Wiring and controls for motor.

I'm building a drum sander and need some advice on wiring and controlling a feed motor. I've done basic wiring on tools like this before (plus, motors, switches) but this one is a little different.
I need a high torque, low speed gear motor - such as a wiper motor https://www.ebay.com/itm/1536993156...FPzb12ZRKu&var=&widget_ver=artemis&media=COPY

Controlled by a pwm to adjust speed, like this https://www.amazon.com/Controller-Governor-Industrial-Conveyor-Control/dp/B0969RZG4W

And a power source to go from 110/120 VAC such as https://www.amazon.com/Enclosed-LRS-50-12-MEAN-WELL-Switching/dp/B07CTTZRYS/ref=mp_s_a_1_3?crid=2RC5XR96A80HW&keywords=mean+well+lrs-50-12&qid=1667361276&qu=eyJxc2MiOiIwLjY3IiwicXNhIjoiMC43OSIsInFzcCI6IjAuNTQifQ==&sprefix=lrs+50-12,aps,167&sr=8-3

Are these to right parts to achieve my goal? If not what would you suggest? I want it to work as intended and be safe. Since it will be in a dusty environment, can I put that power supply in a seal box to protect it? Lastly can I run this off from the same cord as the main motor (1 3/4hp, 115v, 15.5a) through a 20a dedicated outlet?

Thanks for any help.
