160 Results for "bldc"

Controlling a brushless motor (BLDC): Hardware
Log from FlexSEA: Wearable robotics toolkit
The BLDC schematic consists of 3 copies of the Half-bridge sheet (motor commutation), the Shorted-Leads protection circuit, phase voltage sensing and bridge temperature sensing.U7 (temperature sensor) is routed close to the power MOSFETs. Figure 13 shows...

Encoder for the bldc test bench
Log from Self standing balancing robot
Rotary encoder 600 steps encoder link CAD Model nRF52 Firmware After the failure to use the qdec peripheral, fallback was on pio, interrupt, but that gives another advantage, the one of capturing timestamp on the nRF for every event, so that the log...

Plan for an improved BLDC controller
Log from prism laser scanner
Rotating polygon laser scanners need to keep track of the angular position of theprism or mirror.In an earlier version of Hexastorm, this was achieved with a Sharp A160 polygonmotor. This board has a NIBC3111 chip. Motor speed could becontrolled by sending...

Slim Cycloidal gearbox with the BLDC motor in the middle
Log from 3D Printed Robot Actuator
41:1 Dual Disk, Single stage27mm x 102dia QM4208 motor, 6809 Bearing

Second BLDC is Installed (and giving me trouble, of course)
Log from TrillSat
The replacement BLDC has been soldered in place on Circuit Board C, and the new ZIF ribbon cable connector seems to work pretty well. However, since I'm trying not to wire on top of the BLDC this time, I've just about run out of room for the circuit...

New Thruster layout, BLDC driver rabbit hole and Embedded Linux
Log from Aruna - ROV
New thruster layout design The current thruster design of the ROV is quite agile with the 6 motors the submersible is able to move in 5 dimensions. With the front (1 and 2) en back (3 and 4) motors being able to use to go in 3 dimensions (X axis, Y...

Log #9 BLDC Hybrid drive with "2-speed Shifter"
Log from Hoverboards for Assistive Devices
While I was experimenting with controlling the speed of the H/B drive wheels, I realized that really slow speed control was difficult to achieve with reasonable torque. This is unfortunate, because I'm anticipating needing slow (safe) speeds, but...

PIN Assignment
Log from Field-Oriented-Control Stepper driver
The two current sense ANALOG input´s are assigned to ADC12_INP4 and ADC1_INP2, which should make it possible to use the dual ADC mode, for simultaneous samples. That leaves ANALOG temperature (thermistor) port and ANALOG voltage_divider (BUS voltage)...

Ground truth torque testing
Log from K3lso Quadruped
Ground truth torque testing for #tmotor AK10-9 and #mjbots #moteus I didn’t dare pushing it further today when everything started to lift even if I tried to hold it down by hand. 😅 #k3lso #quad #quadruped #robotics #bldc

Getting Started: The ESC
Log from Modified ESC for Bidirectional BLDC Control
First, what is the goal of this project?We require a brushless motor driver to control BLDC motors with, for the development of our humanoid robots. Without an effective, simple and cheap controller, we cannot build our robots. Simple!BLDC motors offer...

Printing started
Log from Dizzy Wolf
Based on my learnings from BLDC controller and custom motor, I'm now going to build and assemble actual 4-legged robot.I have started printing parts but I don't have much to show yet. Just this.I have bought DLP printer by the way, but have not...

Brushless DC motors: microcontrollers & drivers
Log from Supercon talk: a pragmatic guide to motor controls
BLDC motors are effectively Steppers with three coils instead of two (often called 3-phase.) That means three half bridges and three PWM signals will turn the motor. In fact, if you open up a hobby ESC you'll find six mosfets and either an 8051 or AVR.BLDC's...

Developing the Power module (Part 2)
Log from EverywhereElectric
In the last log we showed how the physical inverter design came about, lets look at the motor control signals are generated.We keep going on about sinusoidal control. Here is why.Brushless DC (BLDC) motors are called so because they followed on historically...

Cheap, plentiful, accurate part nozzles.
Log from P2 - Pick and Place for 3D Printers
The stainless steel 2.0mm hollow shafts for part rotator idea number one showed up today. I set to work rebuilding the BLDC motor with it. It was relatively painless. Pressed out the old shaft, pressed in the new one. ...

Electromatronics
Log from Kinesthetic Laser Rifle Prop
To make this 'gun' feel like a GUN, I will require some electronics and other hardwares.First, a list! I love lists. Especially numbered lists. They make me feel like I am accomplishing something even though I am not...Components by 'function'::1. the...
