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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

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

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 ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

The DPW Series pulse-width-modulated dc motor-speed control designed in a compact SMT package. The RoHS-compliant models are rated from 2 to 10-A continuous output at 120/240 Vac. Machine Design ...
