Problem for EVAL6482H
Posted on July 22, 2014 at 21:47I have used EVAL6482H board to drive a stepper motor with a spec as followed,Operating voltage: 2.5vRated current/ phase: 0.49ASupply voltage: 20vI set the parameter as followed Stepper.setParam(TVAL_HOLD, 0x02); ...
Current readout circuit problem!
Posted on August 17, 2014 at 10:32Gigi or Dino: I met a strange question, motor parameter in STM3210E+ MB495 successfully entered the closed loop control. Now I redesign custom board, The open loop mode debugging hardware correctly, when...
BLDC motor control at 60000 or more RPM
Posted on July 03, 2014 at 12:06We are working on a Medical Respirator equipment, for which we need to control the BLDC motor up to 60,000 RPM. To generate a speed of 60000 RPM, Space Vector Modulation PWM waveform main/base frequency shall be 4 KHZ...
V/Hz control of an ACIM
Posted on July 01, 2014 at 16:16Hi, I would like to control some small 3 Phase Induction motors with means of an analogue input and a potentiometer. I am looking at a V/Hz (Scalar) library that I could use with an ST processor. Can someone direct m...
STM32 SVPWM modulator
Posted on July 20, 2014 at 15:17Hello, I am looking for solution of SVPWM implementation for STM32F103 microcontroller. My application is AC motor frequency converter with U/F = const regulation. Best regards Andrzej #stm32 #3phase-motor #frequen...
FOC Control and Resolver input
Posted on July 29, 2014 at 18:04Hi, I have a PMSM which I'm planning to run sensor-less. In case I run into problems with the sensor-less the motor I'm using also has a resolver fitted. I have a Resolver Decoder from analog devices so I'm wondering...
L6470 step loss A (or B)
Posted on July 21, 2014 at 23:12i've been using the L6470 driver successfully but have noticed that i get step loss on the a and b bridge. the data sheet indicates that when this happens the appropriate bits in the status register get set. unfortuna...
L9958 SPI control
Posted on July 22, 2013 at 15:39The question is related with the command word under the SPI protocol title. In this protocol uC should sent the command word to start protocol but I can not find the structure of this word. In datasheet the CFG_REG an...
L9942 - Motor lose some microsteps
Posted on August 08, 2013 at 20:17I want to control a stepper motor (http://pt.farnell.com/astrosyn/163/stepper-motor-1-8deg-5v/dp/9598650) with L9942 from ST.But i have some problem because the motor dont rotate uniformly (lose some step): My curre...
