STM32 MCUs Motor control

On what does the value of resistor r​41 and r55 depend I tried increasing shunt resistance but the measured current value when I start the motor is very high​.I am not ​getting the current value accurately.The motor spins in open loop and when it shifts to closed loop it starts oscillating and draw very high Ampere​

I have motor controller and i have to communicate with it using can bus, problem is the manufacturer hasn't provided can can codes . I want to display all the messages available on bus so i can manually figure out the codes for specific functioncan anyone give any link to refer to complete this task

I use STM32CubeIDE (1.5.0) as a toolchain without a current CubeMx file. What is the means of upgrading motor drivers from 5.4.4 to 5.Y.4?I have done the basic install of 5.Y.4 under folder C:\Program Files (x86)\STMicroelectronics but in my CubeIDE project the drivers are duplicated under folder: C:\Users\Brian\ST_workspaces\Bitbucket - repo -v03.10.02 - New_Filter\cascade_pfd\Prysm_Test_Board_LLI tried replacing the 5.4.4 folder in my project with the 5.Y.4 folder but get a build error. I then edited the path in Project//Properties/Paths to the new folder location of 5,Y.4..Are there any notes somewhere to go through the steps of upgrading the motor drivers?Thanks,Brian

Look at this forum! Almost no one is getting answers for their questions from ST!I have received one answer from ST only. I guess I am lucky. Thank you. I asked 3 more questions - no luck.I have opened the case with online support, It was "escalated". Still no answer.What is the point of the product if you are not providing some minimal level of support?Did anyone even successfully tested the STEVAL-SPIN3202? Or I just wasting time following ST "manuals"?

I asked a question before on the routine SPD_GetAvrgMecSpeedUnit but the answers did not address what I was looking for. https://community.st.com/s/question/0D53W00000xsTlzSAE/information-on-the-c-code-procedure-spdgetavrgmecspeedunit-This routine returns the average mechanical rotor speed and is called every Medium Frequency Task (1ms). The routine itself returns a pointer to SpeednPosFdbk_Handle_t..I can't seem to find where the average speed is actually computed.? It is a moving average computed over STO_FIFO_DEPTH_UNIT samples (currently set to 64).The Medium Frequency Task occurs every 1ms but the motor FOC calculations are updated every PWM period. Is the speed of the new sample put in the buffer calculated over 1ms or is it a "instantaneous" value measured between PWM periods?My concern with the moving average filter is the linear phase incurs a large phase delay even at low frequencies (see bode) Thanks for any help you can give,Regards,

I have a motor control board built around the STM32F446RET6. I was updating code using motor control workbench to alter the control parameters.After an update, I was no longer able to use the motor control workbench console to communicate with the board through USART3.Here is the sequence of events that 'broke' the link.I had the motor control working fine. The motor would spin, and motor control workbench was functional and allowed me to monitor speed, make adjustments, etc.The speed was incorrect. I traced that to incorrect motor settings, which I changed.After changing the settings, the motor started up, and the current waveforms were quite good. However, the control shutdown on a speed feedback fault.There are 2 speed 'observers' available in the ST micro package. 1 is PLL based, which I was using, and was clearly superior in the original prototype testing. The alternate was based on an algorithm called 'CORDIC' that I did not have much success with.Since I changed the motor parame

We are developing a BLDC Motor controller for E-Cycle which is a 24V 250Watt power. The Motor is a Hall sensor type and for the evaluation we have an existing Motor and trying to run the Motor with the help of Evaluation board STEVAL-STSPIN3201. The project example 6S_STEVAL3201_HS_VM  is taken and modified in a new folder to change my Motor specs.I have followed the below documents to do it.1. UM29162. STSPIN3201 SchematicsThe following versions of Softwares I am Using:1. ST Motor Control Workbench : 5.Y.22. STM32CubeMX : 6.3.03. IAR Workbench : 8My Motor remains in the Stall condition only and does not move. I am continuously getting Speed Feedback Error. For that solution I referred to the link below.https://community.st.com/s/question/0D50X0000BaLTMc/speed-feedback-fault-in-motor-control-workbench-monitorNow, When I am using ST MC Workbench GUI for running the Motor, It shows the Motor is running but actually there is no movement in the Motor.

Dear ST,Could you please advice on the correct positions of STEVAL-SPIN3202 jumpers to run an example with ST MotorPilot.J9 - BOOT0 Open or closed? J7 - RX - TX Open or closed, Could you please explain why would we need to connect RX and TX? Which of the following ports is correct for use in ST MotorPilot? Seems that COM3?Where can I download a bin file to test hardware for this board.Regards,Edward.

I want to use two powerstep01 or L6470P drivers to make circle on my cnc. Can I do it using SPI not step/dir interface?

First thingI am trying to XOR, 3 pwm's and If the xor output is 1 "motor is on" otherwise "motor is off".I am getting 90ns deadtime. I mean between the pwm's there is some gap. How to encounter this situation? ( I wnt to use a gpio and Im using a nucleo - h743zit6) I want to use TIM12 channel 2, external clock mode

Hi, I am fairly new to motor control and ST software. I am trying to setup a bldc hall sensor motor with the MC workbench tool to control speed for now. I am using the b-g431b-esc1 discovery kit. I have wired the motor to the kit as described in um2516. Now when I use the Mc workbench monitor to try and control the speed, as soon as i start the motor it ramps to the negative max rpm of the motor and the speed control does not work utilizing the gui. I have tested the hall sensor to make sure theyre in order 100,110,011 etc. Not sure how to fix this.I have setMotor specs:Maxon brushless 1 pole pair, 3 Amp peak, 24 Volt nominal 5K rpm max. 60 degree placement electrical angle between hall sensors.softwaremotor profiler 5.4.8stm32cubemx 6.3.0(latest version couldnt work with kit)cubeprogrammer 2.9.0stm32cube 1.8

First of all it works for me just as I wanted: Using prescaler "4" increments CNT every 4 encoder detections. It solves problem of CNT overflow in bigger resolution encoders. I know it could gain errors every motor direction change, but this is not a problem in application.I found informations that this solution doesn't work for people and shouldn't be used. What is STM's official position?

Hello,When working with an incremental encoder, after performing the encoder alignment procedure, it is imperative to perform the function MC_StopMotor1();Otherwise, the current (Id ref) is incorrectly set, which can lead to overheating of the motor.This problem is especially relevant in the position control mode, since in this mode the motor stop function is not used. Best regards.

Hello EveryoneI'm using FOC control for a BLDC motor. It works fine, but there's a situation that I can't solve.I'm using a trigger as input: when pressed, the motor starts and must remain running until the trigger is released. If the user press the trigger and maintin it pressed there's no problem because motor pass through IDLE->ALIGN->START->RUN states and when the trigger is released I can call MC_StopMotor1(); so motor stops.If the user press the trigger and after a short time release it, I've to wait motor in the RUN state to call MC_StopMotor1(), because if I do that with motor in the state ALIGN, START or START_RUN, it stops but next time I'll call MC_StartMotor1(), the system will be stucked in IDLE_START state, and precisely in the R3_2_CurrentReadingPolarization() function, in r3_2_f30x_pwm_curr_fdbk.c file.I've tried to cheat the state machine generating a B2G event via software (break event that is generated by an overcurrent), but the same result has been occurre

I'm trying to adapt a piece of BLDC control firmware that already works for the STM32F0 family for use with an STSPIN32F0 chip using a STEVAL-SPIN3201 board. But for some weird reason, I am unable to figure out what's going on with the gate driver, and the manual doesn't shed any light on this.According to the manual, the gate driver must first be enabled by asserting F0 or F1 (or both) high. The high side is connected to pins A8,A9,A10 whereas the low side is connected to B13,B14,B15.But as soon as I run this little snippet:void main(void) { RCC_AHBENR = RCC_AHBENR_GPIOFEN; GPIOF_ODR = 0xc0; // F6,F7=11 GPIOF_MODER = 0x00005000; // F6,F7 (push-pull) for (;;) {} }... the HSU, HSV and HSW pins go high, i.e. the high side mosfets become open. There's no way to physically check what's going on on the pins between to MCU and the driver since they are both one chip, but logically they must be floating, and there are also internal pull-downs on all of them. Why is the high side open by d

Hi,I try to perform high speed rotation on EVALKIT-ROBOT-1, my target rotation speed is 6000rpm without loading.I downloaded the example firmware "STSW-ROBOT-1", change values of "DEFAULT_TARGET_SPEED_RPM" and "MAX_APPLICATION_SPEED_RPM" from 4550 to 6000.In main(), MC_ProgramPositionCommandMotor1() is directly called with parameters which equivalent to 6000rpm (run 2000*360degress in 20sec), then use MC_GetMecSpeedAverageMotor1() to track the motor speed, the maximum speed I got is around 3800rpm.According to the document "https://www.st.com/resource/en/user_manual/um2653-getting-started-with-the-evalkitrobot1-stmicroelectronics.pdf", Table 10 states that the system with no load can reach 4550rpm.Figure 7 shows that continuous operation speed can even be higher then 6000rpm.I am using the original set of EVALKIT-ROBOT-1 hardware, It cannot even touch the official speed 4550rpm.Should I change other configurations to achieve the target speed?
