Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motors ...

Reference platforms are powerful yet simple-to-use development tools built around leading-edge microcontrollers whose feature sets and performance characteristics are optimized for use as motor ...

Cheap, brushless motors may be the workhorses behind our RC planes and quadcopters these days, but we’ve never seen them in any application that requires low-speed precision. Why? Sadly, cheap ...

Power Integrations created Motor-Expert 2.0 with the design engineer’s needs in mind. The new tool reduces the cost and complexity of BLDC drive design and works with the newly released three-phase ...

Allegro MicroSystems has announced a 3-phase sensor-less brush-less dc (BLDC) fan driver IC with sinusoidal outputs to minimise audible noise and vibration. The chip, called A5931, includes output ...

This application note describes a three-phase brushless DC (BLDC) motor control using a sensorless algorithm. This cost-effective solution is based on the Freescale Semiconductor MPC5606B device, a ...

This source code supports Microchip's Application Note AN1160: Sensorless BLDC Control with Back-EMF Filtering Using a Majority Function, which describes a sensorless Brushless Direct Current (BLDC) ...

This article describes ongoing internal project activities at eInfochips in the control systems domain for applications in motor and engine controls aimed for aerospace and automotive segments.

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.
