I assume your question relates to the need for a disconnect switch. To meet code you need a disconnect switch in the proximity of the motor so that should the need arise the motor can be disconnected for safe maintenance or in an emergency. The motor will work directly connected, but you will create a safety issue.
What else can I help you with?
What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
What is the minimum voltage a 115vac 400hz 3 phase motor will run?
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
How do i switch a 3 phase motor from low to high voltage?
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
Will you produce a 3 phase voltage if you rotate a 3 phase motor physically at its specified rpm?
yes
Vlotage on motor name plate is line or phase voltage?
The voltage tag on a motor says 120 or 220 volt and some motors have jumpers to wire it for either one. That is the supply line voltage. The motor knows how to use that. If the plate says three phase is required then consult your electic supply Company for a three phase supply line.
Does the speed of a split phase motor changes appreciably with a change in the applied voltage?
The speed of a split-phase motor is directly proportional to the frequency of the power supply, not the voltage. As long as the frequency remains constant, the speed of the motor will remain relatively stable regardless of minor fluctuations in voltage within normal operating limits.
What voltage is found on a single phase motor?
Ac voltage
What is the phase voltage inside a motor if one phase is lost and what is the voltage between the other two phases?
The phase voltage is usually constant and determined by the supply voltage.
What is the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?
If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.
Can you connect 240 3 ph motor to 480 3 ph by dropping a leg?
No, you cannot connect a 240V 3-phase motor to a 480V supply by dropping a leg. The motor is designed to operate at a specific voltage, and changing the voltage in that manner can damage the motor and pose a safety hazard. It is recommended to use a transformer to step down the voltage to match the motor's rating.
What is the minimum voltage a 115vac 400hz 3 phase motor will run?
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
Can i run single phase dc motor from 3phase bldc controller. i m using single phase motor in motorcycle and controller from other electric vehicle. if yes please tell me how to connect it?
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
How to connect 3 phase power factor correction capacitor?
how to connect power capacitor with 3 phase motor
Can you replace a 480-240V 3-phase motor with a single phase motor as a temporary replacement or will it burn it out?
Yes, you can, and it won't burn out IF>>> the horsepower rating is the SAME. Pay attention to wiring and motor rotation. Also check the voltage: the motor voltage must be the same as the voltage between two hots of your 3 phase system. You will only use two hots as this is a single phase motor.
How do you determine a 3 phase motor and each winding?
To see if the motor is three phase or single phase look at the motor's nameplate. There it will tell you what the voltage needs to be and what system phase the motor needs to be connected to operate properly.
Can a 415volt 3phase motor run on 525 volt 3 phase?
It is not advisable to run lower voltage motor on a higher voltage.
How do i switch a 3 phase motor from low to high voltage?
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
