I have a BLDC motor to run at full speed for a brief time. The motor is equipped with three hall sensors. My question is, is it possible to realise the max speed control by setting the PWM duty cicle at 100% for controlling the MOSFETs, though the hall sensor commutation logic?
Will the motor...
Hi all,
I’m working on a project that uses a motor throttle and speed controller. There’s only one problem: the speed controller has three pins (see pictures for help) whilst the throttle has five. There is a red black and green wire for the throttle and then two more, presumably for the “on...
EPS Bench setup we are thinking about: Torque Angle Sensor (TAS) will be emulated by PIC microcontroller. Emulated TAS will be connected to EPS ECU's Single Edge Nibble Transmission (SENT) bus.
Our strategy in getting started with EPS Bench testing: Use PIC microcontroller to apply...
Hi guys, I am struggling trying to define an interpolation based on the below accelerator pedal map. The target is to define a calculation method that outputs the Torque function of the Pedal angle and the current vehicle speed. I am working on the software implementation of this system in C...
This is a table fan motor. The circuit is not working so I need to find a new one to start this again.
But I fail to get any online. Please help me to understand what I need to start this fan.
The fan has three wire: 1 - VDD 2- GND 3- PWM
Please find the attachments for your reference.
Hello,
I am a beginner at using Arduino.
I wish to do a very simple project.
If a user turns ON a water motor pump, it should give a trigger to my Arduino UNO.
Arduino will note the Motor ON time and date.
If a user turns OFF a water motor pump, it should again give a trigger to my Arduino...
Good day, all
Recently I want to use DRV8833C for a theory work What does an LC Circuit Do? Example Analysis, my first thing is considering the resonant frequency, here I have other questions to figure out:
1) Is the DRV8833C suitable for driving a resonant L-C circuit at resonance frequency...
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 constructed. My problem starts when I add the other parts. For example, U1 opamp (top left) is supposed to...
hello, I am attempting to build my own servo motors out of dc motor and optical encoders and 3D printed gears. in this way I hope to reduce cost and make precise toque servos.
my question is what internal driver ICs are suitable for it, and what are best encoders. please suggest any other...
Hi everyone,
I am making my 4th Year Project on Field-Oriented Control (FOC) with a BLDC motor. I am having the issue that with the virus outbreak I have had to modify a lot how to carry out the project. As a result, I do not know what to write about anymore. I would like to continue doing...
Hi,
I am looking for help with the wiring involved with controlling the speed of a motor on LabVIEW through a PC rather than changing it manually on my motor control card. I currently have the motor running in both CW and ACW directions using LabVIEW.
I know I must desolder the potentiometers...
Been having a clear out of old files, found this.
I captured this bit of schematic when I dismantled an old money counting machine, years ago. It's the power supply to an induction motor which rotates the pick-up rotor. The motor is shown by L1, L2 and the circle. Triac D2 looks like a...
