using a commutator?
1. It is only accustomed to small motors composed of transistors, which are used for electric power-ineffective DC motors. Large capacity is often referred to as a non-commutative motor or synchronous motor self-controlled inverter frequency conversion system. There is no switching power motor to provide DC power, which is called DC non-switching motor; there are also useful AC power, which is called AC non-switching motor or non-switching motor interchange system. In high-capacity non-commutative motors, the inverter is mostly installed, so it is also called a crystal gate electric motor.
2. Transistor motors can also be classified as AC motors. The characteristics of sliding contact, relative resistance and contact resistance are also required. In the basic case, graphite is a bit of raw material. The result of the directional device is still connected to the current between the proportional movements. Ordinary obliterators of electric motors, as well as direct tram and electric cars. The shape of the direction device is different. Most of the rectangles used on motors are placed on the brush holder. There is some pressure between the direction finder and the switch or slip ring. The large switch structure is very complicated, and the small wiper is very simple. The current derivation of the direction finder is also different. Some of the wiring on the steering machine is usually led by an elastic conductive battery. Most of the modified materials are made of graphite, that is, to increase the electrical conductivity or to make graphite containing copper. The conductivity of graphite is soft and soft. After pressing the directional device on the brush, you should move by yourself. In this way, you can continuously wear the converter under spring pressure and continue to contact the rectifier or collector ring. Several sides of the direction guide and gaps between the inner walls of the brush should be left.
3. The commutator mainly presents corrections to ensure that the direction of the electromagnetic torque is always maintained. When it turns to balance the magnet, the original wire is separated from the brush of the brush and the motor will turn.
4. The commutator is a corrective effect, its function is to make the current direction of the current in the winding system to ensure that the direction of the electromagnetic torque always remains unchanged. In a generator, the switching of direction can bring the interchange potential in the component into the DC potential of the inter-brush bridge; in electrical thought, it can add an external DC current to the AC current in the component, thereby producing a constant directional torque.
5. When the coil passes through the current, under the action of the permanent magnet, it will rotate by attraction and alone. When it turns to the magnetic balance of the magnet, the original wire will be divided into brushes from the corresponding directional device. Leave, the brush is connected to the group corresponding to the coil that conforms to the driving force, so that the DC motor rotates continuously, and the DC motor rotates. If there is no way to change the directional device, the motor can only be stuck in less than half a circle and can only be used as an electric brake.
