Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for ...

In this case, they’re being used to create a basic PWM motor controller. The trick is to set the 555 up in astable mode, and use diodes and a potentiometer in the charge/discharge loop.

As solutions in mobility, <a href=" target="_blank">aut<a href=" target="_blank">omation and robotics have exploded in the ...

When the analog signal's magnitude exceeds that of the carrier, the PWM ... control. In simultaneous switching schemes (Schemes One and Two) power flows repetitively between the motor and dc ...

Maxon Precision Motor's ESCON 50/5 OEM module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can efficiently control permanent magnet brushed DC motors (PMDC motors) and ...

PIC33A DSCs from Microchip provide high performance and reliability for complex automotive Electronic Control Units (ECUs),” said Norbert Weiss, managing director at Lauter ...

Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it can reject PWM slew rates of >500V/µs and settles within 500ns to provide a 0.3% accurate (of full-scale) ...

Adding to this are vector control methods that give the AC drive the capability and flexibility of a full DC motor drive. Fig. 1. Essential elements of a PWM motor drive. Fig. 1 shows the ...

Toshiba has introduced PC-based design tools for motor control, as part of ‘MCU ... and support for PWM frequencies up to 156kHz. The firmware caters for motor types, including brushless dc, permanent ...
