This type of motor is probably the most commonly used in factories, lumber-mills, and other commercial plants. They are dual-voltage and can be wired for either 240VAC or 480VAC. Each motor will have 9 numbered leads coming out of the motor. The leads are numbered to aid the electrician when connecting the motor. If you look at the manufacturer's nameplate it will have a table similar to Table 1 that describes how the leads should be connected.
