  • Controlling DC Motors

    To control the direction, the polarity of the motor is reversed. To control the speed, the input voltage is varied using pulsewidth modulation. Direction Control. To control a DC motor from a microcontroller, you use switching arrangement known as an H bridge. It looks like this: When switches 1 and 4 are closed and 2 and 3 are open, voltage flows from the supply to 1 to the motor to 4 to ground.

  • How Do You Read an Electrical Ladder Diagram?

    Quick Answer. To read an electrical ladder diagram, first identify the two rails that signify the supply power, and then locate the rungs that portray all of the control circuits connected to the power source. The L1 designation typically refers to the hot conductor on the 120-volt AC supply, and the L2 designation typically refers to the neutral,

  • The relationship between voltage and DC motor output speed

    Dec 06, 2015The operation of a DC motor is relatively straightforward. A coil is placed in a magnetic field, and when an electric current passes through the coil, a torque is produced, causing the motor to turn. The entire process is driven by applying electrical power to the coil, with the source voltage having a direct relationship to the motor's output speed.
