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 ...

Controlling a small dc motor without speed control sounds ... S 1 can be a manual switch, a relay contact, an optocoupler, or a transistor. If you close S 1, Q 1 turns on, and the motor runs. Figure 1 ...

That’s because brushless DC motors ... ESC using an Arduino and has a couple of posts explaining the concept and demonstrating how it works. His test circuit uses six 2N2222 transistors to ...

At the heart of the circuit is ... output of the motor speed sensor module. Recommended working voltage of the module is 4.5 to 5.5 volt dc. Note that one side of the optical sensor holds s a light ...

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 ... medium power motor drive circuits.
