I doubt if the output from a frequency contoller is a nice clean sine wave, and a synchronous motor has such low moving mass that it can easily lock to a poor waveform.

There have previously been threads about AC synthesis on this forum. The simplest solution is to use an op-amp oscillator feeding a small power amplifier then a backwards transformer to step the voltage up to drive the motor. If you use an IC power amplifier it really ought to be possible to knock the whole thing up quite cheaply.

Alternatively, why not just find out the price of a 60Hz Linn pulley?
