The incorporation of touch-based control into all different forms of electronics hardware continues, with the broadening of it pervasiveness increasing all the time. The convenient, intuitive operation this can deliver now has almost universal appeal. The first place in which widespread proliferation occurred was, of course, the consumer electronics sector, but steadily uptake has been rising elsewhere too, including in automotive.
Single-phase brushless DC (BLDC) motors have provided an inexpensive method for driving fans. However, even though Bill of Materials (BoM) costs are low, there is a couple of slight drawbacks in single-phase BLDC motors such as relatively low efficiency, noises or vibration by torque ripples.
Remember when as a child you were told not to stare into the sun because it could damage your eyes? It’s good advice – and not just because the sun is bright to look at. Our sun emits light across a number of different wavelengths, ranging from infrared through the deep ultraviolet – so if you stare too long into the sun you can give your eye a “sunburn” (which can cause permanent damage).
