FAQ
DC motor knowledge points
1. Self-excitation conditions of shunt generator: ①There must be residual magnetism in the magnetic circuit of the motor; ②The excitation winding must be connected correctly, so that the current and magnetomotive force generated by the residual magnetism electromotive force have the same direction as the residual magnetism direction. ;③The total resistance of the excitation circuit must be less than the critical resistance.
2. The external characteristics of the shunt-excited generator U=f(I), the reason for the curve decline ①②The same as the above separately excited generator; ③The decrease of the excitation current causes the air gap magnetic flux and the armature electromotive force to further decrease.
3. Why can't the field winding be broken?
If the field winding is disconnected, If=0, the main magnetic flux will quickly drop to the residual magnetic flux, and the armature electromotive force will also drop to the residual magnetism electromotive force, so that the armature current Ia will increase rapidly. If the load is light load, then The speed of the motor will rise rapidly, causing "speeding"; if the load is heavy, the electromagnetic torque generated by the armature cannot overcome the load torque, and the motor may stall.
