I am not sure this question has been brought up before but I am unable to find the answer I am looking for so I have to make a post to ask here.
I have watch plenty of youtube videos and posts that demonstrate the cruise control feature of the Meguiar's DA Polisher G110V2 (or G220V2 for the place I am living at).
Typical scene in the video is the user turns on the machine, it spins, then applies pressure on top, and the sound of the machine changes, which is claimed to be an indication of cruise control in action (I do not doubt that), and then pressure released, the sound of the machine changes again to the state like the beginning.
Posts explaining the cruise control feature typically just telling the readers that there is a circuit in the machine, once it senses the pad rotation is about to bog down, it feeds more torque to the motor in an attempt to keep the pad rotating. It does not explain what means the circuit uses to sense the pad is about to bog down though (I do not blame that since this is more like electrical/electronic discussion). There is also no explanation on how far the cruise control can help at each speed setting used by the user.
So I have to make assumption here.
I am assuming the cruise control will automatically increases the speed setting when it is triggered on to a higher speed setting than the one the user is currently using. For example, if I was running at speed 3 on the dial, I press on the pad till it almost bog down, then the cruise control increase it to 4, maybe even 5 or 6 if bog down still continue to be sensed by the circuit.
Question:
(1) If my assumption is right, then, wouldn't it means that as the speed setting on the dial is higher, the effectiveness of the cruise control will be getting lowered?
Because if one was initially running at speed 1 on the dial, then the cruise control has room of adjustment from 2 up to 6 when it senses bog down.
If one was initially running at speed 5, then the most the cruise control can do is to bring the motor speed up to 6 and that's it, because that is the maximum, unless the machine has been programmed to automatically run above speed 6 setting which is 6800 OPM, a speed that cannot be selected by the user but can be selected by machine circuit. However I intuitively think that this is not the case, 68000 OPM should be the absolute maximum running speed of the machine, regardless of it is selected by user or program.
{ I expect some of you will comment that this is not the issue because as speed setting is higher, it is harder to get bog down. I agree. But I am not discussing this. I merely need a confirmation from anyone who has put the machine to this level of evaluation, be it from Meguiar's or non-Meguiar's. }
(2) If my assumption is right, so cruise control will essentially cease to exist when the user is running at speed 6 on the dial, is it correct to say so?
Well, because I assume 6800 OPM is the absolute maximum running speed of the machine. I knew from what I read here there is almost no people use speed 6 as someone stated before it tends to destroy the velco of the pad. But still I am curious to know the exact answer.
(3) How is the cruise control circuit senses the pad is going to bog down?
Does it senses the torque resistance changes on the motor, or it senses the increase in current pass through the motor coil as the motor is forced to spin slower, or some tachometer sensor around the free rotating spindle head?
(4) Can user select a speed setting in between the number on the dial?
For example, can I turn the dial to speed 3.5 and will the machine responses by giving me a speed in between speed 3 and speed 4, or will it just simply round it up to speed 4 or keep at 3.
(4.1) If intermediate speed can be selected on dial, what is the minimum step of increment? 0.5 (half), 0.25 (quarter), or even smaller step?
I am assuming the dial is a digital dial and not analog dial (if it is analog then one can have infinitely many option of speed between 0 to 6).
(5) Does the speed number on the dial snap into position when it is turned to a number (as in there is a "click" mechanism) or just turn smoothly from 0 to 6?
(6) The G110v2 (or G220V2) has been advertised to be a machine with the most versatile OPM range in the market, from as low as 1800 OPM to 6800 OPM. I have seen a lot of posts regarding the use of speed 3 to 5. I recall I seen a post where someone use speed 6 and the velco on the pad get destroyed so speed 6 kind of "prohibited" from using. But does the speed 1 has any practical use to you before?
I have never seen a post where the user use speed 1 to achieve something. I am curious to find out the practical use of this speed setting. Otherwise the existence of this speed setting to me will just be a marketing strategy with little to zero practical functionality. Nevertheless before I jump into that conclusion I think I better ask here first. So please enlighten me.
(7) My survey indicates that most DA runs at almost the same speed range, usually from 2500 OPM to 6500 OPM (Meguiar's has 1800 OPM). However the power rating is a lot different. Some is rated 850W or above, but yet the maximum speed is still 6500 OPM. Why the high power rating when the machine only can run at the same maximum speed? It costs more to pay for the electricity so there got to be something else to gain otherwise it make no sense to get a higher power rating machine.
The reason I ask so much is because I am getting ready to go into the domain of machine polishing and over here there are not much DA choice available. Two most easily available options are the Meguiar's G220V2, another is the Ultramate 880W DA polisher (an almost identical model to the more popular Kestrel Das-6 Pro sold in the UK).
Over here the G220V2 is sold in a kit set (link here) and cost about US dollar 500. The Ultramate also sold in a kit set (link here) and cost about US dollar 265 (all after Google currency conversion). Meguiar's one year warranty if I recall correctly, Ultramate 6 months. So one is twice the price tag of the other. Hence I really need to understand the machine as much as I can before I pull the trigger. So please bear with me if my detail questions annoy you. Ultramate has a lot more power rating but no cruise control, and higher speed 1 setting OPM (2500 OPM) compare to Meguiar's 1800 OPM on speed 1. Both have about the same maximum OPM speed. Ultramate is heavier I believe.
