Basic knowledge about the motor


17. During normal excitation, the power factor of the synchronous generator is equal to 1; keep the output active so that the excitation current is less than the normal excitation (under excitation), then the nature of the direct-axis armature reaction is magnetically assisted; When the excitation current is greater than the normal excitation (overexcitation), the nature of the direct-axis armature reaction is demagnetized.


18. In DC motors, the iron loss is mainly present in the rotor core (armature core) because the stator core magnetic field is essentially unchanged.


19. In a DC motor, the first pitch y1 equals the number of slots between the first and second sides of the component. The composite pitchy is equal to the number of slots between the upper edge of the two elements in series.
