1. The current of the single-phase transformer at no load is different from the main magnetic flux, and there is a phase parity aFe, due to the presence of iron current. The no-load current is a spire waveform due to the large third harmonic in it.
2. The flow in the armature winding of the DC motor is also the communication current. However, the current flows in the excitation winding. The excitation methods of DC motors include separate excitation, parallel excitation, series excitation, compound excitation, etc.
3. The expression of the back EMF of the DC motor is E = CE F n; The expression for electromagnetic torque is Tem = CTFI.
4. The number of parallel branches of the DC motor is always in pairs. The number of parallel branches of the communication winding is varied.
5. In a DC motor, the components of a single stack of windings are connected in series by stacking one on top of the other. Whether it is a single-wave winding or a single-stack winding, the commutator connects all the components in series to form a single closed loop.
6. Asynchronous motor is also known as induction motor, because the rotor current of the asynchronous motor is generated by electromagnetic induction.
7. When the asynchronous motor is started at a step-down step, the starting torque decreases, and the starting torque decreases proportionally to the square of the starting current of the winding.
8. When the amplitude and frequency of the primary side voltage remain unchanged, the fullness of the core of the transformer does not change at all, and the excitation reactance does not change at all.
9. The short-circuit characteristic of the synchronous generator is a straight line, and the magnetic circuit is not full when the three-dimensional symmetrical short-circuit; In the case of a three-dimensional steady-state short circuit, the short circuit circuit is a pure demagnetized straight axis component.
10. The current in the excitation winding of the synchronous motor is the DC current, and the excitation methods mainly include excitation generator excitation, stop rectifier excitation, rotary rectifier excitation, etc.
