3 speed switch not working properly

[fabieville]

My 3 speed switch is not working properly. I have a Cyclone Waterproof brushless Geared Electric BikeKit 1800-3000watt operating on 24v with a 40ah brushless controller as you can see in the pictures. Before the issue began I good get 3 different speeds from the switch but recently i was doing some work on the switch i was removing the wires from the switch and connect them to a different switch that I have and I forgot to cut off the power from the controller and after I was finish I am only getting 2 speeds from it now. I am only getting the lowest and the highest speed but not the mid speed. When I connect back the wires to the first switch is the same outcome with just 2 speeds I am getting now instead of 3. I am wondering if I accidentally shorts out something?
Did something got damage and what exactly? Is the issue happening from in the controller box or in the motor itself?

Is it possible to by-pass the 3 speed switch and configure the motor/controller box so that the motor is always running at the highest speed? Reason why i asked is due to the fact that I realize that without the 3 speed switch connected I am only getting the lowest speed.

Or was the motor actually getting 2 speeds and not 3 speeds as I was assuming because I see in a post where someone label a 3 speed switch as:
3-speed switch wiring:
White: Common
Blue: High speed
Brown: Low speed

In this case that would mean is only 2 speeds available which would therefore suggest that nothing is wrong with it then?

Normally with the switch not attached it defaults to the middle speed. Shorting one of the wires​ to ground gives​ low air and the other wire to ground gives high speed. I just have a bent paper clip shoved into my plug to jumper the high setting on full time

 

[fabieville]

so the motor speed/rpm is controlled by the controller box and not by any internal circuitry inside the motor itself?

if I am only getting just the 2 speeds from the switch does not means it is faulty or is just the way it suppose to operate?

I could have sworn i good get 3 speeds from it before, i just can't remember if that was the case.

Yes, its all in the controller, and yes, you might have jacked something up when it shorted to where you're only getting two speeds. It could be as simple as a burned out wire on the way to the board in the controller, but maybe not either...

 

[fabieville]

If I am only getting 2 speeds now is it the case that i am getting low and high or is it that I am getting low and mid speed?

I assume I am getting low and high which my only concern is to get high speed.

If I am only getting low and mid how could i set it so i am getting just high alone all the time?

How can I tell which two speed I am getting?

The motor is rated for 24-72v at 300-900rpm

After using a meter to find the ground color I just found a long enough stretch of flat road to test the top speed to find the others... But no way to tell from here about what of the three you have going. But once you find the fast combo you just leave it like that. I went with the bent paper clip in the plug method so I could pull it out and drop it out if needed.

what exactly inside of the controller box would control the 3 speed setting? is it a variable resistor?
Does anyone have a picture of inside one of those controller that comes with the 3 speed setting?

If the max speed at 24v is 300RPM would that be the highest speed available when you use the 3 speed switch?

It's all in the MCU chip, various manufacturers program them differently.

Some don't have any change between the different settings, as factory-programmed; some have only a little difference between the settings, most of them are a significant difference between them.

If the max speed at 24v is 300RPM would that be the highest speed available when you use the 3 speed switch?

Depends on the controller programming (either factory or user, if user-programmable; many are not).

Some of them don't appear to be a speed setting, but rather a power setting, or a current setting. (one that I have here only seems to have two settings, and is a current limit change, which by nature does limit the speed in that it takes more current to maintain a higher speed, but I never use it at a high enough speed to need that current at that speed).

If the max speed for the motor running at 24v is 300RPM would that be the highest speed available when you use the 3 speed switch?

You would have to test it on your actual setup.

If you still have the 3 spd with the other switch, the controller does work OK.
My guess is that you plugged the wrong combination of wires in the connector housing when you fitted back the first switch.

So is there a way I can know if I currently have the highest speed? As I ask before if the max rpm for the motor is 300RPM, When I was getting the 3 speed option from the controller would the 300rpm be the highest the controller could program to the motor because it would not be possible for the controller to let the motor pass 300rpm at 24v if the manufacturer already set that to be the max and if by Chance you want more rpm than the 300 you would have to increase the voltage from 24v to 36v or higher. Is that the case?
