Resolved! TORQUE-SPEED RELATIONSHIP?
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...
Resolved! Run current limitation
Using SPINFamily Evaluation Tool 3.2, STnucleo-f401re and IHM03A1, I try to drive a 48V-9A motor. In SPINFamily interface, I choosed current mode and tried to set run current to 9A. But an error show up in the interface: "Power dissipation on sense r...
Adding Power Delivery
Hello.1- We want to add USB Power Delivery to an existing converter which can deliver 2x 5.1 V/3A from an unique power stage (isolated converter with one transformer, one regulator IC, etc.).The PD-controller has to meet the following requirements:-N...
Resolved! I need to build a Battery Management Unit for an EV with 80 LiOn cells.
I have an EV that was converted from internal combustion engine to electric using lead/acid batteries. It's been upgraded to LiOn cells but needs a battery management system to be safe and usable. I know several others with the same need. The L996...
Avoid back emf on steval-spin3201
Back emf from the motor is entering into other digital causing some issues. How can i avoid/isolate this back emf on STEVAL-spin3201
Resolved! How to configure POWERSTEP01 ocd_th in current mode?
Hi,Using IHM03A1, I try to drive a 48V-9A motor. I've set up the POWERSTEP01 driver in current mode, with default registers values, which works nicely but with low torque. Now I want to increase current up to 9A. I've changed IHM03A1 R1 and R2 resist...
SMPM motor vaibration and noise in mechanical resonance frequencies: 1.2Hz 2.4Hz 4.8HZ..
HiI'm running a SMPM motor and i have resonace problem in mechanical system resonance frequencies: 1.2Hz 2.4HZ 4.8HZ and in other frequencies everything is ok. The resonance is low it noload but worse in full load.I ckecked current controller,angle,...
Linux kernel driver for the L9823 ST chipset (digital output)
Hi Team, We are using the L9823 chipset and it is interfaced with imx9qm SOC over spi. Now, I gone through the code of linux kernel but I cann't see any linux kernel driver for L9823 ST chipset. can you please help us to get the linux kernel dr...
ESC Commutation, Noise and Max. Speed Problem
Hello Sir or Madam,We have designed an ESC according to STEVAL-ESC002V1 and used ST's 6Step_Library. In our application, There are commutation, noise and maximum speed problem. MCU and gate driver is STSPIN32F0AMOSFET is STL220N6F7Switching frequenc...
