Can I Run a 380v Motor on 460v

Running at lower voltage will reduce starting current and torque but lets say there is still plenty. As countryman said you motor will run faster no matter what but you dont necessarily need to buy a.

Original motor with 60Hz V 480v.

. Lets assume its a 3 phase induction motor and a reasonable size - say 100kw or more. Yes As long as the vf ratio is same 46060 76 and 3806076. Motor torque varies by the square of the applied voltage at a fixed frequency so your output torque will be 82 x 82 or 67 of the normal available torque.

It can be used with reducing output power. If thats no big deal Id use it since I already have it and when it fries replace it with a 575V motor. Can you run a 460v 60hz motor to a 400v supply.

The biggest issue will likely come into play if the load is a centrifugal pump. Yes can run but motor only delivers 90rated power because vf less by 10 Can a 440 - 480V 60Hz motor run in a site with 380V 60Hz supply If No how. Then if we reduce that by the above square factor you.

In any case the motor will run faster. Now you have to watch this as it needs to get upto speed before it. The inductive reactance is higher at 60Hz but the applied voltage is.

In both cases the VHz ratio is 76 VHz. Be used in 50Hz power supply with voltage reduction V 400v. GoHz frequency converter accepts three phase 380v400v415v440v460v480v 50Hz 60Hz input the output is vary from 0-520v 40-120Hz also can be customized for input output for specific applications.

Be used in 50Hz 380v power supply directly. In the USA standard is 480V distribution and 460V utilization voltage If your supply is actually 460V then the ratio is 46060 767 close enough to the original 76 as to make no difference. Speak to the maker of your motors first of all.

Now run at 60HZ 380Volt brazil volt drop from 480 Volt to 380 Volt at the same 60 HZ. But of course you have to ask the minimum speed this motorcould run since it will cause overheating of winding when usingVFD. If for example the motor is 460 Volts and 60 HZ it wont do well at 380 Volts and 60 HZ but itll do fine at 50 HZ.

The motor would be able to produce rated torque at both frequencies only apply if the VHz ratio is constant meaning that at 50 Hz the supply voltage would need to be 380V and at 60 Hz the supply voltage would need to be 460V. It can not be used for a long time or even can not be used. You can go to the Contact page to get a price.

In a 380V motor they will use the same insulation as a 460V motor so its not a big deal but most 460V motors are not built to be connected to anything higher. If it is a 4-pole motor with a nominal speed just under 1500 RPM the new nominal speed will be just under 1800 RPM. Your motor is designed around 380V 50Hz and 3805076VHz.

Why the difference is 20. Dan with 380 Vac output from the VFD and the motor looking for 460 Vac you will be able to supply the motor with the correct VHz ratio up to about 80 of its normal speed range 380460 0826. The main cause to motor heat temperature rise is a load current.

Motors for use in the US are designed around our utility voltage of 480V 60Hz so 4606076VHz. Im not concerned really with operating a 380V50Hz motor on 460V60Hz Im concerned about the torque the load requires at the higher speed. As to running currents for a motor running on 480V vs 460V when running at the lower voltage the motor will draw.

This motor is design for run at 480V60HZ and also at 380V50HZ. In other words it should run fine up to 80 speed but above that the VHz ratio will start to decrease because the VFD cant put out any more voltage to maintain the. From motor output power formula PSQRT3UIcosFETA it is clear that the current will remain about the same when we will use 400V 50Hz motor power and 460V 60Hz 50Hz20 motor power.

You might need to limit the max HZ in the VFD program. So assuming it is a 4 pole 1800PRM motor and HP tq x RPM5250 then design torque at 460V 5250 x 320 1800 93333 ft. If it were me Id evaluate this based on the cost of unexpected down time.

A three phase 460V motor operating at 60 Hertz has the same VHz ratio as a 380V motor operating at 50 Hertz - approximately 76VHz. The output power is 83 of the original power. Chances are that the motors are actually suitable for both voltages and the maker can issue you with new data plates to cover the revised voltage.

The data can be found on motor nameplate.
