Servomotor Technology Overview
Servomotors are divided into two types: DC servomotors and AC servomotors.
DC servomotors are driven by direct current (DC). They have a long history. Up until the 1980s, the term "servomotor" used to imply a DC servomotor.
From 1984, AC servomotors were emerging as a result of rapid progress in microprocessor technology. Driven by alternating current (AC), AC servomotors are now widely used because of the following advantages:
- Easy maintenance: No brush
- High speed: No limitation in rectification rate
Note however that servomotors and Servopacks use some parts that are subject to mechanical wear or aging. For preventive maintenance, inspect and replace parts at regular intervals.
Scientific Information and Studies
The boundaries of each SGMA reflect the biological and geographical realities of area currently occupied by a population or populations of sage-grouse. The SGMAs are based upon the location of occupied leks, the identification of nesting and brood rearing habitat, on average, within a 3.0 mile radius of the occupied leks, and associated winter and other habitat.
For decades prior to the current review, the DWR has been supporting research and community-based conservation efforts to learn more about the ecology of the species. To facilitate this effort, the DWR established ten Local Area Working Groups (LAWGs) under the general direction of Utah State University, with the first established as far back as 1996.
Because of this early and ongoing assessment, the State of Utah is fortunate to have a high level of knowledge about seasonal range, migration routes, and other factors known to be essential to maintenance of the species, all in the context of Utah's unique conditions.
In Utah, based on statewide averages, 91% of greater sage-grouse hens nest within 3 miles of a lek. This is based upon data compiled by the DWR, Utah State University and Brigham Young University. These data include 478 sage grouse nests within SGMAs.
