Commutator is a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit. In a motor, it applies power to the best location on the rotor, and in a generator, picks off power similarly. As a switch, it has exceptionally long life, considering the number of circuit makes and breaks that occur in normal operation
.A commutator is a common feature of direct current rotating machines. By reversing the current direction in the moving coil of a motor's armature, a steady rotating force is produced. Similarly, in a generator, reversing of the coil's connection to the external circuit provides unidirectional (i.e. direct) current to the external circuit
A commutator consists of a set of contact bars fixed to the rotating shaft of a machine, and connected to the armature windings. As the shaft rotates, the commutator reverses the flow of current in a winding. For a single armature winding, when the shaft has made one-half complete turn, the winding is now connected so that current flows through it in the opposite of the initial direction. In a motor, the armature current causes the fixed magnetic field to exert a rotational force, or a torque, on the winding to make it turn. In a generator, the mechanical torque applied to the shaft maintains the motion of the armature winding through the stationary magnetic field, inducing a current in the winding. In both the motor and generator case, the commutator periodically reverses the direction of current flow through the winding so that current flow in the circuit external to the machine keep in one direction
Jiangsu Angu Electric Appliances Co.,Ltd, is established in 1994。 Now we can design and manufacture various kinds of commutators used in power tools,automobiles and home appliance. There are thousands of commutator types in our factory including three serizes of JZQC,DZQC and QZQC.Non-standard products of various models can also be designed and manufactured upon special requirements. We use complete set of automatical equipments for drawing,stamping, moulding, drying and checking, which ensures the precision and high quality.And unique equipments for testing and chemical examination,which ensures the high quality.
