DUAL DC-MOTOR POSITIONING SYSTEM

STMicroelectronics 

L6515

POSITION ENCODER

Main advantage of the operation principle of the

positioning system is that a high performance po-

sition encoder is not required.

The system accepts several phases and ampli-

tude errors of the encoder output signal without

affecting the system performance.

Two position sensors are useful.

1) Optical-Encoder with IR-LED and Phototransistor

Figure 1.

2) Magnetic Encoder with hall-effect sensors

Figure 2.

The allowed spread of the encoder output signal refer to reference level is shown in Fig.3.
