If the stylus side has a power supply, that needs to be dealt with as well.
Also, can you post the motor part number or description?
It is most likely a ready bought out item.
For example, Denso plugs were 3x more expensive at Honda dealers than at Toyota dealers in the UAE...it may be the same if you contact the agent, better to obtain the motor outside that channel.
The pulley will still be used on a stepped down supply, I think, and the synchronous speed will be different at 50Hz, same pulley, and the motor may not like being fed 50 Hz, it has something to do with the helix angle on the rotor, not something you can correct.
Though it is not very important in a toy motor like that...anything in fractional HP is a toy for me.
The decision will be made on ease of doing it, and the cost.
I see no reason to spend $350 or more when I can get a good table locally for less than that.

As you can see from the above post this is not a cheap TT and well worth getting it working properly. I'd be incredibly surprised if the motor differs between the 50 and 60 Hz versions so the most cost effective solution is to obtain the correct pulley from either Marantz or, more likely Clearaudio.
The minor question of 120 V and 220 V is also to be borne in mind.
It is unlikely that the same motor will work on different voltages with the same winding, unless a switch or wire link of some sort is provided for using the entire coil at 220 and half coil at 120 (or the other way round).
Looks like some Thorens models, those motors might fit, check the belt size.

If we assume the correct pulley can be sourced ( I know what assume can be broken down to 🙂 ) then obtaining
a step down transformer is trivial, Amazon sell a selection for around £25.
Given the price of the unit it's reasonable to assume the motor is of decent quality and should not need to be replaced.

Some motors will work, some may not, Marantz was a finicky make.
Let us hope for the best, the motor will draw at most 50 mA AC, so the transformer should be inexpensive, the proper one should be a magnetic type, not the electronic type.
I agree, inexpensive item.

Hi, Knowing the cost of manufacturing T/T's I would expect the motor to cost about $10. Normally it is well worth replacing the supplied motor. A decent motor will cost around $100 to $300 & it is a known upgrade path.

A replacement motor is no advantage whatsoever unless we also have the corresponding pulley and belt.
All that's needed is a pulley from a 50 Hz
Clearaudio Emotion SE and a 230->120V
Transformer.
I don't think this thread will go anywhere until/unless the OP moves things forward.

What is the motor shaft size?
Maybe 8 mm, so a 8 to 40-odd mm pulley could be a ready item at hardware stores and model suppliers...

Did a search for 8 mm dia 44 mm pulley, and this turned up....!

That is versatile, may not be useful, but gives a reasonable idea of what is available.
Small Aluminum pulleys are in the $2 range, not at all expensive, from other sellers.
No ties to any seller.
Now the OP has to reply, or I am off this thread.

If That is the case, then the OP should go to a machine shop & have one made, simple. What i was doing was suggesting a solve & upgrade as these cheap 60/50 hz motors often hold a T/T's performance back,
That's why Linn has finally gone DC.

Still awaiting a response from the OP, but in the meantime suggesting a DC upgrade like Linn has done with the Radikal is perhaps a step too far as that one comes in at about £4500.
Origin Live has a much more cost effective one, but the one listed at over £1000 still uses a cheap dc motor that has a comparatively limited life expectancy, apparently owing to bearings that can't handle the expected side thrust when run at lower speeds such as those typically found in turntables
As I mentioned above, DC motor driven TTs
tend to have quite poor longer term drift unless a feedback circuit is used, which adds another level of complexity.

Simpler to use a higher rpm motor, from a good maker, the bearings will be better quality, the higher speed will reduce vibration from the bearings, and maybe a tacho-generator can be attached as a feedback source.
Then you can use a micro controller like the Raspberry Pi or Arduino to actually control the speed.
As an aside, the digital files comprising OP record collection may be cheaper to buy than all this effort, safer, less hassle.
But the feel of a record, the musty smell of sleeves, and so on...some people like that.

A friend of mine regularly goes to the flea market, he has picked up at least two National Panasonic record players, the briefcase type (Cover is two speakers which you can place near the unit), for about $4...one needed repair.
And even otherwise, the most common domestic ones were Philips, and those went for $10-12 when last found.
Please bear in mind that records went out of production here in the late 80s, people had gone to cassette, which was replaced by MP3 CDs in the early 2000s...100 tracks on a 25 cent piece, little chance of wear.
That progressed to USB, cell phone, streaming.
So there is little chance of even finding stylii and cartridges here, and you have to pay what the sellers ask.
In that perspective, paying as much as a used car for a motor upgrade will get a response like 'Are you serious?' from me.
DC drive and a motor with generator...about $100 here.

- Ralf, Check back to my speed recording photo. The cost of my DC motor & controller (partial DIY) was under $100. This is a DIY site.
- Naresh, Most people have to order all T/T parts over the net, but there are plenty of stuff available, just serch

All the above ideas involve replacing the motor (and building a replacement controller) for what is a pretty high quality TT.
I'm sure the OP appreciates your ideas but I cannot see how any of these improves on simply replacing the 60 HZ pulley with
the correct 50Hz one and adding a small 240 -> 120V transformer
