How to calculate the motor winding resistance ?..

Answer / bharat

In electric motor there are three windings.
U, V ,W ,respectively, so measuring of resistance of motor first. switch off electriacal system.
then take e Multimeter and set on Resistance / O'hm. then both cord of multimeter put on U-V winding.. and see the multimeter reading and note..

How to calculate the motor winding resistance ?..

Answer / sundar

I know the motor power and motor winding gone then how i
know this motor is good or bad. so i want calculat motor
resistance from motor power.

Is This Answer Correct ?    5 Yes 7 No

How to calculate the motor winding resistance ?..

Answer / bhuvan sharma

firstly separate the both connection means main and aux winding then find out the both windings resistance by multimeter .

Is This Answer Correct ?    1 Yes 3 No

How to calculate the motor winding resistance ?..

Answer / sarath nair

Disconnect motor terminals and check the winding resistance
with a multimeter at the two ends of each coil(U-U1,V-V1,W-
W1) and find the minimum acceptable value by using the
formula (Rated voltage (V)/1000+1)

Is This Answer Correct ?    1 Yes 3 No

How to calculate the motor winding resistance ?..

Answer / d ramesh

disconnect the motor terminals, connect the multimeter
between r-phase two terminals,then multi meter reads the
resistance of the motor winding in r-pahse, similarly for
y&b-phases.

Is This Answer Correct ?    8 Yes 12 No

How to calculate the motor winding resistance ?..

Answer / r.p.samy, national switchgears

Pl check how the winding of motor is connected . Whether it
is Star or delta we have to use 4 probe Ohmmeter ,
preferably injecting a current of 10A . The resistance can
be accurately measured

Is This Answer Correct ?    3 Yes 9 No

How to calculate the motor winding resistance ?..

Answer / daher

bring motor, open cover,disconnect motor winding,make each
phase separetly,use muttimeter,select ohm reading
(resistance in ohm),put the tester probs on 1 phase
terminal,look at tester pointer how much the
reading ,reccort it .

Is This Answer Correct ?    19 Yes 30 No

How to calculate the motor winding resistance ?..

Answer / shashikant

there is One meter Called Motor winding resistance meter
(Ohmmeter). it does have four termainal namely 2 V(+ and -)
and 2 I(+and-), all the four terminal are connected to the
winding of motor to which we want to calculate the
resistance,namely Voltage leads are near the studs of the
winding and current leads are connetcted at the edge of the
studs so that while applying the voltage the resistance of
the winding can be calculated rather the the resistance of
the outer studs.This methos is allowed for both D and y
connection.........
Namaskar
