  • Avoiding Resonance with Stepper Motors
    Stepper motors are electrical brushless motors, usually with a high number of poles. They are typically used as an easy and cost-effective positioning solution, as they can be driven step by step without needing a rotor position feedback system (such as an encoder or integrated hall sensor
  • Using the PIC18F2431 for Sensorless BLDC Motor Control
    also discussed the use of PIC18FXX31 devices to control a BLDC motor in both open loop and in closed loop using Hall effect sensors and quadrature encoders. This applications note describes BLDC motor speed control without the use of sensors.
  • Sensorless BLDC Control with Back-EMF Filtering Using a Majority Function
    a 3-phase motor has to be used. The motor if the rotor runs immersed in fluid, it is desirable to run control algorithm described here has six main parts: the motor without position sensors, which is commonly * Sampling trapezoidal BEMF signals using the known as sensorless operation. dsPIC Analog
