Low voltage is up to 1000 v, medium voltage is from 1000 v to 35 kv, and high voltage is over 35 kv. Higher voltages mean lower currents, and lower currents mean less heat generated in the power line due to resistance. Sometimes you apparently need to rewire a 3 phase motor for low voltage 230v as opposed to 460v in order to connect the motor to a vfd. Wire the motor for the appropriate voltage to which you are connecting the motor. If you double the voltage and keep current the same, you can use the same wire to drive a load twice as big. Medium voltage ac drive suppliers always require an isolation transformer to protect the ac motor from high voltage transients. The baldor is setup to the high voltage out of box. An assumption people often make is that since low voltage increases the amperage draw on motors, then high voltage must reduce the amperage draw and heating of the motor. Low voltage vs high voltage motor wiring. Home » unlabelled » low voltage vs high voltage wiring a motor / left unchecked, voltage drop causes countless unsolved electrical mysteries, especially when it infects the ground side of a circuit. I have always used 440 and am wired for the high side but have recently aquired a smaller generator wired low i accidentally ran a motor configured high on low voltage and it worked fine. The nameplate will specify the motor voltages and may give specific wiring information. Examine the motor nameplate for wiring information.
A low voltage supply is more harmful than high voltage because it decreases the magnetic flux in the core iron. It is often more efficient to use higher voltage and lower current. Is there a benefit to either high or low if the vfd will operate it? High voltage on a motor tends to push the magnetic portion of the motor into saturation. The cost of a 4160 vac to 480 vac step down input isolation transformer is no more expensive than the cost of a 4160 vac to 4160 vac input isolation transformer.

It sometimes becomes necessary to test or confirm the configuration of a motor before final connection. I have seen the results of someone not following this simple instruction on a 400/690 volt motor. Higher voltages mean lower currents, and lower currents mean less heat generated in the power line due to resistance. One will be for low voltage and another for high voltage connections. Every motor i've ever seen has labeled the higher numerical figure as high voltage on the connection diagram.
It is often more efficient to use higher voltage and lower current.

Low voltage is up to 1000 v, medium voltage is from 1000 v to 35 kv, and high voltage is over 35 kv. The cost of a 4160 vac to 480 vac step down input isolation transformer is no more expensive than the cost of a 4160 vac to 4160 vac input isolation transformer. A low voltage supply is more harmful than high voltage because it decreases the magnetic flux in the core iron. In electrical engineering, low voltage is a relative term, the definition varying by context. Depending on the voltage you have measured in the first step, you should select the appropriate diagram. Identifying wye or delta with an ohmmeter. 208 is the voltage your wiring the motor to. Not using the core iron optimally causes efficiency and torque to fall as the motor's internal temperature begins to rise. Since the motor is a 230/460, and you have a 208v supply, you would wire it low voltage. And the low voltage connection is for 230v service. 208 is the voltage your wiring the motor to.so if higher voltage transistor have to give out the same ammount of current to give out the same power to the speaker, whats the adavantage of having a high voltage supply for the outputs. To protect, high voltage motor we uses motor protection relay. Sometimes you apparently need to rewire a 3 phase motor for low voltage 230v as opposed to 460v in order to connect the motor to a vfd.
High voltages require specialized switching and distribution panels.
