B-G431B-ESC1 - Fine shaft position control
Hi,In my application, I'd like to control the position of the motor shaft instead of the speed, since I have more than one motor and I want them to move in phase (they are connected and controlled by CAN). I saw this board has the possibility to add ...
What is this method of driving BLDC?
Hey guys. We are trying to drive a 350 watt scooter sensored bldc motor.we use common circuits available online and we use gate drivers(ir2103) with 6 n channel mosfets to swith between phases.In every step we pull one phase high and one low and the ...
Speed Profile Wizard
I'm trying to drive the stepper with SPINFamily Evaluation Tool 3.2.I have:X-NUCLEO-IHM03A1NUCLEO-F401RETamagawa TS3641N1E1 Stepper Motor (connected as Bipolar)From stepper datasheet i got it's parameter and with oscilloscope I calculated the Ke.Now ...
STBC15 datasheet inconsistencies
Hi,STBC15 datasheet indicates that BAT pin should bypassed with a 4.7uF and the OUT pin with a 1uF ceramic capacitor. On the other hand, a typical bill of material (BOM) is suggested in page 2. Here there is no bypass capacitor on BAT pin and the OU...
[Motor Driver full H-bridge VNH5050A-E] PWM maximum frequency problem
I had a problem with this component VNH5050A and I need your support.ﾠMy test bench is composed by:A PCB board (created by myself), where I solder the VNH5050 with the same resistors and capacitor shown in the typical application found on datasheet.ﾠ...
3 phase Rogowski coil based current sensing IC
Hi,We have a requirement of measuring/sensing 3 phase transformer current (1000A range) using rogowski cable .The output of this cable is fed to the low stage gain and high stage gain integrator circuit and it is then fed to the microcontroller .The ...
6 Step on B-G431B-ESC1?
Hi All,I am attempting an in-application comparison of FOC vs 6-step using the B-G431B-ESC1. I have it running well with the FOC. However, despite the data-brief indicating the board can run the 6 step algorithm, I cannot find any firmware bundle to ...
I want to use VNH7012AY , but I don't want to use STL76DN4LF7AG MOS , can I use resistance or capacitance replace STL76DN4LF7AG MOS

Reactive and Power all over the place when consumer is switched off or disconnected.
Setup:1. Using STPM33 eval board with shunt & 110V, connected to ~1500W/700W heater, connected as in Figure 8.2. Teensy3.2 connected using SPI.3. Heater is turned on and off and also connected/disconnected from the plug during measurements.4. Pooling...
shape of current waveforms measured at shunt
So, I'm expecting the voltage developed across the shunt resistor to be sinusoidal, but I'm having much difficulty measuring these on the STEVAL-ESC001. The shunts on that board are 10mOhms, and perhaps the current through the motors is too low to ...
