Hi, I bought a Q100C 36V350W rear driving hub with 328RPMs and a KU93 controller from BMS battery. In mode 1 I have no problems but when I switch to mode 2 or 3 the bike accelerates but sudddenly there comes a screaming sound from the motor and it stops. I have to reset the controll panel to make it work again. I also tried the thumb throttle only (no PAS) with the same result. It seems to me that high loads are the problem. I got an old KU65 from a friend and with this controller everything worked fine. So I ordered a KU65 and got a controller named KU63/65 cause the old one is no longer availibe. Here I have the same behavior as with the KU93. Does anyone have an idea what the problem could be? What would be the right controller for the motor?

S06S 24V/36V controller from Bmsbattery or 48V version of S06S (called 48V sine wave something) from aliexpress is the correct one.

The Q100 328 is a very high speed motor and can be hard load for some controllers, especially if installed in wheels 26" or larger.
It is generally thought that the KU93 doesn't match with the Cutes, but the KU63's/KU65's have been used with the Q100 by many of us.
The "screaming" (I would call it screaching) indicated a Hall sensor problem.
Double check the little pins in the white nylon connector to make sure they are all in the right place and haven't backed out and double check the color matches.

I'm using the Cute100H with a KU63/65 and did have a pin for the Halls back out. Definitely makes the motor noisy and reduces power a lot. Fixed it and it is back to its normal self. Not huge power on hills even with 44 volt Multisports 16000 ma, but it does make you pedal!

I don't know if there is a difference between the Q100 and Q100c but i built for a customer this combination...
The Q100 261rpms @36v matched with ku93 and a 48v battery and it runs smooth as silk.
