The motor is a Baldor 1 h.p. TEFC 3 phase on a Teco VFD. The small pulley is ~1.75" and the larger is ~12", shaft is 3/4" X 36". One belt is 80 gr, the other 120 gr. At about 40% (~24 Hz?) on the VFD is just right for grinding. Lots of pyrophoric iron chips coming off, handle with extreme care...
Regards,
Rob
