Motors

Synchronous AC Motor

  • Stator produces a constant magnetic field that powers the rotor
  • Once accelerated, the motor produces a constant torque

Asynchronous AC / Induction

  • The stator produces a magnetic field which powers the rotor
  • Magnetic polarization in the stator change the motors torque

Brushed DC motor

  • Inside the stator, brushes apply electric current to a rotating set of magnets that in turn power the rotor
  • Were the first commercially applied electric motor
  • Types: Grouped by their RPM

Brushed DC Geared Motors

  • Improvement of the DC motor that comes with a set of intertwined gears to provide better torque and reduced speed
  • Types: Grouped by RPM

Brushless DC motor / Synchronous DC motor

  • Provide an alternating magnetic field inside the stator that power the rotor
  • Types

Brushless DC stepper motor

  • Provide an alternating magnetic field inside the stator that power the rotor, and divides the rotation into discrete steps
  • Types: Unipolar, Bipolar

Brushless DC Servo Motors

  • A special Brushless Motor that provides fine grained control of the rotor via an analogous or digital signal
  • Types: Nano, Micro, Slim Wing etc.

Sensors

Light

  • Photo resistor converts light intensity to electric resistance
  • Photovoltaic Cells convert solar radiation into electric current

Proximity

  • Infra Red Transceivers emit infra-red light and measure the light reflection
  • Ultrasonic sensors emit sound and measure the echo impulse
  • Laser emit lasers and measure the lasers reflection

Sound

  • Microphone

Images

  • Camera

Movements and Acceleration

  • Provided via motors and their controllers
  • Gyroscope

Environment

  • Temperature
  • Humidity
  • Smoke
