Great video dude. You are the one! Thanks for the controller video. It helped me a lot. I connected this ZM-7205A controller to a 1/2HP Hvac blower motor. Old motor pulled about 1amp @230vac with original Trane control module. With the universal controller, the best I can get is .7 amps or 180W. No where near the, 1,100W advertised. So my question is, has anyone verified that you can push 1,000w through this controller? What is your max amps. At 230v, I should be able to push up to 5 amps. The C setting does not seem to affect the max amps.
Thanks! Answering your question I got somewhere to 4 amps with different motor and high load, so I can assume that you can easily get advertised 1100W. Max power depends of power stage and here you have power stage based on IGBT SLLIMM module, not discrete MOSFET/IGBT transistors. In your case I suspect that nowadays controllers with their algorithms doing a very good job in controlling the motors. Controller here is based on STM32F0 clone chip. So, finalizing, if you had 1A on old controller and 0.7A on this controller, it does the job at least 30% better I guess. Cheers
Based on ODrive document, you need to count the number of permanent magnet poles/2. Example: Standard 6.5-inch hoverboard hub motors have 30 permanent magnet poles and thus 15 pole pairs.
Correct. Or, if you cannot see inside your motor to count the magnets, connect DC power supply with current limiter to any two of these three cables, give like 12V 1A or so(depends of the motor of course, don't burn it), and turn the motor with your hand. Amount of stable positions during a full circle is your pole pairs number. This is even better test, because sometimes you can have N and S magnet in one, or even NSNS in one magnet.
Mine would not allow the current limit to be set below 2 Amps, also the A setting in the range of 20 to 150 (200 to 1500 RPM) I could not set mine higher.
The pole pair of your motor is defined by the number of permanent magnets in your BLDC motor, which is always an even number. Since your motor has 27 coils it will most likely have 24, 26, 28 or 30 poles in order to have a good winding factor.
Hi, I'm hoping to use one of these drivers on an old washing machine motor like the one shown in Para-Dygmat's newer video to this one. They're 48 magnetic poles and 36 coils. If this driver can be set up to 8, do we divide the 48? As these are three phase then isnt the final number of poles a third of the total?
@@ianhelsbyservices I'm using a different model of this driver (ZM-BL2205T) so in my case it may be slightly different but the setting unit is the same BL01. In my case the pole number setting turned out to be pole pairs and not pole count. Although my motor has 7 pole pairs I had to select 7 or 8 on the BL01 as it doesn't allow odd numbers (which would only make sense when it's the total pole count). So I set it to 6 pole pairs and see the displayed rpm is 16.7% higher than the actual rpm. In your case the displayed rpm would be 3 times the real rpm when you set it to 8. Other than that it will run just fine.
@@ianhelsbyservices By the way, only the permanent magnet pole count matters for the driver configuration. BLDC motors normally always have 3 phases and having each phase on multiple stators doesn't affect the rpm calculation at all, it affects only the winding factor/performance of the motor.
@@LuukSteitner-ty6pc you are right! Only just got back to testing your hypothesis. Poles set to 8, display reads 250, actual RPM is 80. When poles set to 4, display reading 254, and RPM is 40. Have you tried interfacing your driver with a microcontroller?
thank you for the explanation. I have the same driver ZM-7205A , it works but my motor is a 36 pole bldc washing machine (/3=12 poles) as you showed it displays 10 poles and works only on 8, so do you have an idea how to do with 12 pole motor. Thank you again . Kader from Algeria.
@@krissio100 thanks a lot for your answer, yes it works at 8 poles but if it is at 12 poles it will be more powerfull and will run more smooth I think. actually , it runs at 1242 rpm (handheld display) it produces 400vac (multimeter) but can only run small engines not 3 phase ones, can you explain , with many thanks.
@@kadernouacer1583 I do not think BLDC motor is the same as 3-phase motor, in fact I'm sure they are completely different. Please search the internet for more explanation. And obviously the controlled will run only relatively small BLDC motors, because of the output power of the controller. Cheers
Hi! What is the potentiometer used for, which is installed on the BL01 setting unit, near the indicator? It signed as "-speed+", but nothing doing, when I rotate it. The speed of my motor changes only if I turn a potentiometer that is connected to the controller. What I am doing wrong ? Thanx!
Hey, can't remember now exactly but I was able to control the speed with potmeter on BL01. Actually it is a switch, just keep turning it, multiple turns. Try!
Hi, I cannot say for sure, I didn't try and original "manual" is very blunt. I've found this: "Motor positive/inversion signal: By controlling the conversion DIR high and low levels of the terminal, the positive and negative rotation of the motor can be controlled. Note: in order to avoid the sudden commutation of the motor at high speed and the huge impact on the motor and mechanical equipment, when the DIR end receives the commutation signal, the driver first slows down the motor until it stops. After stopping about 2 S, the motor changes steering. Speed up to set speed." Hope that helps.
Hi, I have to use the control board with a motor without a hall sensor but when I go to change the value in parameter H the new value does not remain in memory what can I do to solve the problem? Thank you.
H-setting is for hall, when its "ON" it means sensorless or WITHOUT hall sensors, and "OFF" means WITH hall sensors. Its counter-intuitive, yes. I couldn't replicate your problem, once I did "ON" it stays "ON" after power cycle. If I set "OFF" and hall sensors are not connected I'm getting "Error 1".
