nameplate speed on induction motor??
(OP)
hi all
i want to know the nameplate speed on induction motor is full load speed or no load speed?
i know when T-s charactristic induction motor and load charactristic cross together we have definite slip and load speed,but is it equal nameplate speed?

if we load the motor(full load), we reach to another speed !! am i correct?
what is the diffrence between two speed or which of them ic nameplate speed?
RE: nameplate speed on induction motor??
the fuzzy part is the on the definition of load.. it's given in watts not torque. you read the name plate speed, divided by rpm-> rad/s to get the rated torque.

Full load means the condition at which the motor load ( brake horsepower) is equal to the nameplate HP.

At less than full load, the speed will rise up toward sync speed until, at no load, it will be within about 1rpm of sync speed (due to windage losses, bearing drag, and seal drag).
In fact, assuming the supply voltage is correct, the shaft slip is probably the easiest and most reliable indicator of motor load available for field trades people.
