Resolved! Which pin should drive Triac load ?
I am designing a typical TRIAC drive circuit, opto drive of the gate, snubber, transient protection etc. All app notes I read are saying that the load to be driven (in my case the primary side of a transformer) should be placed on the TRIAC's MT2 pin...
Resolved! How can I rotate my stepper motor for 1 single rotation using the L6472 evaluation board EVAL6472H-DISC along with the standard SPINFamily Evaluation Software GUI. I can rotate my stepper motor at a continuous speed.
I have created a .sfc file which I successfully write to my stepper motor. I need to drive the motor in Full step mode (which I am doing at present). Stepper motor is a 1.8deg motor - so 200 steps per complete revolution.
Resolved! STSPIN220 tiny stepper motor 1/256 steps don't work but perfectly find on nema17
So I have some tiny stepper motors I've been working with. Very small 8mm tall x 7mm diameter and coil resistance is 40 ohm. We're designing some tiny digitally controlled dial gages around these and wanted to direct drive the needles instead of tiny...
Resolved! Motor vibration/ noise due to parameter setting or resonance frequency?
Having problem on driving a motor with L6470 at speed range around 120 - 300pps where motor vibrates and making buzzing noise ,especially louder at 150 step/s, or mounting on a panel where the whole mechanical piece parts is vibrating together.Alread...
Resolved! In the application notes 1 kW traction controller reference design for 3-phase BLDC motors for light electric vehicles why 4 Parallel MOSFET and 3 separate MOSFET Driver is used.
Please explain the purpose of 4 Parallel MOSFET, Why we cant use 1 or 2 MOSFET with higher rating, Also Why three seperate MOSFET driver is used for each phases, Why single Driver with 3 Channel is not used. Whether it can be used, Please suggest any...
Use ihm08m1 to generate 3 independent PWM
Hi. I would like to know if it is possible to use Ihm08m1 to drive bldc with 3 independent Pwm...to not use complementary channels ? If so, is there an example how to drive l6398 correctly ?
POWERSTEP01 UVLO fault
We use POWERSTEP01 for Stepper motor control.We develop the own Board and tried to run the Stepper motor,Communication is done and response from POWERSTEP01 is Okay.only think Motor is not running and FLAG output is continually LOW due to UVLO.How to...
Resolved! Is provided ST tutorial on youtube (Motor Control Part5 ) support BLDC motors?
provided ST tutorial on youtube (Motor Control Part5 ) indicates it support PMSM motors .is provided FOC FW library support BLDC motors also?
L7980 / L7981 Sync pin capacitance?
I'm building a power supply and hoping to use 3 or 4 of the L7981 chips. I'd like to synchronize them using a single MEMS oscillator IC but need to make sure I don't need a clock splitter / buffer. As far as I can tell, the datasheet does not mention...
