MOTORS | AC Brushless Motors
AC brushless motors use the induction of a rotating magnetic field in the stator to turn the rotor and stator at the same rate. Like DC motors, these are permanent-magnet synchronous motors, or PMSMs, that rely upon magnets built into the rotor. AC models specifically use electromagnets and rely on an integrated power inverter, rectifier, and sensor.
Issues connecting to moving armature are avoided by using a fixed one with permanent magnets in the rotor. The lack of brushes in these motors also increases their lifespans, makes them cleaner and quieter, and reduces wear and tear. Potential problems with centrifugal forces are reduced by avoiding windings on the rotor and eliminating the need for active cooling.
