Hello,
Right now I am working on a project to control a 3 Phase BLDC Motor by designing my own controller for it. I have specified different control operations (feedback, voltage/current monitoring), but before I figure those out I need to make sure I can drive my motor with my basic controller.
I am using a 48V, 20Ah hub motor from Conhis Motor. I also ordered a controller from the company to make sure my motor works correctly which it does. I have attached the designs of my gate driver set up as well as my H-bridge status. We are using STP40NF20 MOSFET for our H-Bridge and IR2110 gate drivers
We are using a dsPIC33fj16GS502 to generate the PWM signals that are being input into the gate drivers. I've also attached how we are setting up our 6 PWM signals. Our signals are from 0V to about 4.5V, well above the gate driver's 3.3V minimum input.
Currently when we set everything up we are getting a flat 10V-ish output on the gate drivers and no movement on the motor. Any help will be very helpful.
