Every month, CONTROL’s editors take a specific product area, collect all the latest, significant tools we can find, and present them here to make your job easier. If you know of any tools and resources we didn’t include, send them to wboyes@putman.net, and we’ll add them to the website.

SELECT THE RIGHT ELECTRIC MOTOR

Confirmat
 0031/492-558230   www.specAmotor.com

SpecAmotor is a service where engineers can determine the best electric motor for their drive application. It is brand-independent. The SpecAmotor database contains over 6,000 browsable motor configurations. Via a list of brands, all electric motors can be reached. On the motor page, a datasheet of the motor and an overview with all the transmissions that can be applied with the motor are provided. When the transmission is selected, the torque-speed-curve is shown for that transmission with the already selected electric motor.

POWER QUALITY

Power Standards Lab
510/522-4400   www.powerstandards.com/tutor.htm

Website contains tutorials and standards for the power quality industry. There is a fun simulator for engineers who want to get an intuitive feel for power quality issues. There is also a power quality video that is an introduction to voltage Dips/Sags. There is a list of IEEE power quality standards, IEC power quality standards, utility power quality power standards, other industry-specific power quality standards and more.

FREQUENCY CONVERTERS

Danfoss Drive

Downloadable book, Facts Worth Knowing about Frequency Converters, has chapters on 3-phase AC motors, frequency converters, frequency converters and motors, protection and safety, general mechanical theory, general AC theory and more.

UNDERSTANDING MOTORS/DRIVES

ISA
919/549-8411   www.isa.org

This course gives you a broad perspective of DC motors, AC motors (single and three-phase) and variable speed drives (for AC induction motors and DC motors). Industrial applications of variable speed drives for constant torque, constant horsepower and torque/variable horsepower are included. Also covered are motor starter circuits and reduced voltage starting techniques. Stepper motors and servo motors are discussed with their advantages and applications. 

LINEAR DRIVE SELECTION

Amacoil
610/485-8300   www.amacoil.com

UHF software program analyzes linear motion application requirements and assures the correct size Uhing rolling ring drive. Application data may be submitted by telephone or using forms on the Amacoil web site. The program determines side thrust requirements, selects the correct size Uhing linear drive and provides other useful technical specifications and diagrams.

POWER QUALITY

Copper Development Association
