Induction motors
Yes, they had induction motors, and just varied the amount of poles I think according to the spin. You either got a 400/800 or a 500/1000, but it was a `true' speed, as opposed to other machines around at the time like a Candy which used centrifugal clutch. Those Candys were fascinating to watch on spin - the machine would be spinning at 400 and making a cetain `tone', then sudenly you'd hear something mechanical going on, the machine would shift up to 800 but the motor would still be making the exact same tone. Fascinating to watch from the rear how it was done. (??)
Anyone own one of these `brown fascia' Candys? They were not bad machines, my landlord in London still had loads on the go in his rental properties back in 2001.
