Scope of Test Method 1 for Synchronous Motors without DC Excitation Windings: This standard specifies the test requirements and methods for synchronous motors without DC excitation winding. This standard applies to the testing methods for synchronous motors without DC excitation winding, such as permanent magnet synchronization, hysteresis synchronization, and reluctance synchronization (excluding electromagnetic deceleration permanent magnet synchronous motors). The following synchronous motors without DC excitation winding are referred to as motors in this standard. 2 Normative References: The clauses in the following documents become clauses of this standard through reference in this standard. For dated reference documents, all subsequent amendments (excluding corrected content) or revisions are not applicable to this standard. However, parties to agreements based on this standard are encouraged to study whether the latest versions of these documents can be used.
