In module 3 you will learn principles of DC motors, traditional brushed motors, as well as electronically driven brushless motors. We will discuss shunt wound, series wound, compound wound, servo, ...

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...

Second, when you cut the power, the motor continues to rotate for a certain time, depending on its initial speed and inertia. The circuit in Figure 1 can be useful for designs that don't need precise ...

EW Technology 25/02/2004 – Embedded exhibition sets out to simplify DC motor control circuits Embedded exhibition sets out to simplify DC motor control circuits Richard Wilson Simplifying the design ...

The trick, apparently, is to measure the internal dc resistance of the motor – ether with an ohm meter, or though applying a low voltage to the motor, stalling it, then measuring the current. Add a ...

E-2's main propulsion system consists of two DC motors directly driving contra-rotating propellers. An underwater vehicle with a single propeller is subject to undesirable torque forces, especially if ...
