How can you tell if your motor centrifugal switch is bad?
I cannot be 100% certain that the centrifugal switch on my table-saw motor is bad, but here are some symptoms that I recently experienced: 1) The motor starts fine, but the motor-start capacitor begins smoking (bad sign) while the motor is running. I think this means the switch is sticking closed in this case. 2) Other times, the motor does not want to start at all. If I slacken the drive belt, the motor starts spinning. When it gets up to speed, I can tighten the belt and go ahead and use the saw. In this case, I think the switch is sticking open. I first experienced symptom #1, which led me to believe I had a bad capacitor. I replaced it, but after a few uses, the new capacitor also smoked. Then I noticed symptom #2. After doing a little web snooping, I have nearly concluded that the problem is the centrifugal switch. Just not sure yet how to get to it or find a replacement. . . Bucky K in Ohio
Is a electric motor a simple machine?
yes
In what two ways can the rotation of a shunt connected dc motor be reversed?
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
Can you mount an electric dc motor in a vertical position?
Yes.
Efficiency of a motor?
ratio of energy output to energy input.
Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
How many microfarad of running capacitor is best for a 1.5 hp 220volt motor?
There are many different 'run' capacitors on motors. It depends on the motor make and use. You need to consult your manual or local electric motor shop.See related links below for good information on how capacitors effect motor starting.

What is the common application for capacitors in electric motors?
There are 2 types of capacitor including starting capacitor and running capacitor running capacitor are used to improve the power factor of motor. starting capacitor used in split phase induction motor . starting capacitor may isolate from motor,s starting winding through of centrifugal switch after getting motor 90% of it,s rated speed.
Which of the following Dc motor is suitable for high starting torque?
capacitor start motor
Why capacitor is used in ceiling fan?
Capacitor helps a motor generate a starting torque. once the torque is produced and motor rotates capacitor acts as a current path. technically capacitor creates a phase difference.

Can a larger capacitor be used in an air conditioner?
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.
You switched leads on your 3phase motor and it did not reverse?
Then it is not a three phase motor.
What is a split phase motor with relay and capacitor called?
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
What are the capacitor effects on a single phase induction motor?
As anything to do with timing values for an electronic system of controlling a motor. Based on the question, the simple answer is that the capacitor causes a 90 degree lead which allows the motor to have a magnetic shift which causes the motor to start rotation.
