Hey guys,I would appreciate your thoughts on this. I have presently implemented 6 PWM schemes to modulate the 2-level 3 phase inverter I am using to control my BLDC motor in a simulation. Those PWM schemes are shown in the figure below I observed tha...

I have a question, I am presently working with a bldc motor. And I also did a simulation on matlab.So I observed this:1. when I applied a certain load torque (let’s say 0.4Nm), then I give my controller a set point speed (400RPM) the controller is no...

Hi All,Can anyone point me to a material to use in configuring a general timer on stm32 to interface with the 3 hall sensors from a bldc motor and How to estimate the speed from it?

HI all,Does anyone know how to configure the One Pulse mode on this chip using the HAL library?I tried producing a constantly on-pulse on a timer by setting the CCR value to be greater than the ARR value. And it produced no outputP.S: I accounted for...

Hi All,Presently my systick timer is set to 1ms. Does anyone know how to configure that to be set to 1us? Also can It be set such that it increments by 0.1us?This is the present clock configuration Here is the present system clock configuration code ...

Hi @Cristiana SCARAMEL yes Now i get it. It is important to also state that for the purposes of motor control, the operating point actually shifts across different torque speed characteristic curves. This is true especially if the terminal voltage ...

Okay that makes sense looking at the relationship between power, torque and speed.But does that mean that if I apply a certain load torque on the motor’s shaft. Then the maximum speed I can get is fixed at that operating point determined by the load ...

I think the problem is more hardware based, my design is a bootstrap circuit, so I think my bootstrap capacitor cannot be turned on for so long.However, the low-side MOSFETs -- which is not bootstrapped -- gets turned on for long.

It is the Advanced timer TIM1.Here is the configuration code/** * @brief TIM1 Initialization Function * @param None * @retval None */ static void MX_TIM1_Init(void) { /* USER CODE BEGIN TIM1_Init 0 */ /* USER CODE END TIM1_Init 0 */ ...

Hi Amel,This has been very useful.Can you also help with links to a multchannel ADC using DMA and timer trigger?Many thanks.
