Default possible TD-160 replacement motors...

First, you need to verify the AC voltage that goes to the motor. It usually is 110V(120V) @ 60Hz here in North America. But the Thorens may step it down with a transformer.
Once you verify the voltage, you can calculate the speed in RPM.
V is RPM
f is frequency of the voltage feeding the motor
n is the number of poles in the motor

so if f is 60Hz, and n=16, then the motor speed is 450 RPM
Several Ac motors are available to run 300 RPM@60Hz. You may just need a suitable motor pulley that is 50% larger. Eg: if the original pulley is 20mm in diameter, then a new pulley would need to be 30mm in diameter.

(original RPM/original pulley diameter)=(new RPM/new pulley diameter)
and solve for the new pulley diameter.

Thanks for the formulas, Nanook. Interesting stuff, though I doubt I'd be able to fabricate a pulley.

Keep an eye on eBay TD-160 motors show up pretty frequently..

Synchronous Motor Speed equation:

V= (2F x 60)/N

60 is the number of seconds in a minute (duh!)
V= output rpm
F = line frequency 50/60 Hz or any other value such as that provided by an AC electronic speed control (TD-125, etc)
N= number of poles

Voltage is not required.

Gives the same result as Nanook's equation

Hello! I am a new member. I see you said you have a td 160 out of use. I need a motor pulley for this turntable. Are you interested in selling the motor pulley of your turntable? If not, could you please inform the dimensions of the pulley, so that I can manufature one to replace in my turntable? Thanks a lot!

Hi, I'm new to the forum and looking for advice.
I'm looking at replacing a shaft on a TD 160 motor. I'm on a tight budget, so I'd rather not buy a new one as they appear to be quite sought after. The shaft has snapped and I have access to a machine shop where a new one could be made and pressed. Has anyone ever tried this? Is the shaft knurled or splined, or just a straight press? Could it be precision drilled out if pressing isnt an option?
Also, would anyone have drawings or dimensions for the pulley assembly? Is it with clutch or fixed to the shaft?

Any advice would be greatly appreciated.
