Recommendations for a synchronous linear motor or PMLSM
I'm looking to build a small linear motor, that could move or just accelerate an incoming load with permanent magnets attached along a path, like a touchless conveyor belt. https://en.wikipedia.org/wiki/Linear_motorIt might have as few as 3 or as man...
HVLED001A - issue with start up
Hi, I built my QR flyback supply for master diploma in study but I have issue with startup. When I'm starting from low voltage the transformer get strange noises to circle about 160V but I'don't have power on output, on 230V transformer is very silen...
FOC Model in Simulink WITHOUT Simscape
Has anyone developed an FOC motor control model in MATLAB Simulink WITHOUT using SIMSCAPE? I find SIMSCAPE too confining to model the 3-phase brushless motor and interfacing signals to non-Simscape blocks.My challenge doing this is to implement SVPWM...
Resolved! Viper265KD - How can I make a 5V design with this IC while it's VDD treshold max is 14V and supplied from output voltage.
I have a 85-265AC input and desired to have 5 volt output buck converter.How can I make the viper265kd to perform 5V output?When I check AN5380 the VDD is supplied by output voltage which is 15V and it's enough to supply VDD min requirements.I need 5...
Resolved! STSPIN840 EN/FAULT pin management
Hello,I have some question about use STSPIN840.Page 19 in datasheet, R_EN and C_EN's value are 39KΩ and 10nF.In the graph that is the basis of the recommended value, the value of V is 3.3V.Also in page 18, FAULT and EN pins in MUC are tied Driver's...
Resolved! Stepper motor moves To and Fro
Hi,We have used L6208 for driving bipolar stepper motor in our application. We would like to run the motor in full step mode. We implemented the circuit given in the datasheet on our PCB. When we program and try to drive the stepper motor, the shaft ...
Resolved! ST1S14PHR failure
Hello everyoneWe use ST1S14PHR to reduce from 40V input to 15V output. 15V are used to drive Mosfet (BLDC Motor Control). Lately we had a lot of problem with ST1S14PHR, because some parts failed during on field operation. We cannot understand what is...
Resolved! minimum and maximum RPM using FOC
hello,is there any recommanded speed limits (in rpm) to get an optimal and realiable speed control using FOC?thank u :beaming_face_with_smiling_eyes:
