Optical encoders use an LED on one side of the code disc and a photodiode or optical phased array detector on the other side (see Figure 1). As the motor shaft turns, the patterned disc modulates the beam. Linear encoders operate analogously.

WebA 40000 RPM vector-controlled induction motor drive is introduced. In a previous paper by T. Kume et al. (see Proc. IPEC 1990 conf., Tokyo, p.1132-1136, 1990), conventional vector control with a shaft encoder was employed in a low-speed range, while constant V/f (volt-per-hertz) PWM control was employed in a high-speed range.
