Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude Pulse width modulation is a form of signal ...

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 ...

We use DC fans in many systems in our day to day life. For example, CPU fans, fume extinguishers and many more appliances which we make use of, are operated by DC. This is a project used to control ...

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 ...

Allegro announces a new full-bridge motor driver IC that is designed for bidirectional pulse width modulated (PWM) current control of inductive loads and is capable of continuous output currents to ±1 ...

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 ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...

Toshiba is offering its first single-chip sensorless motor controller as an application specific standard part which offers full-wave sine wave PWM motor drive output. Intended for brushless DC (BLDC) ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

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 ...
