  • Motor Control Sensor Feedback Circuits
    Sensors are a critical component in a motor control system. They are used to sense the current, position, speed and direction of the rotating motor. Recent advancements in sensor technology have improved the accuracy and reliability of sensors, while reducing the cost. Many sensors are now
  • Brushless DC Motor Control Made Easy
    This application note discusses the steps of developing several controllers for brushless motors. We cover sensored, sensorless, open loop, and closed loop design. There is even a controller with independent voltage and speed controls so you can discover your motor's characteristic's empirically.
  • Industrial Roller Door DC Motor Solution
    Power Motor designed a PMDC gearbox motor-PGM.W072M0078 for the electric garage door which equipped with worm and helical gear. It outputs low speed and high torque to control the up and down movement of the rolling gate. The Hall sensor is installed inside the motor to provide rototion and speed
  • DC Gearbox Motor For Garage Door Industry Automation
    Power Motor designed a PMDC gearbox motor-PGM.W072M0078 for the electric garage door which equipped with worm and helical gear. It outputs low speed and high torque to control the up and down movement of the rolling gate. The Hall sensor is installed inside the motor to provide rototion and speed
  • 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 Field Oriented Control of PMSM Motors using dsPIC30F or dsPIC33F Digital Signal Controllers
    FOC technique also overcomes restrictions placed on some applications INTRODUCTION that cannot deploy position or speed sensors because the motor is flooded, or because of wire harness place- Designers can expect environmental demands to con- ment constraints. With a constant rotor magnetic field
  • Using the dsPIC30F & dsPIC33F DSCs for Sensorless BLDC Control
    braking current to regulate DC bus The BLDC motor is usually operated with one or more voltage. rotor position sensors since the electrical excitation Commutation scheme allows up to 30° phase must be synchronous to the rotor position. For reasons advance to be linearly introduced as the speed of cost
  • Integrated Wheel Drives Lower Cost of Mobile Robot Ownership
    products. Leveraging its design expertise, ElectroCraft has addressed the complexities of mobile robot drivetrain design with the introduction of its MobilePower TM Wheel-Drive (MPW) integrated mobile robot wheel drives. The MPW52 and larger MPW86 feature high torque-density brushless DC motors
