Dear Sir, I would like to know how many PWM signals out can be created simultaneously on STM32F4. Cause I would like to control 5 BLDC. That is my concern. Cheers, George.

Not a motor specialist, however to drive the power mos in IHM boards, at least 6 PWM from same timer is typically required. (3+3 complemented). These are advanced timers (typically TIM1 and TIM8), so would say typically 2 motors.
