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 ...
Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...
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 ...
A few characteristics of dc motors maintain linear relationships that allow for very predictable operation. First, if enough voltage is applied across the terminals of a dc motor, the output shaft ...
The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...
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 ...
ROHM has developed two new motor driver ICs for brushed DC motors, BD60210FV (20V, 2ch) and BD64950EFJ (40V, 1ch). They have been developed for use in home and office appliances such as refrigerators, ...
The global automotive closed loop current transducer market is exhibiting consistent, low-risk expansion as vehicle electrification and power electronics complexity continue to reshape automotive ...
