An inductor can be used, in principle, but it has to be the right inductance, it will waste more power than a capacitor, and the motor would rotate the opposite way.
With the starting winding disconneted the motor will start up in whichever direction it is spun. To make the starting winding operate the other way, it needs an inductor in series insead of a capacitor. Details depend on the motor, but the reactance of the inductor should match that of the capacitor.
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
No. You won't be able to start the motor without the capacitor.
Depending on voltage and amperage needed to run the motor,say,3volts.If you use a 3+volt capacitor what will happen is that the motor will turn once(not rev/min) and stop when the capacitor is completely drained which would occur in about half a second or less. Contributed writer:Dennis Wachira.
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
Function of Capacitor in Air Conditioner:Compressor Motor Capacitor: This air conditioning capacitor usually consists of two capacitors that are combined. This vital capacitor gets the motor running in the air conditioning unit.Start Capacitor: This capacitor provides auxiliary support and that is not a standard on every air conditioning unit. It can give the motor a boost to get it started.Indoor Blower Motor Capacitor: This capacitor is self-explanatory. It is responsible for starting the indoor-blower-motor and keeping it running efficiently.Outdoor Fan Motor Capacitor: The name says it all for this capacitor. It starts the outdoor fan and keeps the air flowing through the coils that run on the outside of an air conditioner.
If a capacitor is directly connected across a motor then the capacitance of the capacitor will be calculated as under.Q = 0.9 * Sqrt (3) * V * I0.Here "V" = Supply voltage & I0 = No Load Current of Motor.AnswerThere is no need to connect capacitors across a three-phase motor.
cheap,quiet,long lifetime for motor
The value of the capacitor for a 1hp AC motor depends on the specific motor design and manufacturer guidelines. It is important to consult the motor's documentation or contact the manufacturer to determine the correct capacitor value for proper motor operation.
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.
