Fundamentals of motor control - STMicroelectronics
www.st.com• The motor is controlled applying a voltage on the motor leads. The higher the voltage, the higher the speed. The direction is changed reversing the polarity on the leads. • The maximum torqueis limited by the current rating of the motor and it is obtained at zero speed (start-up).

THE FUNDAMENTALS OF AC ELECTRIC INDUCTION MOTOR …
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.
MEDIUM VOLTAGE MOTOR ACCEPTANCE TESTING
www.tmeic.comMEDIUM 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,
