  2. Damper (flow) - Wikipedia

    en.wikipedia.org/wiki/Damper_(flow)

    In this way, applying power to the "open damper" terminal causes the motor to run until the damper is open while applying power at the "close damper" terminal causes the motor to run until the damper is closed. The motor is commonly powered from the same 24 volt AC power source that is used for the rest of the control system. This allows the ...

  3. Motor capacitor - Wikipedia

    en.wikipedia.org/wiki/Motor_capacitor

    A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [ citation needed ] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor ).

  4. Centrifugal switch - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_switch

    A variation of the centrifugal switch used a changeover contact to ensure that the auxiliary windings remain in the circuit through a running capacitor. These motors are called two-value or capacitor start capacitor run motors. Centrifugal switches are found in many clothes dryers, supplying power to the motor in parallel with the start switch ...

  5. Electric motor - Wikipedia

    en.wikipedia.org/wiki/Electric_motor

    An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

  6. Fan (machine) - Wikipedia

    en.wikipedia.org/wiki/Fan_(machine)

    Standalone fans are usually powered by an electric motor, often attached directly to the motor's output, with no gears or belts. The motor is either hidden in the fan's center hub or extends behind it. For big industrial fans, three-phase asynchronous motors are commonly used, may be placed near the fan, and drive it through a belt and pulleys.

  7. Blowing engine - Wikipedia

    en.wikipedia.org/wiki/Blowing_engine

    As blast furnaces re-equipped after World War II, the favoured power source was either the diesel engine or the electric motor. These both had a rotary output, which worked well with contemporary developments in centrifugal fans capable of handling the huge volumes of air. Although the reciprocating steam blowing engine continued where it was ...
