IEEE 113 1985 Edition, January 1, 1985 GUIDE: TEST PROCEDURES FOR DIRECT-CURRENT MACHINES
More info
Description / Abstract:
These test procedures include recommendations for conducting and
reporting generally acceptable tests to determine the performance
characteristics of conventional direct-current machines. The tests
are in two categories as described in 1.1 and 1.2.
Tests of Direct-Current Motors and Generators Designed for Essentially Ripple-Free Operation. For operation to be classed as ripplefree in accordance with this test procedure, the peak-to-peak value of the alternating component of the current shall be less than 6%, or the rms value less than 2%) of the rated current of the test machine at any of the test conditions provided that the lowest alternating frequency component of the current is 50 Hz or greater.
Tests of Direct-Current Motors Designed for Use with Rectifier Power Supplies. When a test procedure applies to a dc motor supplied with rectified power not meeting the essentially ripple-free criteria of 1.1, the procedure will be identified by the following opening statement: "On rectified power .
A brief bibliography of technical papers relating to the operation of dc motors on rectified power is located in Section 8.
Other Test Procedures. It is recognized that there may be test procedures other than those described herein. When more than one procedure can be used, local conditions and the degree of precision desired will determine the procedure to be used. This guide shali not be interpreted or construed as requiring the performance of any or all of the tests herein, in any given transaction.
