The megger leads are connected in the following manner. Black lead to motor ground terminal or motor frame. The other lead to one of the phase wires. Meg that coil to ground and note the reading. Do the same with the other two motor leads and note the readings. Look at all of the three reading that you have taken. Engineers like the reading to be above 5 meg. Preferred readings about 2 meg. Motor needs looking after below 1 meg.
What else can I help you with?
What readings are normal when testing a 3 phase motor with a mega-ohm meter?
1.46 meg ohm
Is 3 phase motor run on 1 phase supply?
No. That would be a single phase motor.
How do you turn a 3 phase motor in to a generator?
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
Is a 3 phase motor a Synchronous motor?
A synchronous motor can be a type of 3-Phase AC motor, or not.A synchronous motor is defined by the period of the rotor being synchronized with the frequency of the stator windings' current. The stator windings might be 3-Phase or not (2-Phase would work).Also synchronous motors are not the only type of 3-Phase AC motors. An induction motor could also be 3-Phase AC and has a few advantages and disadvantages over a synchronous motor.
How do you convert or rewire a 20HP 3 phase motor to single phase motor?
The winding design of the motor will not economically allow this to work. You would have to drive a 3 phase generator to supply it.
What are the advantages of three phase motor over the single phase motor?
A 3-phase motor produces a steady torque that does not pulsate. A 3-phase motor starts turning in the right direction when switched on without the need for a separate starting winding.
What size motor do you need to run a compressor 2 stage 80 gallon tank i have a 3 phase on it and want to change motor?
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
What 3 phase conction of eletical diagram?
what is 3 phase eletical conction digram of 3 phase motor
Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
When changing phase rotation of a 3 phase motor is this done at the switchboard?
The phase rotation of motor should be always done from motor side i.e The motor terminal box.
How may wire on a 3 phase motor?
3
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.
