Commutator series motor is a DC permanent magnet on the motor in order to enable a sustained turn down the original parts.
Structure, the commutator contact pads surrounded by a few round, are connected to each tap on the rotor, called the brush outside the connected electrodes in contact with, and only contacted one of the two.
Principle is that when the current through the coil, will the role of the permanent magnet by attracting and repulsive turning, and the magnet when it is to balance the original through a power line compared with the corresponding contacts on the commutator and electric Shuafen left, and brush connected to the line driving force of the group produced the corresponding contacts on the coil, so stop repeating down the DC motor to turn up.
If there is no commutator role that the motor can only turn less than a half-circle on the card is dead, can only be used as power brakes.
Commutator of two copper semi-ring, the middle gap. By the commutator with brushes to effect change, to change the current direction.
