motor control

Hi all! I am new here, so please guide me. I am currently working on a project which involves working with H-bridges for motor control. It is required that I am able to wire up the circuit and make it work. The only problem is that I am a Mechanical Engineering student, so I have no knowledge...

Hi, This post is more of a curiosity at the moment with potential to become something if I find a solution/idea. I am an extreme novice to all of this, especially motors and controlling them so please be gentle and patient. I most likely wont know many of the terms you use so please explain it...

I am using one machine (which has a small motor) which has battery of 1.2v which got dead and i want to change the power source to USB. The battery is of 1.2V and 400mAh. Motor connected to works perfectly fine if provide the 1.2V from bench power supply. I want to use USB power supply instead.

I've been using this MC2100 in conjunction with a pwm circuit I built, and had been using it successfully for a time on a bandsaw. I must have pushed it a little too hard when resawing a log, as the motor suddenly stopped in the middle of the cut. The behavior afterward was that turning it on...

I have to use a 94V battery to power a 24V DC motor and looking for suggestions on a motor controller that will help with the buck converter aspect and in rush current of the motor? Im a student so still trying to learn the best way to do this and was told this may be the best approach? The...

I am trying to control a linear drive motor with a built-in encoder. I am using a motor driver to move the linear motor. I have calculated a PWM signal for a PWM frequency of 1kHz and a duty percent of 50% with the following values: Internal Clock = 180 MHz Prescaler = 180 Arr register...

hi all I'm trying to control a 2 HP water pump works on one phase using 5V relay, but I feel it's not safe because it's pins are so thinner than the AC wires does using car cut-out relay will be good? should I use just one for the LIVE wire or two for LIVE and Neutral? note: contactors are so...

Hi, I bought a claw machine and there seems to be a problem with the motor control of the claw going up. when the claw is going up it will go for a brief period and then stop, the motor will stall and it throws an error (claw not going up) . Motor seems fine 28v 0.48a when powered with bench...

Hi, I work for company in the UK as an electrical engineer. I have just started at my new place and they have a 3-phase pump motor controller that needs replacing. It's a Coelbo Onematic controller, working off the pressure in the water line. I have a new controller unit but don't want to wire...

Hey everyrone, i have a question regarding a PSU i have at home (once used for a 3d printer). Its a 200 watt PSU 230V AC 2-3A (i think) step down to 24V (8.8A). I was hoping to jerry rig it to a 24v 12kW brushed DC electric oil pump (used for an emergency oil pressure system), i understand this...

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...
