For years, electric motor repair facilities have been routinely rewinding the common three-phase electric motor. With the complexity of some of the newer technologies, the chance for error is signifcantly increased. We have had to become more observant and heighten our awareness. Here are a couple of examples that one service center encountered, and where we were able to identify the data and rewind the motor successfully.
