Controlling motors is probably one of the first more advanced output-type applications, once they’ve mastered controlling LEDs, that most engineers tackle when learning to program microcontrollers. DC motors allow an introduction to speed control using a pulse-width modulated (PWM) output, along with directional control too. Stepper motors introduce control concepts that provide precise angular rotation, while driving brushless DC motors (BLDC) can range from the simple to using algorithms based upon advanced mathematics.
To guide design engineers to the appropriate solution for their application, Toshiba has prepared a webinar that provides an insight into the latest technology innovations and products around these three major motor types. For example, H-bridges for DC motors are available that utilize the latest BiCD process technology. This ensures, thanks to the low on-resistance of the in-built MOSFETs, that as little energy is lost as possible during operating. BLDC motors, such as those used in low-torque applications like fans, can benefit from Intelligent Phase Control. This makes sure that the commutation point is continually adjusted to its optimum value, reducing energy consumption. Finally, by continuously adjusting the gain when controlling stepper motors, torque can be maintained to hold the rotor in place but without delivering unnecessarily large amounts of power.
