motor control

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...

I was looking at the FAZ-NA line of circuit breakers by Eaton, and I was wondering if the capability of these to provide short-circuit interruption and thermal overcurrent protection removes the need of an overload relay. It seemed strange that these branch protectors were so much cheaper than...

Hi there, I am making a servo using a wiper motor, Arduino and potentiometer. I need a motor driver the one in the tutorial I am following uses a IBT-4 Motor Driver, unfortunately it will take two months to be delivered to me. Are there any alternatives for this which will do the same function...

The submersible motor in my home works when it takes 13A on starting using a starter board. But nowadays on starting it takes 15A when turned ON and no water comes from ground. So how do I reduce the motor current from 15A to 13A. If you need some data related to starter I could provide that too.

Good afternoon, I have developed a Vector Control for a PMSM motor in Simulink using Simscape Electrical but my motor is not spinning. I have tried applying various speed values but nothing happens. I am applying a step signal from 0 to 300 but the motor speed still doesn't move. My error...

Hi everyone, I am trying to develop an FOC algorithm (see screenshots attached) using the Motor Control Blockset in Simulink but I am getting the following errors (see screenshot attached). I don't know waht I am doing wrong since I fed my d and q currents to my Discrete PI controllers and fed...

Hi everyone, I am trying to implement FOC algorithm in Simulink using the Motor Control Blockset. I want to simulate the iPower Gimbal Motor GBM2804H-100T with the Surface mount PMSM block. However, I don't understand what the LdTrq input is or how to set it up. SInce it is a motor I do not...

Hi everyone, I am using a Discrete PI controller for an FOC algorithm I am developing in Simulink using the Motor Control Blockset. I would like to use a Ki gain if 2. At the input of the block, I have an input labelled Ki*Ts. If I use my gain with a sampling period of, let's say 1ms, should...
