Posted on October 15, 2013 at 13:48Hy, i must build a new board for control Stepper Motor. The pwm control logic and all, is manage with new cortex STM like STM32F100RBT6B. I want an unique 3V3 logic supply for all, is possible drive and receive al...
Posted on October 02, 2013 at 17:40Hello I understand: 6470 uses voltage mode drive/bemf compensation 6472 uses current mode drive/adaptive decay comp compensation If my uStep requirements are 1/16. What other parameters should I consider for my de...
Posted on October 20, 2013 at 01:31Hello I would like to ask to the experts a question regarding BLDC motor control. I am currently trying to develop a Brushless motor controller that allows me to control the torque and speed of the motor. The motor...
Posted on October 13, 2013 at 13:34Hello, I am not sure if this is the right forum to post in. My question is about the L4891 PFC controller, Is there any calculator for extracting the inductor value, and all other values? Its going to be a very com...
Posted on October 12, 2013 at 12:38Hello,I design the automation system with using l297 and l298 chips. Where can I find safety parameters of this chips (MTBF, MTTF, SIL or FIT) ?Thank for answers. #l297 #sil #mttf #mtbf #l298
Posted on April 18, 2013 at 16:45HI , 1.can any one tell me how to PWM DC motor using L6205 ,via EN pin or INX pin ? 2.how can i make the motor coasting (in PWM OFF) ? for the Table in the Datasheet when EN=1, if IN1=0,IN2=1 => OUT1=GND...
Posted on October 08, 2013 at 11:09Hi. Using L6470 I need to move to absolute position with the possibility to change speed during motion. I need the Soft Stop (or something similar) when reaching the target. Speed change during motion is possible ...
Posted on October 01, 2013 at 05:34Hello, I am using L6480 stepper motor driver. I have connected my board with SPIN software. If I run the motor status is shown as motor is operated. But in this case High side MOSFET's (HVGA1 & HVGB1) does not turn...
Posted on October 04, 2013 at 15:16Hi. I played with the eval board+steval to set my step motor parameters. It works flawlessly. Now I'm writing Arduino code to get the same control. Motor parameters have been copied by the Register Map. SPI routine...
Posted on February 12, 2013 at 12:13Dear All,I would like to design a 52W LED Driver (140-270 VAC) with output 36V, 1.5A and with efficiency > 90%. Please suggest and help me.Thanks in advanceKarthick #led
