General introduction of permanent magnet motor:
- Permanent magnets are materials where the magnetic field is
generated by the internal structure of the material itself. Inside
atoms and crystals you have both electrons and the nucleus of the
atom. Both the nucleus and the electrons themselves act like little
magnets, like little spinning chunks of electric charge, and they
have magnetic fields inherent in the particles themselves. There's
also a magnetic field that's generated by the orbits of the
electrons as they move about the nucleus. So the magnetic fields of
permanent magnets are the sums of the nuclear spins, the electron
spins and the orbits of the electrons themselves. In many
materials, the magnetic fields are pointing in all sorts of random
directions and cancel each other out and there's no permanent
magnetism. But in certain materials, called ferromagnets, all the
spins and the orbits of the electrons will line up, causing the
materials to become magnetic. This would be your normal iron,
cobalt, nickel. Permanent magnets are limited by the structure of
the material. And the strongest magnetic field of a permanent
magnet is about 8,000 gauss. The strongest magnets here at the
Magnet Lab are 450,000 gauss, which would be almost 50 times
stronger than that.
The difference between Permanent Magnet AC (PMAC) motors differ from AC Induction motors:
- In the broadest sense, the major difference is in the rotor itself.
In a squirrel cage induction motor, current is induced into the
rotor from the field (stator) through the air gap, and conducted
through aluminum (or other material) bars, which are most often die
cast in the slots of the rotor laminations. In the case of a PMAC motor, the rotor itself contains permanent
magnet material, which is either surface-mounted to the rotor
laminations stack or embedded within the rotor lamination. In either topology,
electrical power is supplied through the stator windings.
The benefits of PMAC motor versus AC Induction:
- Permanent Magnet AC motors are inherently more efficient due to elimination of rotor conductor losses, lower resistance
winding and “flatter” efficiency curve. Due to their synchronous
operation, PMAC motors offer more precise speed control. PMAC motors provide higher power density due to the higher magnetic flux as compared with induction
machines. Finally, Permanent Magnet motors generally operate
cooler, resulting in longer bearing and insulation life.
