text: <s>[INST] Single Phase Output on Drives Has anyone ever tried to single phase out a PowerFlex drive, or know of what needs to be done to try this? I didn't think it was possible, but a customer has been doing it with a Moeller drive (440/460V) and was also told by the local Siemens distributor that their drives can do it up to 230V. Any suggestions? Is there perhaps a unique firmware configuration that would have the IGBTs firing off in a single phase configuration as oppose to a 3-phase? If this is possible, it would create a new motor control market. Cheers. [/INST] The output phase angle of these drives is 120 degress per phase which will not work with single phase motors. You can get a single phase motor to rotate if it is unloaded, but it will not produce much torque. Drives that are designed to control single phase motors must be used. I have used a drive to control a single phase permanent split-capacitor motor, but that required bringing one of the capacitor leads out of the motor and connecting it to the third output phase of the drive. The cap didn't last very long having to deal with the PWM. \\n </s>
