Review on 🔁 CHANCS TYC-50 Synchronous Motor Cup Turners: Ideal 110V AC 15-18RPM CW/CCW 4W Solution for Electric Fireplaces & Tumblers by Will Randles

Now I've gone through 2 of these engines. One failed after about 100 hours of operation, the other after 430 hours of operation. For my application, I had a maximum drag of 3 oz in a 5 inch radius (0.085 kg / 12.7 cm). This corresponds to the equivalent of 1.08 kg/cm. This motor is sold with a declared load of 8 kg/cm. So I'm not even using 15% of the rated load. Both failed in the same way, the torque suddenly disappeared and soon after that they were all almost dead. The seller assured me that these motors have to be operated at high temperatures (70-90°C). Unfortunately, when they run at such a high temperature, they also begin to release liquid lubricant, which causes its own pollution. Unless you have a VERY light job, do not use these motors as they are grossly overpriced!
