摘要：Brushless reluctance motors are compatible with energization by the simple rectilinear voltages easily produced by motor control circuits having a small number of mechanical or solid state switches. These motors with two or three opposing pairs of main and feedback stator windings, and suitable ...
Step 2: Control DC Motor Using Transistor Easy way to control DC motor is to use transistor and arduino board. Transistor in this case is used as a switch. For this you will need any NPN transistor. I am using 2N2222 transistor. Every transistor has a Base (B), emitter (E) and coll...
