DC Servomotor and AC Servomotor

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. For details, refer to Chapter 6 Inspection, Maintenance, and Troubleshooting.

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 leks2, and associated winter and other habitat.

For decades prior to the current review, the DWR has been supporting research and communitybased conservation efforts to learn more about the ecology of the species. Appendix 8 contains a listing of research studies and reports on sage-grouse conducted in Utah. 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. These LAWGs were composed of private interests and governmental entities, and were charged to assess the local nature and scope of the threats to the species, and to recommend a course of action to address those threats.

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. This information, along with peer-reviewed scientific studies, forms the basis for this plan.

When local or county, state agency, and federal agency planning is aggregated into a statewide plan for sage-grouse, the collective result provides a complete and credible means of addressing the factors used by the FWS to measure the success of conservation efforts. Specifically, the objectives to enhance and increase habitat, and the implementation of this Plan to eliminate threats to greater sage-grouse populations will address the need for resiliency of the species – the ability of birds to persist in each management area in the face of normal or catastrophic events, and provide adequate representation of the species across its range in Utah. This plan further protects against the need for this species to be listed as threatened or endangered by providing a level of redundancy - numerous resilient populations that contribute to the long-term viability of the species across its range.

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. The Strawberry SGMA is excluded from this analysis due to the transplanted nature of the population and the on-going establishment of new leks.
