motor control

Hi i have a 24V BLDC motor. I want to rotate the motor certain angle or laps. The motor have 3 pin that "+", "-" and "GND". I'm not sure what kind of ESC i need use for position control. I found some ESCs but these ESCs have different pin names that "U", "V", "W". What kind of ESC do i need use...

I have a customer that has a power washer hooked up to a Start-Stop Push Button control circuit. They want to add a timer where once the start button is pushed, will shut off the power washer automatically after a certain period of time (ie; 5 min). What kind of timer do I need to do this and if...

Hi I am trying to use a BLDC motor as a generator using the regenerative braking function. I have a situation where I need to be able to spin it while the e-lock is on, so I am thinking of using relays to open circuit the field windings while I do this. When I close the relays, I want to be sure...

Hello! Im an indoor electrican apprenticeship student and I need help with solving a task we we're given, since I can't seem to figure it out. A little context too: on the photo you can see a motor diagram, the thing is, when u press both the start buttons and all the contactors go down, you...

I'm currently doing my master thesis, and I'm now at a point where I have to control a few AC motors with a microcontroller. From my previous study about the subject, and from previous similar thesis, I've noticed a common practice is to use an optocoupler to separate low voltage from high...

Please see https://electronics.stackexchange.com/questions/610932/power-circuit-for-tb9051ftg-trace-width If anyone could offer more advice about the trace width I should be using for the power circuit for the TB9051FTG chip, that would be hugely helpful.

Hello dear Forum, I am new here. I don't have much knowledge of solar panels or motors... I was wondering how it would be possible to connect a small/medium solar panel (not too expensive) to a mirror ball motor (for a 50cm diameter disco ball). I don't have any of the materials yet, that's why...

Hi everyone! I'm Buse. I'm trying to control a motor speed for a personal project. You can find the schematic of the circuit I found on a book. This circuit works with only the PID parts contrcuted. My problem start when I add the other parts. For example, U1 opamp (top left) is supposed to...

I have a group project where I have to control the speed of a single-phase shaded pole induction motor. My plan was to use a Triac-based circuit however, all Triac circuits I have seen use a potentiometer to control the speed of the motor. In this project, the motor's speed is dependent on an...

I am designing an electric veichle controller for a University project. The motor driver receives an analog signal (0-12V) to adjust the speed. I use a digipot followed by a buffer to convert the digital signal of the controller to ana analog one. Now I need some way to enable an disable each...

Afternoon everyone, Getting rather frustated with somethign that seems straightforward to me... I have researched and corrected any mistakes I have made, done a rebuild several times, but can never get this thing to work. draws about 10mA on a 12V test voltage and thats it. nothing seems to...

I was looking into companies or startups that were doing things with motors to improve efficiency. I stumbled upon Turntide Technologies, which has a partnership with Amazon. Turntide is making a software-driven motor that "enables precise and reliable control to effectively use every watt of...

Just have to say at the outset that this forum is pretty awesome, and everyone is so patient with noobs (like me). I’m a woodworker looking to put to use the treadmill motor I harvested from my wife’s never-used treadmill. It’s a 4.25HP pmdc motor, cont duty at 130vdc/3171 watts. I had the...

Hi All, As an electronics engineer, I have always worked with low voltage circuits and found it very difficult to control high voltage, AC powered devices. In my last project, I needed a power board that I can just plug my MCU or DSP and control an instrument that needs high power. I wanted an...

I have been working on a circuit to turn a motor on for several seconds, and then off for a longer period, using a 555 astable circuit. The on time needs to be around 5-10 seconds, and the off time needs to be about a minute. To get around the 50% duty cycle issue and allow for a longer off...

I'm working on building an electric scooter and yesterday the speed controller had a MOSFET failure that I suspect was caused by inductive spiking. This was very surprising to me because I had a schottky diode in parallel with the motor to prevent this type of failure. I took the speed...

Hello, my treadmill pro-form 530zlt got burned control board. It has MC2100ELS-18W control board driving this motor. I'm stuck in difficult situation as after getting board running again motor has no torque, I can stop it by hand. I noticed that commutator brushes are giving noise and sparks...

Background: I'm working with an existing motor+driver board with Vin being supplied by a 4.2V LiPo -> TP4056 Charger Protection Board -> Boost Voltage Regulator. I've also got another subcircuit attached to the end of the TP4056 module through another voltage regulator and diode that powers a...

Hi, I am designing a motor control application (sensorless FOC control) using a fixed-point MCU. I understand I need to design a scaling system to handle all the motor parameter calculations, such as angle, speed, torque, etc. Would anyone please suggest where I should start? I only used MCU...

Hi guys, I’m a trainee in motor rewinding, due to furlough I’ve been pretty much working on my own the last 4 months so trying to teach myself to some success but also becoming stuck as I am now. I have an old Woods of Colchester 60slot single phase 8pole perm cap 220/240 volt fan motor. It’s a...
