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 fo… ...

You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

He hooks up the SN754410 to two motors, giving him speed and direction control for both based on the duty cycle of a PWM signal entering the chip for less than $2.50.

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 ...

This pwm motor controller is using the fact that the small dc motor has the revolution speed depending on the power supply voltage. In this circuit the discharge time can be adjusted between 0.2ms and ...

The back EMF, along with the RL circuit in a brushed DC motor, brings non-linearity to the PWM control and the PWM frequency and PWM duty cycle become significant for getting the best output power.

The low voltage bipolar stepper or dual DC motor driver IC, has been launched by Allegro MicroSystems. The A3916 device is designed for pulse-width-modulated (PWM) control of low voltage stepper ...

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.
