Here is a circuit that will output a PWM wave good for varying the speed of a DC motor. Why is this not going to work? How would you fix it? The 555 timer can’t handle that type of load, and it is not ...

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 ...

This PWM Controller circuit is ideal for controlling small motors with 2A maximum current consumption. For higher currents you need additional cooling for T2 and increase C2 value. This pwm motor ...

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, ...

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 ...

Maxon Precision Motor's newly released DC servo motor controller, the ESCON 50/5 OEM module. This mini OEM plug in module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can ...

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 ...

Having reviewed the basics of BLDC motor control in Part 1, the design effort canbegin.. The first quest is to select a microcontroller. Looking in themarketplace there are several microcontrollers ...

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 ...
