Answer / shahulsnfa

yes the motor will run.. but u will not get the rated
torque of the motor since voltage is directly proprtional
to torque.

Answer / kishor mahale

yes motor will run, but motor will not get rated torque and
speeds. because torque is directly proportional to current,
and speed and torque are inversely proportional.

Will a 230VAC motor run OK at 208VAC...

Answer / jignesh kadia

yes, motor will run with lesser torque & speed..but after
some time it's get overheated because of they run under
exited condition.the emf not much produce to rotor cause
rotate at rated speed so that humming produce in it. the
losses are produce in motor and it's get overheated.. and
motor will burn out..

Is This Answer Correct ?    1 Yes 1 No

Will a 230VAC motor run OK at 208VAC...

Answer / suhas

yes, it will run.... since voltage is lower, to maintain
the output power to its rated capacity it draws more
current...due to which the windings get heated and burnout
will take place....

Answer / er. dattesh shah

YES MOTOR WILL RUN WITH LESSER SPEED THEN OTS RATED SPEED.

Is This Answer Correct ?    0 Yes 2 No

Will a 230VAC motor run OK at 208VAC...

Answer / suresh kumar

Motor will run with lesser speed and torque. But if the
load is same as in the case of 230VAC, current will be more
and motor may burn.
