Pulse width Modulation, BEMF and BEMF induced current
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...
Resolved! Hi, We are planning to use L6491D in our application.
We had the following queries:1.Pins LIN is mentioned as active low.Will the low side PWM output from driver be high when input to LIN pin is low?2.VCC is mentioned to be between 10-20V.But all input pins(SD,HIN,LIN) are operating at 5V level.Is there...
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,...
