Incremental shaft encoder
Incremental shaft encoder
The shaft encoder is used to convert rotary motion into electrical pulses. The pulses sent from the encoder’s output are analyzed by appropriate electronic circuits.
Applications:
Some applications of the shaft encoder include:
The shaft encoder can be used in various applications, such as determining the shaft position (in terms of angle), determining the direction of rotation, and more.
Shaft Encoder Connections:
The shaft encoders produced by TabrizPeguh are of the incremental type, generating a specific number of pulses per revolution at the output.
Number of Outputs:
The shaft encoder has three outputs as follows:
Output B has a 90-degree electrical phase difference relative to Output A and can be used for the following purposes:
Determining the Direction of Rotation
Using outputs A and B, the direction of rotation can be detected with the help of a flip-flop circuit.
Quadrupling the Number of Pulses per Revolution
This is achieved using an electronic circuit.
Note: The pulse width (t) must be designed such that at the maximum rotational speed, the pulses do not overlap.
