All Rights Reserved  \n1.0 Introduction  \nSpeed and Torque Regulation  \nAdjusting and regulating the operating speed of a driven machine is usually the primary reason for using any adjustable speed drive. This technical guide explains the relationship between speed and torque and discusses various aspects of speed and torque regulation.  \nUsing This Guide  \nThis guide has been designed to provide an understanding of the principles of speed and torque regulation as they relate to high performance adjustable speed drives. The background discussion leads to information regarding applying adjustable speed drives in high performance applications.  \nReaders wanting to gain an understanding of the principles of speed and torque regulation should start at Section 2,(page 2).  \nFor information regarding high performance applications, please go straight to Section 7 (page 9) .  \n1  \n2.0 Adjustable Speed Drive Terminology  \nThe terminology used in discussing adjustable speed drives is not always used clearly and consistently. This guide attempts to clearly define the essential terms using the definitions that appear to be most commonly recognized in the United States.  \nIn this guide, the term Adjustable Speed Drive means the combination of an Adjustable Speed Motor Controller and a motor. The adjustable speed motor controller provides electrical power that is controlled in a way that regulates the operation of the motor. The motor converts the electrical power to mechanical power in the form of speed and torque.  \nIt is important to remember that many of the characteristics ofa drive are the result of a particular motor and a particular controller working together as a coordinated system. The drive will not provide the expected performance unless both the motor and the controller have the necessary characteristics and capabilities. An Adjustable Frequency Drive or AF Drive combines an AC motor with an Adjustable Frequency Controller that regulates the frequency of the AC power applied to the motor. In addition to regulating the frequency, the AF controller regulates the voltage and other characteristics of the power.  \nA DC Drive combines a DC motor with a DC Controller or Converter that regulates the DC voltage and current applied to the motor armature and shunt field.  \n2  \n3.0 Speed, Torque and Horsepower  \nSpeed and torque are the fundamental quantities used to describe the operation of rotating machinery. Speed is usually expressed in shaft revolutions per minute or RPM. In adjustable speed drive applications, performance is usually discussed in terms of the speed, torque and other parameters that apply to the shaft of the motor. If performance parameters are defined for some location other than the shaft of the motor, it is usually necessary to determine equivalent parameter values as they apply to the motor shaft. Process or machine quantities such as surface feet per minute must be converted to the equivalent motor shaft RPM. To distinguish the location at which a parameter such as speed is measured it is sometimes written as“speed at the motor shaft” or “speed referred to motor shaft.”  \nTorque is an expression of the force applied to turn a shaft. In Figure 1, a force of 25 pounds is being exerted on the crank. The torque is the force multiplied by the radius of the crank or 50 Pounds-Feet. Pounds-Feet or Lbs.-Ft. are the usual units of measurement for","cbCaimBIfnTggP3T","https://ap.wps.com/l/cbCaimBIfnTggP3T","pdf",313550,28,"English","# 1.
