  • MOTOR CIRCUITS AND CONTROL Applied

    A contactor is a large relay, usually used to switch current to an electric motor or another high-power load. Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts. If the series-connected heaters get too hot from excessive current, the normally-closed overload contact will open, de-energizing the contactor

  • How to Build a Vibration Motor Circuit

    When simply powering the vibration motor directly with DC voltage, then no diode is necessary, which is why in the simply circuit we have above, we only use a voltage source. The 0.1µF capacitor absorbs voltage spikes produced when the brushes, which are contacts connecting electric current to the motor windings, open and close.
