MEDIUM VOLTAGE MOTOR ACCEPTANCE TESTING
MEDIUM VOLTAGE MOTOR ACCEPTANCE TESTING Medium voltage motors have been very well understood and studied for more than a century. While manufacturing, assembling, and testing of a motor appear simple, the reality is quite the opposite. Oftentimes, acceptance testing of motors is specified; however, the terminology used in testing by vendors,

www.enginuitysystems.com208-230/460 V motor will have degraded performance at 208 V. Another common misconception is to request a motor rated at network voltage, for example, at 480 V. The NEMA standard is 460 V. The voltage rating assumes that there is voltage drop from the network to the motor terminals. Thus, the 460 V motor is appropriate on a 480 V network.
