I have a Gates CB500 that I am refurbishing. The CB500 has a Ashland hysteresis synchronous motor with the following specs:
0.25 A
600 RPM
single phase input
1/500 HP
2 MFD cap
I am burnt out on DIY projects (just finished 2 monoblocks and the Gates CB500 turntable). So, I am seeking a AC motor drive that is off the shelf.
Full disclosure: I know nothing about motors and drives / controllers. So, be gentle!
I ran into a couple of different alternatives on the internet and would like your thoughts. One of these is cost conscious and the other, high end scientific equipment grade.
Anaheim Automation KNC-VFD-CV20-1S-0002G - Variable Frequency Drive
cost: $113.00
link: https://www.anaheimautomation.com/p...em.php?sID=788&serID=88&pt=i&tID=1105&cID=385
summary: With 120VAC Single-Phase input, this drive offers up to 200 Watts (0.25 HP) of power to drive your Three-Phase AC motor. This series offers unique control methods to achieve high torque and accuracy, and variable speed range.
Then, this next option is an all out product that has phase angle adjustment which, if I understand correctly, should be beneficial. Please correct me if this is not necessary.
Amp-Line AL-150-CV-GPIB-3
Cost: TBD, but definitely not cheap. I am inquiring with the supplier.
link: Multi-Phase Programmable Power Sources | Amp-Line, NY
summary: phase angle adjustable multi-channel programmable power sources are either constant current mode or constant voltage mode power sources. They are equipped with functions to adjust the output amplitudes, output frequencies, output phases.
So, please let me know your thoughts. If there are other off the shelf alternatives to consider, please let me know.

I use an adaptation of what some call"ipod drive" in which a two channel 60 hz file, the channels 90 degrees apart, is amplified and fed through transformers to the motor. The run capacitor is not used; its function is to generate the 90 degree delayed sine wave(approximately 90 degrees, and with higher voltage, both of which produce vibration). Resistors have to be added to the amplifier output, since the transformer windings have zero dc resistance, which overloads most amplifiers.
I use a program called Cognaxon, a free downloadable 2 channel frequency generator which allows phase shift to be set to two decimal places(or is it more?).
The transformers I use are instrument transformers, 20:1, 480 to 24 volts, used in reverse to step up the output of the amplifier.
The amp is 20w, very cheap. 4 ohms of resistance, 10w resistors.
Total cost $100 or less(excluding the computer).
Motor cannot be felt to be running. Mine is a permanent magnet motor; your hysteresis motor should perform even better.
i have to set up the program every time, others use a permanent file, even a cd. The program used is Audacity, i got better results with Cognaxon, probably because Audacity only allows time, not phase shift.
