. In order to retain the original properties, magnetization is required.
At present, the demand for motor magnet is very large, magnet is its core component, in micro special motor, small and medium-sized motor and large generator, can use ndfeb permanent magnet material.
