Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little ...

You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors ... uses six 2N2222 transistors to protect the Arduino from excessive ...

The efficient high-current operation of the new bipolar transistors from Zetex Semiconductors meets all the performance requirements of dc motor control ... of medium power motor drive circuits.

Class-D audio amplifiers and motor controllers in light electric vehicles. For driving LEDs and power factor correction are four 700V devices with max Rds(on) between 140 and 350mΩ, and then there is ...
