[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future… ...

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

In addition, the circuit can easily stop the motor if you program a 0-Hz output frequency. Figure 3 shows the complete system. The most significant bit of the on-chip DAC switches to the V OUT pin of ...

With this circuit, you can use low-torque, low-revolutions-per-minute stepper motors in systems in which you formerly needed dc gearbox motors. By changing the pushbutton to a dpdt switch, you can ...

A typical 3-wire control circuit is shown in Fig. 2 (click here to see Fig. 2). It consists of a normally closed stop button (STOP), a normally open start button (START), a sealing contact (M), and ...

In principle, an electric motor circuit is a series of simple and complex resistance, inductance, and resulting phase angles that are each 120° apart in a 3-phase system (Fig. 1 above). When original ...

A 50% duty cycle motor with a 30 min run time means the motor can operate at its rated output for 30 min. Then it must stay off at least 30 min — for 60 min total time — before running again.
