popular design waste stator rotor and commutator with high output

• Chapter 19 Motion-System Power Management Power

   · The SRM has no brushes or permanent magnets and the rotor has no electric currents (Fig. 19-4). Instead torque comes from a slight misalignment of poles on the rotor with poles on the stator. The rotor aligns itself with the magnetic field of the stator while the stator field stator windings are sequentially energized to rotate the stator field.

• Alternating Current MotorsAAST

  • The reason for this requirement is that the current in the stator windings must be maintained at a certain design value for the magnetic induction process (to the rotor) to work. • Most motors are designed to operate at 60 Hz and 120 V (or 240 V) so the stator is wound to create the proper magnetic field with those conditions.
