DC motors are motors, direct current, the performance of these engines further improved by the use of permanent motors magnets ,
because they have become more common today in small engine
applications. These engines are lighter, more efficient and reliable.
Previously, the permanent magnets in small motors, but used by the new
technologies have made it possible for high intensity permanent magnets
such as Neodymium magnets have proven useful in the development of
compact high-power engines without using magnetic coils . The
construction technology of these engines takes place DC motor with
permanent magnets.
The
advantages of this engine can be developed as models to understand,
control speed and torque are simple and the drawings are still going
cheap. If the field is generated by permanent magnets, these motors are
subjected to a permanent magnet DC motor. These engines are preferred
because of its cost, average capacity and the variety offered in the
choice of demand for small engines that are up to 3 HP may increase in
most DC motors. In particular, we can say is that it is all about
magnets and magnetic theories. The universal law of the magnetic "poles
repel and opposites attract between equals." Most DC motors with
permanent magnets work on the same principle, lead to repulsion motors
to rotate the motor and speed, yet can be done from 1RPM up to 500 rpm
or more, depending on capacity magnets.
Speed,
torque DC motor permanent magnet, the voltage or the effective
resistance of the armature circuit can be controlled. There are many
advantages of permanent magnet DC motor, the lower production costs are
smaller, more efficient, less noise, less television and radio
interference. There are some disadvantages as well as heat shielding
magnetic charge when the engine design is defective, then brush can
cause false move and they are limited in size.
There
are many applications of this engine, for example, a DC motor in a
windshield wiper 12V PM, door locks, power windows can be used by lock
braking systems ants, fans and other accessories for cars, can be used
in toys and electric toothbrushes as well. If the motor is large, then
for the production of energy for the benefit of electricity production
house and will be cheaper than solar energy can be used. Thus, by
collecting useful information on current permanent magnet motors, you
can create your own DC motor developed.
