direct current (DC) rotating machines In motors, commutators apply power to the best location on the rotor. A steady, rotating force (torque) is produced by reversing the current direction in the moving coil of the motor's armature.... Here are three quick checks you can perform with a volt/ohm meter to test a DC motor armature winding to determine if a motor armature is functioning properly.

north, every half turn. The commutator in this motor is made by folding the leads of the electromagnet to form 2 zigzags. When the commutator The commutator, which is the other part of the armature, is just a fancy switch for the electromagnet. It turns the electromagnet on and off, and STEP 2. Makino the Com mutator - the Motor's Switch must sand the paint off the wire in order to make an...
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

How To make a commutator? Yahoo Answers
The armature windings of your DC motor will have very low resistance. Too low, in fact, to accurately measure with an ohmmeter connected directly to the commutator terminals, because the contact resistance between the meter probes and terminals will be a … how to clean silver filligreejewelry A DC motor uses a direct current rather than an alternating current. The invention of the electrical motor is derived from Faradays Law of electromagnetic induction. When you move a magnet close to an electrical conductor a current will be present in the conductor..

  • Common commutator wear patterns. It's relatively easy to judge DC motor performance by looking at the commutator. During normal commutation, brush current vaporizes some copper molecules, depositing a uniformly tan to charcoal-brown copper-oxide film (about 2 in.310-7 in. thick) on the commutator.
  • How DC Motors are made and how they work - A close look on the rotor. The 3 electromagnets (armature) can be seen. Also, you can see the commutator, and -if you look close enough- …
  • 8/08/2008 · A commutator typically consists of a set of copper segments, fixed around part of the circumference of the rotating part of the machine (the rotor), and a set of spring-loaded brushes fixed to the stationary frame of the machine.
