Re: Sluggish synchronous motor
"Hypoid" is the name of a tooth shape used in right-angle gearing, and hypoid oils are the specially formulated lubricants for these tooth-shapes where the pressures are significantly greater than in ordinary parallel gearing, whether straight-cut or helical. Some manufacturers specified hypoid in car gearboxes to simplify servicing, but the drive for greater economy stopped that.
Hypoid oils impose a lot of drag, Ricard, though not as much as grease, so are you sure it's Hypoid 80 and not just a plain 80 grade?. I'm very surprised at them being needed in a tape recorder. They are also a bit smelly.
I'm glad to see this come to a successful conclusion, it had been mystifying me.
£100 for a motor is close enough to the sort of silliness going around that it wasn't certain that it was a wind-up, there was just enough doubt.
Cheers
David
