Hi Kirk, Yup, I think there might be an error in the lister's description. Here are a few more links (thanks for the cut/paste tip!) In the US: http://cgi.ebay.com/Frigidaire-Frontload-Washing-Machine- Motor_W0QQitemZ180344630365QQ In the UK: http://cgi.ebay.co.uk/ARISTON-INDESIT-WASHING-MACHINE-MOTOR-part-no- C00046626_W0QQitemZ110335684899QQ Mine looks almost the same as these. It is 3 phase, rated 190 V 850 Watt, 230 Hz, 16,000 rpm. It has an encoder of some sort on the opposite end of the motor from the pulley - probably a low count device for speed feedback to the vfd. I have not run mine under load, but I would guess the the passive cooling is good and could easily be improved with a small fan. Like I said, I have run it up to 24,000 rpm or so and the (not so) little thing really hauls! With a balanced coupler, I see no reason why it would not make a decent spindle motor with excellent speed control when driven by a flux vector vfd in constant torque mode, especially if the vfd can be set up for PID control using the encoder feedback.
