Technical Information Appendix D This appendix provides general information that will help you better understand how this equipment works. Understanding Overloads Purpose and Scope The information below has been collected to help you understand the role of an overload, how an overload works, and how to calculate the overload setting to protect the motor. The Importance of Protecting Your Motor The following statement describes the importance of protecting electric motors and is a good illustration of why we need overloads.

Jack Table™ Platen Press What is an Overload? So, what is an overload? The term literally means that too much load (what the motor is driving) has been placed on the motor. A motor is designed to run at a certain speed, called its synchronous speed.

Page 118 Jack Table™ Platen Press • A design that meets the special protective needs of motor control circuits • Allow harmless temporary overloads, such as motor starting, without disrupting the circuit • Will trip and open a circuit if current is high enough to cause motor damage over a period of time •...
Page 119 Class 30 has a longer time delay to be used on high inertia loads that require a long acceleration or have shock loading that causes repetitive motor inrush. The overload class that MiTek normally specifies for equipment is a Class 10. Since it is possible to burn out a motor in less than 20 seconds, we have chosen to protect the motor with the highest degree of protection.
Page 120: Codes And Standards
Jack Table™ Platen Press Codes And Standards NFPA 79—Electrical Standard for Industrial Machinery, 2002 7.3.1.1 Motors. Motor overload protection shall be provided to each motor in accordance with Article 430, Part III, of NFPA 70, National Electrical Code. NEC 2002—National Electrical Code 430.32 (A) (1) Separate Overload Device.
Page 121 Jack Table™ Platen Press Example 3 40 hp, 208V, 3 phase, wound rotor motor, FLA 118 amps. Overload Protection = 118 amps times 115%=136 amps The motor overloads must be calculated using the nameplate current and not from Tables 430-148 or 430-150 of the National Electrical Code.

Jack Table™ Platen Press Glossary of Overload Terms Full Load Amps (FLA) This is the current flow required by a motor during normal operation under normal loading to produce its designated horsepower. Motors having nothing attached to their shaft will draw less than the FLA current.
Page 123 Jack Table™ Platen Press motor load. The motor load “seen” by a motor is dependant upon how the load is connected to the motor, the dimensions of the load, and the weight of the load. A load connected to a motor by a gearbox reduces the load by the square of the gear ratio.
Page 124 Jack Table™ Platen Press NEMA Design Ratings NEMA ratings refer to the torque ratings. The following ratings apply to motors: NEMA B The NEMA B motor’s percentage of slip ranges from 2 to 4%. It has medium values for starting or locked rotor torque, and a high value of breakdown torque.
Page 125 Jack Table™ Platen Press Class 20, and Class 30. Class 10, for example, has to trip the motor off-line in 10 seconds or less at 600% of the full load amps. This is usually sufficient time for the motor to reach full speed.
