I have a tight installation with a Leadshine ELM 2 motor, 1.3Kw, 130mm, model number: ELM2H-1300LD130F-H

I'd like to remove the motor's (aviation-style connector I think it's called? Name?) power cable connector and attach/splice the power cable's conductors directly to the motor's power wires that currently attached to the underside of the pins of the motor's power connector, then seal the opening left behind in the motor with a generous amount of silicone caulk. I've heard this is possible from a few people. (I realize this would certainly have to void any warranty, complicate future motor replacements/ cable replacements, etc, of course)

I'd like to have the wires exit at a 90 degree angle and run flush/alongside the motor, protruding less than 1/2" away from the motor's body, see the photo where I'm pointing with my finger at the base of the connector itself at the desired exit height and orientation (as you can see from the motor on the left in that photo, the connector causes the cable to protrude almost 4 inches away from the motor.

From the other photo with the orange plastic prying tool, you can see I have removed the 4 screws from (aviation-style? name?) power connector on the motor, but instead of the whole connector coming off of the motor tethered by the power wires from the motor itself reaching to the backside of the pins in the motor's power connector... Instead, the motor's power connector still won't move even with the 4 screws removed. I've tried GENTLY prying it up with a PLASTIC prying tool just to see if there was a gasket that needed some gentle encouragement to let go, but before I pry any more/pry any harder, I wanted to be sure this can be done and I'm not going to actually break anything.

No comment on the advisability of your proposed modification.

For information about that style connector, see:

Most people I have encountered call them "MS Connectors"

You might try prying beneath the flange of the receptacle first, so you can see the wire connections and see into the motor case. Then you might be able to judge better whether the riser on the motor case is cast in place, or fastened on somehow.

Or maybe that's what you meant to say you were already trying, and the position of your pry tool in the picture is misleading. With the four screws removed, there should be nothing holding the connector flange in place except gasket material or possibly some adhesive.

It's just called a "circular connector" and as Marc suggested try prying the circular connector off the riser first. With the screws removed attach the cable so you can use it for a little leverage. Slightly tap the 90° connector and see if the seal breaks. Those typically are sealed so they may seem difficult to remove at first. Without knowing the length of the screws you removed it's anyone guess if that riser is attached from the back side or not.

But they were made original for DC1 to DC3 Aircrafts, not for Audio

You can call it whatever you want, I'll call it by it's correct name.

An XLR connector, which is for AUDIO, it not the same thing as a circular connector. But I'm sure you already knew this.
