ANGULAR PLACEMENT

POSITIONING: HALL SENSOR A AND B

This will tell the RPM speed. Often

400 pulses/ rev

• A and B pulses are offset by 90°.

This offers rotational direction

of motor. That is, “A” lead edge

is leading “B”, thus indicates CW

direction. When “A” leads “B”,

then CCW.

• Some encoders (not this one)

have another sensor output (i.e.

C) labeled “Home Position” which

offers one pulse per revolution.

• Some encoders have serial

interface and calculates RPM and

periodically sends various

parameters. 12
