Understanding Motor Lead Configurations
The number of leads on your three-phase motor determines your wiring options. Motors with more leads (9 or 12) offer voltage flexibility, allowing you to wire them for either high or low voltage depending on your power supply. This is especially useful when pairing motors with phase converters, as you can optimize for your specific single-phase input voltage.
At Phoenix Phase Converters, we've helped thousands of customers properly size and connect their three-phase motors. Whether you're setting up a machine shop, woodworking facility, or industrial operation, our American-made rotary phase converters deliver clean, balanced power to keep your motors running smoothly.
