Treadmills use 3 phase motors, but run off single phase power. The “control board has a built in vfd. That motor can run off 120 or 240 volt single phase with a VFD. What power your treadmill needs 120 or 240 is the question, and the motor can’t tell you that. Look up the manual for that treadmill, and call precor or the people you bought it from.
