BLDC Performance Analysis Due to Stator Winding Unbalance

The development of electric motor technology is growing rapidly, so that it requires a motor with high reliability and efficiency, for example, a BLDC motor. The use of a BLDC motor as a driver requires maintenance methods that can maintain the reliability of the BLDC motor. In this final project, performance testing of a BLDC Motor is carried out when there is an unbalanced stator scheme that can be used as a reference for BLDC motor maintenance. This research was conducted by observing the performance detection results of several parameters using software and data loggers. The performance results were analyzed by using the statistical comparison method of each stator against the stator’s performance under normal conditions. Based on the test results, this study provides parameter performance values that have deviations from normal conditions, and the parameter performance values tested are different from the balanced performance when there is an unbalance scheme of the stator winding on the tested BLDC motor.
