GP100 general purpose TEFC motors are available in two configurations which exceed NEMA Premium® efficiency with our exclusive, leading-edge, die cast copper rotor design (143T to 256T) or meet NEMA Premium® efficiency with our die cast aluminum rotor design (143T to 449T). Either way, these motors significantly reduce operating costs and pay for themselves in a short time through energy savings. These industry workhorses are ideal for use in material handling, pump, fan, compressor and other industrial applications.
