Baldor BC142 - Electrical Ratings; General Performance Specifications

Notes: 1. Step-down operation: motor may have reduced brush life. 2. Performance is for SCR rated permanent magnet motors only. Lower performance can be
expected with other motor types. Factory setting is for 3% load regulation. To obtain superior regulation, see Section 11.6, on page 27.
