Hi I want to build a Locked Anti-Phase Servo with brushed DC Motor with dual power supply( +/- 24v for DC motor , 2 isolated 12v for driving). For testing I'll use a 20 KHz 555 PWM Generator. Opto are 2x HCPL 2630 not PC817. MOSFET will have diodes augmentation and big VDSS(... and rdson  )I could not find something useful on Internet so I have a question: - how should motor current be read for start/stall conditions? Please tell me any idea or links about this type of circuit Sorry for my english... Florin  |
