Static Phase Converter Wiring Diagram Full Or Close

Wire the PHASE-A-MATIC static phase converter to the idlerSo, I was browsing the internet the other day, and found this: HD 3 - 10 Hp Static Phase Converter Mill Drill Lathe USA MADE one to three. Full or close to full horsepower (HP) can usually be obtained by powering the load motor through a 3-phase motor that runs on static phase converter is used 1. Static Phase Converter used to start an Idler Motor, Idler Motor to power the load motor.

A true digital output would show voltage on the 3rd leg. The 3rd leg can only be measured when the motor is running 'Only DPS check the voltage is the output voltage 2 phase and the output voltage 3 phase when the only motors movable'. I would take what should be a perfectly reasonable cut, and the spindle would slow/stop! I presumed that this was because the VFD didn't properly respond quickly enough to the increased amp load due to the other motor.Thus, I opted to see if this 'Digital Phase Shifter' would be any better.I got it in the mail yesterday, and it seems to function alright! It starts up perfectly on the first press of the power button, and the spindle spins at the correct RPM still.I did a somewhat 'heavy' test cut, and it slowed a little but didn't stop! I consider it a success.Now, these things seem pretty expensive (more so than the VFD!), but for someone who doesn't want to deal with a VFD and already has an electrical panel/wire-up they'd like to still use, these are perhaps just the ticket! They are very simply: 220v 1 phase (2 wires) IN, 220v 3 phase (3 wires) out!Seems to be just a static converter with what appears to be two start and 4 run capacitors.

In some cases with surface grinders the main drive motor is run off of a VFD, the ancillary drives are sometime DC and/or run off of a transformer that uses 2 legs of the incoming 3 phase power. I would recommend an RPC in this application. Phase Perfect is the only single phase converter that I am aware of that generates just the 3rd leg from single phase input that is pretty much sinusoidal, and can drive any types of loads up to its rated specs.Surface grinders do not do well with static converters, others that have used them in this application have noted irregular surface finish issues when using them. These require additional noise filtering and are only suitable for 3 phase input.
