WebApr 29, 2024 · Second, a railgun's operation is not analogous to a DC motor. It is, however, analogous to an induction motor which also doesn't have magnets, just without the induction part. An induction motor induces a current on the rotor whereas a a railgun directly passes a current through the projectile. WebHow does this simple DC Motor work? Its essentially a coil with a magnet connected to a battery. So we built it and it worked. The main question is, why? I thought that the motor had to have a brush or something to change the direction of the magnet or the coil. Without it, the torque would change to the opposite direction once it flipped over ...
WebThe applied DC current does not have any time structure to it, and so does not set the turning rate of the motor. The rate at which the current can switch directions in the electromagnet and the force of attraction to the permanent poles are directly related to the applied DC voltage. WebMotors consist of loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts a torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process. Figure 20.23 shows a schematic drawing of an electric motor. Figure 20.23 Torque on a current loop.

To go any further, the poles of the electromagnet must flip. The brushes, as the rotor spins, make contact with the stator, flipping the magnetic field and allowing the rotor to spin a full 360-degrees. dune spice wars cestinaWebConstruction of a Commutator. A commutator is built with a set of contact bars and is set into the revolving shaft of a DC machine allied to the armature winding.
