  • Low-Cost DC Motor Speed Control with CMOS ICs
    Two low-cost CMOS ICs manage a 12 VDC, current-limited speed control circuit for DC brush motors. The circuit design (see Figure 1) uses PWM (pulse width modulation) to chop the effective input voltage to the motor. Use of CMOS devices gives the benefits of low power, minimal heat and improved

  • Electrical Considerations of Fan Cooling
    . The standard fan supplied with the amplifiers is a 12V brushless DC motor fan. Like all switching circuits the brushless motor commutation generates electrical noise. If care is not taken in how the fan is connected to the amplifier circuit some of that electrical noise may appear at the output
  • Software PID Control of an Inverted Pendulum Using the PIC16F684
    of three main parts: the base platform, the pendulum and the controller board. The base platform is a 3-point platform, 2 wheels (one of which is geared and attached to a DC motor) and an audio jack. When the DC motor is turned on, the base platform will rotate around in a circle with the center
