This is yet another project born of necessity. It’s a simple circuit, but does exactly what it’s designed to do – dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate ...

This application note presents Z16FMC microcontroller used to control 3-phase brushless BLDC motors in a sinusoidal PWM modulation mode. It discusses the ways in which to implement sinusoidal PWM ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Motor control algorithm which detects the rotor position at standstill, with different pulse width modulation control allows the motor to be controlled independently of the applied mechanical load, ...

Graceful Shutdown: Ensuring the motor and controller are shut down safely when the application is stopped. If the application operates on a multicore MCU/DSP/FPGA, an appropriate inter-core ...

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

Designed for pulse-width modulation (PWM) motor control, the A3948 integrates on-chip DMOS output transistors in an H-bridge configuration. Consequently, the motor ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

SunFounder has sent me a review sample of the Fusion HAT+ Raspberry Pi expansion board designed for motor and servo control using audio interactions with ...
