FOC+HALL UVW phase current curv problem

I use FOC+HALL and the motor reduction rate is 1:1.But the phase current(one of UVW phase) is not sine wave as figure.Is it normal? how come the U/V/W phase current curv is not sine wave?what problem cause that?Thanks

Alternative package for battery charger STBC02 except BGA

We are designing a system and We are taking Power management schematic as it is from STEVAL-MKSBOX1V1(SensorTile.box) as it is best suitable for our system .but We don't want to use BGA package and battery charger STBC02 has BGA package.so is there a...

How to get active power with STPM3x..

I am using STPM33.Reading 70 registers using UART was a success.Data received ex)A0 00 E0 04 00 00 00 F8 A0 00 A0 00 E0 04 00 00 00 F8 00 F8 00 F8 00 F8 FF 0F FF 0F FF 0F FF 0F 27 03 27 03 00 00 00 00 7E 77 7E 77 07 40 83 06 00 00 72 10 72 00 08 06 3...

I would like a reference design and detailed specifications for the STOD32W,

I'm using a tiny oled drive

Is there a quick start guide for EVSPIN32F0251S1

For the device STEVAL-ISV006V2 how can change output tension from 5.5V to 2.85V

We do not find in documentation formations about R4 R10 and R2 adjustments ....and how can be used.

Motor rotation become backward/negative direction problem

I use FOC+Hall and try to start in forward direction by speed mode as below:MC_ProgramSpeedRampMotor1(200/6, 200) MC_StartMotor1()but the motor become backward directionI found at STC_CalcTorqueReference() function, the return value SPD_GetAvrgMecSpe...

HALL_MAX_PSEUDO_SPEED question

HALL_MAX_PSEUDO_SPEED questionat HALL_TIMx_CC_IRQHandler() function, how come the "if condition" become TRUE, then assign HALL_MAX_PSEUDO_SPEED value to pHandle->CurrentSpeedI found that the motor is not rotated, but the HALL_M1.CurrentSpeed value is...

SRC0CS25D fail

I have 3 boards that shares same power input schematic from battery power. I use SRC0CS25D to control power up of board. First two boards works great.The third board works, but the 3 sample which i used for debug purpose, after a while they fail to p...

IHM02A1 stepper motor driver with red led (FLAG signal) always ON

Hi,I've connected a IHM02A1 expansion to drive two stepper motor on a Nucleo-F302R8. I've followed the user manual UM1964 to setting up the example both in the standalone version and in the UART version. I can't achieve to have the motors move and I ...
