I was scavenging my pile of parts clocks for a specific type of flap, which someone was after and eventually ended up finding them in a Saba radio-alarm-flipclock. Since I had the clock open anyways, I figured I might as well see what type of motor is in there, what is the condition and whether it made sense to remove it, label and put it in my box of motors. Low and behold my discovery that in spite of being a 220v radio-alarmclock, the motor driving the (Copal) clockwork is 100v... and 50hz (at least that makes sense).
What could be the idea behind this? Would the radio part be driven by 100v through a transformer and was it cheaper to make it so that the clockwork is also driven from that same point?
Perhaps we will never know, but it certainly surprised me!
