Can't believe how lucky i am i have access to such well-explained technical content on topics i would otherwise have absolutelly no idea. Thank you so much!!
Man, stumbled upon this video in search of how to use a 160v DC motor we pulled of an old Tigerstop, where the controller gave out. I know nothing about electronics, only programming, and was just looking to learn how to even connect it to an Arduino. I have the amp board it connected to, and you just showed me what half the board does. I may not even have to create a new board, just find out where those pins from the 2, 2110's lead and connect to them directly.
Hi Lewis I have tested his design and it works very well. I have however made some changes both hardware and software. As Mosfet I used some IRF1405 which are higher in current for my needs. I made these changes to the software: 1) moved the arduino output pins to 3 and 11, this to be able to set a PWM frequency 31000 Hz without interfering with the Delay and Millis functions which would otherwise be altered by modifying the PWM frequency on pins 5 and 6 of the original soft.. 2) to change the PWM frequency I simply added this line in 'void setup' TCCR2B = TCCR2B & B11111000 | B00000001; // for PWM frequency of 31372.55 Hz in pins 3 and 11. The basic pwm frequency in 'digitalWrite' is low (about 900 Hz), the motors produce noise, and at high rotation speeds with the frequency modification they maintain greater torque and no noise, the Mos work even better. Yours is a great project, thanks for sharing it.
OMG, my son and I have been struggling with an H-bridge controller for an electromagnet for days. We finally got it working last night with the addition of p-channel mosfets but then discovered if the input voltage went over 8v it started to short out. Thanks to you, I now know we need a hi/lo ic driver! In the interest of time we'll probably go with an off the shelf solution for now but this was a great, relatively inexpensive, learning experience. Thanks for working out all the bugs and posting this!
thank you for this project. one question : how the cp capacitor going to charge and discharge while your code state that low side gate either a constant high or a constant low ? as i know for the cp to charge and discharge we need to inject high side with pwm and the low side with it is inverted one
Everybody note I ran some more tests. The gate voltage VCC can also be the the motor power voltage. I tested it at 12 and 15 volts and it worked fine. Do not exceed 15V for VCC.
Hi @@LewisLoflin , I wonder if I can drive a 90V DC motor with this circuit?. Also I have doubt with one of your answers. You said that circuit only need PWM signal on the high side gate activation MOSFET but when we interconnected HIN to LIN you also have a PWM in the low side gate activation MOSFET, is this a problem for the correct operation of the h-bridge?.

I have 25 v supply and i used voltage divider to the pins VCC and VDD of Ir2110. I couldn't drive the h bridge since MOSFET gate is not opening but the voltage is reaching the IC perfectly . I used the same circuit ,except VCC and VDD voltage supply ,and code but no use. Why is that???
@@LewisLoflin I supply 25 voltage to high side MOSFETs drain pins. This 25 v is divided 2 times to IC s VCC and VDD. So that's where I used divider . I also used PWM still mosfets not activated.
On the bottom right side of the 10ohm resistors...Are those components pull down resistors?? I don't see those components on your schematic..thank you..
And also you showed two pin to arduino but in the program you described ( #define) 4 pin, So should I assume that you are using four pins and not two as shown in the picture or you are using exactly two pins as shown in the picture?
were the outputs sinusoidal enough? im thinking of making a project on resonant inductive power transfer. will it be fine to use a coil instead of a motor used in this circuit. thanks
@@LewisLoflin OK. Thanks! You are my hero....btw. on your web page there is written: "....It does this without the use of p-channel MOSFETs or photovoltaic opto-couplers...." So now I am a bit confused :)
@@LewisLoflin ok..by the way.. do I need to provide 20V to Vcc of ir2110 when the Uge of mosfet is 20V? Now I supply +15V and do not know if it is enough...
@@map3033 There are two supplies here, the logic voltage in this case I also used to power Arduino, and the motor voltage. The gate voltage is created from the logic voltage.
For the bootstrap gate supply you need PWM to charge the cap, I get that. For the low side however, is PWM required? For example to get a 4 quadrant motor control with regen, you just run one of the two low side devices with the high side off. I also realize your code is just going for simplified H bridge motoring and not braking. Just figured I'd ask before I let some magic smoke out.
"Hello, how are you? Could you tell me what power supply you're using? I have a 12V DC motor, and when I connect a load, the voltage at the motor terminals drops significantly.
