I'm restoring a Kriesler Carrygram from the 60s. It's a very compact battery-operated portable.

I'd like to replace the original motor and drive - they were never any good even when new, with awful wow and flutter.

So I was thinking of grafting in a more modern DD motor, retaining the turntable. The mechanical speed change could be replaced with a rotary switch.

Anyone got a battered DD turntable lurking somewhere they'd be prepared to sell?

If you can get one small enough a pulse width motor like in electric drills may be more practical as you may be able to direct drive the platter using its modified modulator.?

There's a guy in Canada who pulls DD motors and driver boards out of old turntables and sells them on Ebay.

I'm not in a hurry, I might go down this route if nothing else turns up.

Marcc, there's also the very interesting (but much too large) one in Fisher and Paykel washing machines.

We have one of these machines that has given faultless service for nearly 40 years. No fluid seals, no gearboxes, no belts. No problems!

Fisher and Paykel direct drive motors are sought after by those wanting to make their own hydro or wind generators.

I'm waiting years now for my Simpson washing machine to die so I can play with the DD motor but it just keeps grunting away.
Probably out live me the way it's going.

Motors that run from VSDs, including modern washing machines, generally do not expire. It is the dashboard where the issues ussually come about and it is not cheap to replace parts in them.

My Simpson 9.5kg machine is about 12 years old, purchased at Masters (remember them?) and is still going strong.

I reckon my Simpson is the same age. When I bought it I insisted on a machine with knobs, not touch screen display and pretty lights.

The salesperson spotted me as a dinosaur of course, but obligingly found one with a rotary knob on a panel with several push buttons. The best there in my opinion, the worst in his.
Hell, some of the damn things had a USB port. "What the hell for?" I asked. "so your computer can start your washing for you while you are at work---". Yes, naturally, I thought to myself, another less bit of excercise for our over-fed under-worked bodies.

The lid sensor failed about two years ago, I fixed it and cleaned out the dust & cobwebs etc. and it hasn't missed a beat since.

No computerised stuff here. Years ago the old Hoover washer died, so bought another one, same model. Have replaced the cold water solenoid. Everything else just hums along.

My experience with appliances using motor driven sequencing switches vs a microcontroller has been the complete opposite. The microcontroller-based products win hands down in reliability.

We had a dishwasher that went through 3 mechanical motor-switch assemblies.
