This note covers operation and applications of the HCNR200 and HCNR201 high-linearity analog optocouplers. Internal operation and the servo control mechanism of the optocouplers are described in ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

Allegro Microsystems, LLC releases a new high current integrated DC motor drive IC, the A5950. Allegro’s A5950 is designed for PWM control of DC motors and capable of peak output currents up to ±3 A.

Brushless dc motors have the advantages of high reliability and smaller size, but the absence of brushes can pose challenges. One challenge is the requirement for electronic commutation and control, ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
