  1. Good Evening,

    I want to know the fundementals behind 2 speed control in the motor. Will it be applicable for slip-ring motors also?

    Thanking you,

  2. please tell me fundamental of 2 speed 1 direction of 3 phase motor,what is S1 AND S2 and its working.kindly please tell me

  3. please is it the normal stop and start button can be use for the control and many stop and start button required for this??????

  4. Hi guys. Please explain to me if I must really put a contactor on my 3 phase motor. And can I not just run it straight without a contactor. 2 contactors burned out in one day but nothing wrong with motor. motor is a hi low 3 phase motor on a air compressor.

    Please explain to me.

    1. You need a contactor for controls. Check the input voltage of your contactor coils and ensures it’s the same with the voltage that’s powering it.

  5. A three phase motor had Star Delta written on the name plate but could not work in 2 speeds (star-delta). It was correctly connected.
    What could be the problem?

  6. Kindly email me the diagrams for star deltor and direct online for a 3speed 1directon 3ph motor, have two of them in a Bow Cutter. One contactor burnt for high speed and a replced contactor does not engange, originally the coils re fed with a nutural and the one i replaced is only working with a phase. please help how to go about this

  7. i want to know the working principle of power system and is their a right diagram spacialy star connection k2 with low k1 and is their wanted overload after motor?

  8. Here use 3 contact
    Why here low speed during time 2 contact energy (k1,k2)and high speed running time(k2)
    Only one
    And why we use low speed time star winding
    High speed time with out Star winding
    Say something about it as soon as possible
