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 ...

A friend asked me if I could develop a low-cost power driver for toy/hobby DC motors ... datum of the motor then observed is summarized below. This circuit can easily be built on a standard ...

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 machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor.

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.
