Motors:

The electric motors used in California Turbo transformer cooling fans are supplied with 406 stainless steel shafts for ease of maintenance, extended length shafts for superior support of the propeller, and removable condensation drain plugs to provide longer bearing life. Motors are rated for dual voltage: 115/208-230 V, single phase or 208-230/460 V, three phase, 50 or 60 Hertz operation. All of our motors are manufactured to NEMA MG-1 standards which requires those motors to provide their full nameplate horsepower at ±10% of their nameplate voltage, ±5% of their nameplate frequency.
