This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

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 ...

An ATmega8 was used to build this circuit which can be used to control the DC motor found on toy car wheels with gears through IR remote control. For controlling the speed, forward and reverse ...

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 ...

ROHM has developed two new motor driver ICs for brushed DC motors, BD60210FV (20V, 2ch) and BD64950EFJ (40V, 1ch). They are ...

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

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...
