    How to spin your stepper motor more efficiently – Part 2

    In part 1 of this series, I provided a few key ideas: TI hearts stepper motors. Stepper motors can be power-hungry. Back electromotive force (EMF) will indicate the stepper-motor load. You can control the output current based on back EMF. This can help save some power. No talking about current regulation! So now that all of...

    Simple BLDC motor spinning 101: Five key concerns

    The brushless direct current (BLDC) motor is the newest member of the big motor family that people just can’t stop talking about. Unlike a brushed or stepper motor, control techniques for which are very mature and standard, there have been debates on what’s the best approach to control a BLDC motor, as well as how to continue improving these...

    How to spin your stepper motor more efficiently, Part 1

    It’s no secret that we love stepper motors here at TI. We love them so much that we work to come up with integrated circuits (ICs) and development tools that make stepper motors easier and easier to drive. We have small-form-factor BoosterPacks to encourage prototyping; innovative product features like adaptive decay to eliminate motor tuning;...

    Motor start-up techniques: Part one

    In parts one , two , and three of his blog series, Yisong Lu discussed different “sensorless” start-up techniques for three-phase synchronous motors and specifically how these techniques are applied to the DRV10x series of integrated motor controllers. In this three-part blog series, I will discuss the start-up options for TI’s high...

    Designing an energy-efficient BLDC ceiling fan solution

    Rapid advancement in power electronics technologies and wider availability of highly integrated ICs to embed motor control algorithms now makes it easy to use a brushless DC (BLDC) motor instead of traditional induction or DC motors. BLDC motors do not have mechanical brushes and commutators so they provide higher torque/power-to-weight ratio, run efficiently...
