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=(120Xf)/n 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. __________________ stew ☮ -"A sane man in an insane world appears insane."

Synchronous Motor Speed equation: V= (2F x 60)/N Where: 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 __________________ "To argue with a person who has renounced the use of reason is like administering medicine to the dead." - Thomas Paine Last edited by kevinkr; 30th June 2010 at 05:10 PM.

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!

 24th February 2012, 12:14 PM #15 cgrey diyAudio Member   Join Date: Feb 2012 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. Thanks
