  • Dc motor impersonators
    limits, the torque of a dc motor is a linear function of input current. So it is relatively easy to get solid performance out of a dc motor with standard proportionalintegralderivative (PID) controllers. In reality, the type of motor that works best in any given application depends on many other system...
  • Brushless DC (BLDC) Motor Fundamentals
    for commutation; instead, they are electronically commutated. BLDC motors have many advantages over brushed DC motors and induction motors. In addition, the ratio of torque delivered to the size of the motor is higher, making it useful in applications where space and weight are critical factors...

  • AVR360: Step Motor Controller
    of the controller. Theory of Operation. A DC step motor translates current pulses into motor rotation. A typical motor contains. four winding coils. The coils are often labeled red, yellow/white, red/white and yellow,. but may have other colors. Applying voltage to these coils forces the motor to step one. step...

    . TC9400. Tachometer. F/V. (Optical or. Magnetic). FIGURE 3: Motor speed control. PROPORTIONAL FLOW-RATE CONTROLLER. A TC9400 F/V converter can be used to regulate the amount of liquid or gas flowing through a pipeline. The flow-rate detector generates. a pulse train whose frequency is proportional...
  • Mathematics of Electronic Motor Control
    brush motor, which is a single phase device, generating this is done by a mechanical commutator with brushes. In a brushless DC motor, it must be done by the external controller. Figure 1 shows two kinds of force that are generated by the magnetic field interactions. They are known as the Q (quadrature...
