  • Low-Cost DC Motor Speed Control with CMOS ICs
    by the TC4469. Two low-cost CMOS ICs manage a 12 VDC, current-limited speed. In the lower rail devices, a small series resistor helps prevent gate. control circuit for DC brush motors. The circuit design (see. oscillation and slows transition time, helping the upper device to. Figure 1) uses PWM (pulse width...
  • Torque motors do the trick
    and accurate positioning. Application calls for low-cost method of producing. rotation. Motor air gap cannot be protected against contaminants. Application lacks servocontrol. An important difference between direct-drive systems and those driven by conventional dc servomotors and gearboxes is that torque...
  • Intelligent Remote Positioner
    The excellent cost/performance ratio of the PIC16C5X makes it well suited as a low-cost proportional D.C. actuator controller. This application note depicts a design for a remote intelligent positioning system using a D.C. motor (up to 1/3 hp) run from 12V to 24V. The position accuracy is one...
  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    Pulse Width Modulation (PWM) fan speed control methodology pulse-width modulates a fan's full-rated power supply voltage at a low frequency, typically 30 Hz. A typical PWM circuit, consisting of a transistor in series with a fan, can be small and inexpensive because it is either fully...

  • Taking the roar out of the crowd: Hybrid Motorcycles
    to less than 50% for traditional windings. This results in super-low resistance and high current capacity. Unlike other brushless motors, the SolidSlot operates at low voltages (12 to 36 Vdc) and current up to 450 A. Performance comparable to brush-dc motors can come with as little as one-third...
