Feedback control

In many cases, industrial equipment might use motor as a component. In this case, encoder will be used to determine precise driving current by monitoring on-going motor operation/status.
Encoder will allow to measure the rotation speed, the location and the direction of the rotation. Based on this information, accurate driving current etc. for precise operation parameter can be calculated.

Optical encoder

Reflective Optical Encoder

Encoder can be the key component for servo motor control.
Seiko NPC has a optical encoder lineup such as SMD-01B、SMD-04B、SME-08A、SME-08B、SM3414B etc.
