A motor including a stator, a first connector portion, a selector, and a second connector portion. The stator has a first winding arrangement configured for a first voltage and a second winding arrangement configured for a second voltage different from the first voltage. The first connector portion is selectively connectable to each of the first winding arrangement and the second winding arrangement. The selector is movable between a first position in which the first connector portion is connected to the first winding arrangement, and a second position in which the first connector portion is connected to the second winding arrangement. The second connector portion is electrically connected to a power supply and selectively engageable with the first connector portion to provide power to one of the first winding arrangement and the second winding arrangement.

External voltage change device

A bearing shaft seal assembly for an electric motor positioned within an end frame of the motor in order to inhibit the passage of external contaminants axially along a shaft extending out of an end frame into the interior of the motor. The seal assembly including a first seal member, a second seal member and a third seal member; wherein the first seal member is a slinger washer mounted on the shaft so as to be rotatable with the shaft and which is positioned within an inner recess in the end frame, the second seal member is a concaved expansion plug positioned around the shaft and positioned within an outer recess in the end frame which is thereafter caused to be flattened so as to be in fixed relation with respect to the shaft, and the third seal member is a slinger washer mounted on the shaft so as to be rotatable with the shaft and which is positioned adjacent to the expansion plug. The seal assembly further defining a labyrinthine path designed to impede the inflow of external contaminants. The seal assembly further including a drainage slot to allow contaminants found within the labyrinthine path to exit out of the path.
