Technical Theory

Mechanical degree is the actual rotation of the shaft in degrees. Electrical degree is used for electrical signals. The required time for completing one alternating voltage/current cycle is defined as 360 electrical degrees (el°). For incremental encoders, one cycle is equal to one complete pulse. With a given PPR the electrical degree can be converted to mechanical degree for any incremental encoder.

Every 90 el° the incremental encoder outputs a rising or falling edge on the “A” or “B” output that can be interpreted as a count. If an encoder outputs 1000 PPR, a counter can interpret 4000 counts (4 counts each pulse).

The phase angle states the length between 2 edges, given in el°. This parameter is typically specified with a defined constant phase angle value and phase angle error (also called quadrature error).

 

Package

Each single encoder is packed into a single safe carton with protecting bubble.

Then all encoders will be put into a bigger carton to prepare shipment.

About Encoder Vibration

Vibration acting on an encoder always cause wrong pulse easily.

So we have to pay more attention to encoder working place.

The more pulse per round, the narrower groovy spacing of grating, ore effect to encoder by vibration, when motor speed is low or even stopped, vibration acting on encoder shaft or encoder shell would cause grating vibration, in this way, encoder might show wrong pulse signal.
