A new motor designation was necessary because the Design E motor has higher efficiency, higher locked rotor current and reduced torque requirements compared to existing NEMA motor designs. Design E motors provide increased energy savings that are important to many users, but the possible additional costs of protective and control equipment, as well as more horsepower, must be part of a cost savings calculation. The purpose of this paper is to give users of Design E motors electrical application information concerning the selection of the appropriate motor disconnecting means, motor branch-circuit short-circuit protection, motor circuit conductor, motor controller and motor overload protection, and guidance concerning torque characteristics. This paper describes how motor efficiency is increased and how the design changes related to increased efficiency affect the mechanical and electrical characteristics of motors. This paper reviews the requirements of Article 430 of the 1996 National Electrical Code and provides generic application tables that compare the protection and control requirements of Design E motors with those of Designs B, C, and D.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.

High rates of change of ASD output voltage (dv/dt's), will cause transient currents to flow from motor windings to ground through stray capacitances. Under certain circumstances, these currents can flow through motor or gearbox/machinery bearings, and if large enough in amplitude, lead to reduced bearing life. This paper offers a view, from an industrial environment perspective, of the most common reasons that damaging electrical bearing currents can occur in an ASD-fed motor or in connected machinery, and how installation practices can affect the generation of bearing currents. Technology is discussed that facilitates easy measurements of the common mode current, which can be used to quantify the risk a particular installation may have, as well as offer measurable proof of bearing current reduction after the implementation of corrective measures. Practical suggestions are given to optimize installation practices, which if followed, can reduce or eliminate the major risks of electrical bearing damage.","PeriodicalId":360061,"journal":{"name":"Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat.
