C. Electric Motor Davenport Rotary Motor Stepper Motor/Servo Motor
  1. The planned sequence of contemporary inventions – (A) the Relay/Motor Control Sequence, (B) the Electronic Amplifier Sequence, and (C) the Electric Motor Sequence – are at the heart of industrial automation. A 3D printer consists of microcontrollers, amplifiers, and stepper motors. An understanding of the science and engineering principles that underlie early inventions provides scaffolding for understanding the modern technologies that followed
