Note:
1. CPR to LPI Conversion. CPR range is typical value for a 1-inch outer diameter (OD) codewheel.
2. Shaft size. Typically 2 – 8mm for 1-inch OD codewheel. Larger shaft sizes possible if used with a larger OD codewheel.
3. Maximum RPM value is based on response frequency limitation of the encoder signal. Mechanical limit may be higher.
4. Motor Diameter is suggested minimum OD of a motor that the encoder series can t into.
5. AEAT-60xx – magnetic encoder
5.6 Encoders for BLDC Motor System:
By Motor Diameter
Electrical motors are used in a diverse range of applications
stretching from industrial usage, medical equipments
oce automation to consumer products. Taking this into
consideration, the motor system itself is oered in a variety
of sizes depending on the usage, capacity , etc.
Here, Avago’s encoders are developed to meet dierent
motor diameter sizes. The encoders are suitable for motors
that measure from 10mm to 56mm in diameter, or larger.
