Motor electrical parameters
Posted on October 24, 2014 at 14:53Hi, I am not entierly sure how to correctly enter my motor parameters, and which effect they have, can anyone check if I am doing this correctly (sensorless operation with cordic startup, no extra features like flu...
How to include quadrature encoder I channel and secondary hall
Posted on October 24, 2014 at 15:01Hi Gigi, I currently browsing the library source code to see how I can integrate this start-up behavior: 1) start FOC algorithm using rough angle given by hall sensors 2) wait for I channel of quadrature encoder to...
Need recommendation for Full Bridge Driver
Posted on October 26, 2014 at 05:55I need a Full Bridge driver IC capable of at least 2.5 Amps at 125 kHz.The L6225 connected in parallel looks good but the highest frequency is only rated to 100 kHzIs there a higher frequency version of this or can...
Motor Electrical parameters Rs and Ls
Posted on October 21, 2014 at 02:19Gigi: I have a question, measured in workbench Motor Electrical parameters Rs and Ls. I see ST data is used RLC meter measurement frequency at 100 Hz, but the motor is running in the PWM 16K frequency, wheth...
Bad Overheating problems with L6474 , Help!
Posted on September 05, 2014 at 03:36I'm finding that the L6474 runs terribly hot even at 1.4 amps . Its on a decent PCB with 20 plates thru tholes a small heatsink (1'' x 1'') on the back and it will rise to 110 C in less than 2 minutes . It is the...
L6470H discovery Issues on two systems
Posted on October 02, 2014 at 22:29I am attempting to run the L6470H discovery kit with the dspin software from a machine with windows xp on it. I was previously able to run it from another machine with xp, I installed the same files but cannot conn...
L6470 High Speed Issue
Posted on September 18, 2014 at 21:39Dear Motor IC Forum: I am using an L6470 to drive a stepper motor attached to a gearbox and am not able to achieve step rates greater than roughly 700 steps/sec with any microstepping setting. The motor gets loud...
