Answer Posted / avd
Cold start : Starting the motor when it is cold. Means when
motor stoped and starts after long delay, considered as
cold start. Techanically if motor thermal containt is less
than 50%, it is considered cold.
Hot start : When motor is hot and you give start. Means
stoping the motor and immediately restarting is hot
start.Techanically if the motor thermal containt is more
than 50% and a start is given to motor, it is a hot start.
Effect : Any start of motor will result in increase of
thermal containt. If motor is hot (hot start given) than
motor thermal containt further increase hence there will be
detorioration in the insulation and thus life of motor.
