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 ...

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 ...

The motor-speed-control circuit in the figure shows an SG3524 pulse-width-modulation (PWM) IC, U2, ... Low-Cost Circuit Controls PM DC-Motor Speed. Sept. 29, 2003.

Motors are not overly complex, but this one is downright simple. Carl Bujega has been working on a motor design that heavily relies on the capabilities of the printed circuit board (PCB) fabricatio… ...

In this engaging DIY tutorial, you'll discover how to make a simple DC motor from scratch. Perfect for beginners and ...

18 to 40 (within one second) Power supply voltage 2 VCC Vcc (V) -0.3 to 6 Ambient temperature Ta (°C) -40 to 125 ... Automotive Brushed DC Motor Control Circuit Using TB9103FTG.

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was po… ...

When energy-efficiency costs come into play, more designers are opting for the electronically commutated motor rather than familiar AC and DC versions. For motor applications, engineers have ...
