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.
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!!
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!
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?.

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
"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. I think it might be the switched-mode power supply I'm using, but I'm not sure. If anyone has had the same issue and has already solved it, I would really appreciate your help.
At first glance this looks like it might work to run the typical 90V DC brushed treadmill motors. If so I can think of several projects that could benefit from having a programmable control interface.
@@LewisLoflin That's even more good news. Looking forward to the follow up video. You mentioned it needed to be pulse width modulated but gave no specifics. I'm guessing the Arduino programming description covers those details. Three applications come to mind. The first is a basic treadmill controller to replace an obsolete model. Second is a spindle motor controller for a manual or a CNC lathe. I have a couple of small lathes with treadmill style motors that I converted to cnc. The third application would be for those trying to build electric vehicles using surplus motors.
@@tenlittleindians That is on the webpage. The HIGH side MOSFET or HIN on the schematic must be pulse-width modulated. That is what controls the charging action of the 0.22uF bootstrap capacitor Cb.
@@LewisLoflin I found the link in your drop-down after trying the dead link web address posted on the schematic within the video. I was looking over your diagram and noticed you used a discontinued MOSFET. When I looked it up I noticed it had a far lower value than the 500 volts you mentioned. So I did a search for MOSFET chips designed for a higher voltage and found several that go far beyond your 500 volt limit. That's got me wondering which part of your circuit is limiting it to 500 volts? Not that I need anything higher but I'm just trying to figure out how this thing works. I had basic electronics in the 70's so I'm rather limited when I try and understand these things on my own. I'm in no immediate need of this circuit but I do sometimes like to breadboard things like this if I've got the parts laying around. (I don't have the MOSFET's) I also noticed you have a couple of LED's on your board but I don't see them in the schematic. Oversight or maybe the circuit was changed after you built the one shown in the video and in the photos? Did you point to point wire that on the bottom?
@@LewisLoflin hi I'm 'using it to make a remote controlled lawnmower with 2 24V 330W motors, to increase the deliverable current I have paralleled some IRF1405 which without cooling fins work very well over 50A
Hi, thanks for the great video. I have couple of questions 1. What are the n channel MOSFETS used in this circuit? 2. Will this circuit work fine for a 48v 5000W 3 phase BLDC motor? Thanks for your help!
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..
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.
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.
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
Sir, Question on HiIN and LoIn of ir2110. Shouldn’t there be a pause between the signal? Otherwise is there a chance that both mosfet gets open at the same time. HiIN and Loin are 180 degree apart from eachother.
I made an h-bridge basically utilizing this schematic to power some 120vdc (250-300w) motors I have. It works great for lower voltages such as 24v, but when powering higher voltage motors, I am getting some blown mosfets when powering off while the motor is spinning. Would redundant diodes across the mosfets help this failure? Mosfets are 600v 10a rated. Thanks for your helpful video!
@@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.
hi pls anyone know whats happening?: i only have IR2110smd in my area and i buyed it and i build exact circuit and here is problem, high side is allways full open i cant turn off and low side is sometimes work some times dont i dont rly cant get it Q:(where i but my arduino ground? , its means if i give 5V at HI - HO will puy out 15v?, if i give 5V at LI- LO will give 15v?) or (i connect my arduino ground at LI and PWM at HI?)
@@LewisLoflin if you don't mind , i made this circuit with irf1404 , i connected the ir2110 ground with motor power supply ground and the 15v(-) and 5v(-) , it worked fine with 12v 1amp motor then i used a 12v 7amp motor sadly the gate resistor of the high side and the low side blow up with the ir2110, could you give some advise for how to connect every ground or if you suspect the problem and thx
