question about motor controller amp rating

[robb]

i have a sewing machine motor controler (wired in series with motor) that
uses a
"carbon pile element" where pressure on the pile causes decrease resistance
and more current to flow and at some pressure point a short by passes the
carbon pile

controler is rated at 95-145 volts and 0.7 amps

now someone has claimed no troubles using the controller with 120v - 1 amp
motor

is this true ? why or why not

ithought the motor would potentially try to draw more current than the
controller was rated for and of course overheat etc

any help greatly appreciated

some designers as a rule allow for some design overstress. i do it for sure so 36% is good but not neccessary he or she might use it the question remaining is for how long Heat destroy fevices so for intermittent use it may last forever.
