Overview
This is a three-hour course about a relatively new form of single-phase induction motor known as the Written-Pole® Motor. The motor was developed by Precise Power Corporation and it uses an innovative approach of controlling the magnetic field of the motor to reduce the starting current requirements. The result is a motor that has starting current requirements of only about twice the normal running current and, as an added benefit the motor has an efficiency of 90% or better. The Written-Pole® motor has been developed with inherently low per-unit starting current and they can be applied in single-phase service areas to ratings of over 100 hp without exceeding the starting current limits of many utility systems.
For PDH credit, the course includes a multiple-choice quiz consisting of twenty (20) questions.
