Could the slow spin...
...be down to the induction motor's pulley sticking?
Some european induction motor machines had pulleys on the motor shaft, that opened and closed depending upon the speed of the motor. The motor pulley(s) would move together by centrifugal effect, causing the belt to ride up onto a wider diameter shaft, altering the pulley ratio and thus giving a faster spin speed.
