diffrences in sensored and sensorless BL motors?

[justneedspeed]

what is the difference between sensored and sensorless Bl motors? Thanks in advance

A sensored motor and controller senses th exact position of the armature at all times. Therefore it can apply the right power and Viola!! no cogging.

Sensored motors have separate sensors, and an additional five wires, that tells the controller which direction, how fast the motor is turning and the exact location of the rotor. Works well for stand still high power starts, no cogging.

Sensorless motors use the wire that is deenergized while one of the coils is being energized on the other two wires. It gives out "back EMF" created by the rotor to the controller. The controller will sense and calculate where the rotor is and use dynamic timing for different rotor speeds. Works well with higher rpm motors. Less parts to break. Has option to use "ramp" or "soft start" method, until controller finds location of rotor from back EMF. This can help prevent cogging.

Sounds just like the motors in CNC machines - very expensive!

Maybe I'm thick but I'm confused how to set my 100 X-Power ESC.
I have the Program Box from OSE and have set all the usual settings for my Ammo 2300 running on 4S lipos but the last option is " Timing Monitor - For brushless ESC with no sensor"
Do I set this to ON or OFF ?????

Hullooooooooo any input
If I choose the wrong setting will it damage anything or will it just not run ?

I haven't used the speed control or motor, but i'm pretty sure the ammo is sensorless. If it was you would have a plug on the motor for a 5 wire cable. Therefore I would set your esc for brushless esc with no sensor.

Yes, Ammo is sensorless.

Hi Guys
Yes I know the Ammo is sensorless ( it only has 3 wires) but do I set the Timing Monitor to ON or OFF.
Graham.

[ReddyWatts]

Leave it on the default setting.

It says the timing monitor is to "prevent motor burnout".

Cheers guys, I have set the Timing Monitor to ON.
Sorry if it seemed like a dumb question
