Can a 230-460 volt motor be connected to a 120-208 volt circuit?

Yes it will run. That said you will be shortening the life of the motor due to the excessive heat generated at the higher voltage. The insulation of the motor winding is related to the voltage that is applied to the motor. With excessive heat comes insulation breakdown. Once the insulation breaks down, the winding will start to short circuit. With a short circuit on the motor winding copper wire is lost. Think of a welder when an arc is struck. Once this happens to a motor it becomes non operational and a rewind is the only way that the motor is going to become operational again.
Install a Buck & Boost transformer rate for the HP of the motor that will Buck the supply voltage for the motor down to 230 volts. This is the recommended way and the only way it should be done. Any good commercial electrical supply house can help you properly size the transformer that you will need.

What happens when a curcuit is closed?
To close a circuit in electrical terminology is to close any open devices that are in series with a connected load. Once this happens the current will flow through the load and the load is then termed as energised. In the case of a motor circuit the motor will operate. In the case of a lighting circuit the lamps in the circuit will energise and light the area in which they are installed.
What will be the effect if the d.c motor is directly connected across the supply without starter?
At zero rpm a dc motor draws a current that could be enough to blow the circuit breaker. In that case it is normal to place a resistor in series to limit the current to slightly below the circuit-breaker setting. The resistor is switched out after the motor runs up.
How can a dlta connected motor be converted in star?
If the motor terminal has six terminals in the terminal box, then it can be connected either in delta or star. If there are only 3 terminal wires then the motor can not be connected in star.(it means that the motor is designed to be connected in delta only)
If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?
In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.
How do you identify a burnt out motor without meggering?
If the motor is still connected to its electrical supply and it is safe to do so switch it on and check for an odour of burning insulation and or the presence of smoke. A burnt out winding can cause a motor to run very slowly and make a unusual humming noise, if this cannot be achieved safely then make sure the motor main switch is isolated and sniff around any ventilated area of the motor to check for the smell of burning insulation. If you have a circuit tester that will check for continuity then use this after firstly completely isolating the motor from its electrical supply and disconnecting the wiring to the input terminals. You may see and open circuit reading between the live and neutral terminals or a short circuit between one or the other terminal when the tester is connected between the terminals and the metal case of the motor, remember that a circuit tester will read resistance so try the test on the appropriate setting, example; RX10K

What does a Y mean on a printed circuit board?
it means that it's star connected on the motor part
What is a motor in a circuit?
A motor in a circuit is classed as the circuit's load.
Can the power to your whirlpool be on the same 20 amp circuit as the bathroom lights and outlets?
No, the whirlpool has a motor load connected to it and should be connected to a dedicated ground fault breaker.

What are examples of a load in a circuit?
Any specific device that draws a current which is connected within the circuit is an example of a circuit load. That may be a resistance and a loudspeaker LED computer and induction motor or whatever which can withdraw the energy from the output.
Why is it that all electrical motor circuits are equipped with both a motor control circuit and a control circuit?
First you need to have hands on experience on industrial electrical components to get great idea. Various components in motor circuits are contactors, breakers etc.. In control circuits we've the coils of contactors breakers, relays, sensors etc.. Take a contactor, it has 6 terminals called main contacts, 3 connected to source 3 connected to motor nd in these 2 sets one is stationary nd other is movable. Initially they're isolated nd when in contact motor is connected to the source. Here motor circuit completes. These pair of main contacts can be get in contact mechanically or electrically. But for speed, accurate nd smooth operation an electromagnetic coil (pick up coil) is arranged in the contactor such than when electric current passes throug this coil it'l attract the movable pair of main contacts to get in contact with the other pair to complete the motoring circuit. Relays sensors protection units can be connected with the pick up coil (control circuit) to ensure customized control on motor.
What will cause electric motor to shock you when you touch it?
The motor winding has gone to ground internally. The ability of the motor to shock you is caused by the ground wire missing or not connected. It is this ground wire that trips the breaker in short circuit conditions and disconnects the motor from the distribution system.
What will be the effect if the d.c motor is directly connected across the supply without starter?
At zero rpm a dc motor draws a current that could be enough to blow the circuit breaker. In that case it is normal to place a resistor in series to limit the current to slightly below the circuit-breaker setting. The resistor is switched out after the motor runs up.
Why you are using star connected induction motor and delta connected induction motor?

How do you ground a motor?
A motor is grounded with a lug in the motor's junction box. The ground wire in the supply cable is connected to this point. This lug grounds the whole motor frame so if a fault to ground occurs, the fault current will return to the distribution panel where the motor's supply breaker will trip and open the circuit.
