I imagine that the motors in modern(ish) record players are not strong enough to pull a steel needle and heavy soundbox.
Does anyone know if new 'heavy duty' motors are still manufactured by anyone which are suitable for connecting to a gramophone turntable etc ?
Are electric motors suitable for gramophones still manufactured ?

Re: Are electric motors suitable for gramophones still manufactured ?
I'm guessing you can probably find a nice vintage one for not too much money. I have some older heavy duty turntables that were used for radio stations, that I have considered adapting to acoustic arms and horns. by the time you fuss around adapting of new manufacture, you can probably find a good older machine that has a relatively powerful motor.
A machine such as a technics direct drive turntable can be had with a pretty powerful motor that stay dead on with the speed control, even with varying loads from the tone arm. but it's not going to look the part.

I have a huge 1931 Grigsby-Grunow, out of a Majestic 100, out in the shed.
If you wanted to build a gramophone I would hunt up something of that type.

Re: Are electric motors suitable for gramophones still manufactured ?
There are certainly geared electric motors which run in a suitable speed range and would be powerful enough. I built a rather crude proof of concept in the following video, but I think it shows the possibilitiespoodling around wrote: ↑Sun Jul 24, 2022 5:03 am Does anyone know if new 'heavy duty' motors are still manufactured by anyone which are suitable for connecting to a gramophone turntable etc ?

Very interesting about your ex-radio station heavy-duty turntables.anchorman wrote: ↑Wed Jul 27, 2022 2:03 pm I'm guessing you can probably find a nice vintage one for not too much money.

I do have an old electric Indian teak gramophone but the motor had been professionally reconditioned when I bought it so I feel 'happier' about using it.
I think a new motor would be something I would prefer for an art-deco floor standing gramophone I have.
Thanks - interesting stuff.

I haven't heard of that model before so I will go some internet searching.

Thanks
I have built other electrically powered acoustic gramophones. I think the one in the following video is one of my favourites:
