Low voltage motor hook up

Do motors need to be wired for low or high voltage?

While many have eluded to it, just to be perfectly clear: wiring the motor for low or high voltage would depend on what voltage is available to supply the motor. Delta or wye is not relevant really. 120 volt motors do.

What happens when voltage is low on a motor?

To drive a fixed mechanical load connected to the shaft, a motor must draw a fixed amount of power from the line. The amount of power the motor draws has a rough correlation to the voltage 2current (amps). Thus, when voltage gets low, the current must increase to provide the same amount of power.

Is a 230V motor high or low voltage?

Since the motor is a 230/460, and you have a 208V supply, you would wire it low voltage. You would wire it high voltage if you were supplying 460V. And note that a lot of motors have a low voltage range of 208-230V.

Is 208 volts too low for an electric motor?

In the US the most common voltage level at the meter is 240. If the low voltage you are asking about is above 208 volts your motor should be OK. Yes it will draw more amperage at 208 volts than 240 but the motor is designed to not overheat at this low voltage. Why do electric motors take a large current on low voltage?

What voltage do you wire your motor to?

And note that a lot of motors have a low voltage range of 208-230V. I work for a service shop. No complaints, love what I do. Right. And whether a 9 lead motor is wired wye or delta at the factory has no effect on whether your supply is wye delta. Since the motor is a 230/460, and you have a 208V supply, you would wire it low voltage.

Can I connect a high voltage motor to a low voltage source?

However, if a motor is wired for low voltage, do not EVER connect it to a high voltage source (either Wye or Delta) as it will overheat. On the other hand, if a motor is wired for high voltage, it will fail to operate if connected to a low voltage source.

What happens if a motor is wired for high voltage?

On the other hand, if a motor is wired for high voltage, it will fail to operate if connected to a low voltage source. For those standard nine-wire motors that have internal Wye connections from the factory, a mental image of the winding arrangement may provide some insight for the reason behind making certain connections.

What type of connectors do I need for my electric motor?

The type of connectors will depend on the manufacturer and size of the motor. Locate the wiring diagram for your motor on the faceplate or inside of the cover you have removed. Typically, you will have two distinct diagrams. One will be for low voltage and another for high voltage connections.

What voltage is 208 volts?

Now to get back to our question. 208 volts is Line-to-Line Voltage. This three Phase voltage is frequently used in small businesses.

Why am I not getting 208 when wiring the motor?

Your not Getting 208 by wiring the motor. 208 is the voltage your wiring the motor to. A motor data plate will list the rated voltages for the motor and show the diagram of how to connect it to the system. Whether a motor is wired Wye or Delta has no bearing on the line voltage (unless designed as such).

Can a 230 volt motor be made into a 208 volt motor?

This approach is that by using a somewhat more conservative design on the 230 volt motors it is possible to create a 3 phase, tri-voltage motor with voltage ratings of 208-230/460. With this approach the 230 volt winding (and connection diagram) is used on the 208 volt power system.

Do motors need to be wired for low or high voltage?

While many have eluded to it, just to be perfectly clear: wiring the motor for low or high voltage would depend on what voltage is available to supply the motor. Delta or wye is not relevant really. 120 volt motors do.
