TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched “TB9120AFTG,” a constant-current 2-phase stepping motor driver for automotive applications. The new IC ...

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 ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

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 ...

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, ...

Efficiency and power density are persistent challenges in high-current applications, particularly as systems become more ...

Unlike brushed varieties, brushless dc motors cannot be operated directly off of straight-line dc voltage. Remember, brushless motors use electronic commutation — so again, no brushes make physical ...
