Looking at controlling a HVDC motor like so -
- Type DC781 (2) LSG
- Operates on 6 - 220 VDC
- 84 ohm terminal - terminal resistance
- No load speed of 8000 RPM @ 220 VDC - 100 mA
- Stall current at 220 VDC: 2.6 A
I would be using 120VAC input however
My questions are can I turn this on and off with a relay? What would be the best location for this relay, to the motor or from the AC connection? I imagine there may be issues with the inrush current.
Basically can I use this circuit replacing the "Power Switch" with a relay like this - https://www.digikey.com/en/products/detail/panasonic-electric-works/ALZ11B05W/645567
A rectifier (400V rating, 4A) - https://www.vishay.com/docs/88655/kbl005.pdf
Also what capacitor would I need or do I need it at all? Quick napkin calculation implies I'd need a huge cap, but I imagine a ripple doesn't really matter for a motor like this? Is this accurate that I can skip the cap entirely? And since 170VDC peak from rectifier averages back out to ~120VDC at 50-60Hz anyway? Correct?
And lastly selection of a thermistor to limit inrush current. I am unsure on what parameters to select here, I imagine just current.
