Beginning with this initial installment , and with the gracious permission of ABB/Baldor Electric, we are pleased to announce the beginning of a new series -- Baldor Basics: Motors. This is a collection of basicsdriven, motor-intensive articles authored by former Baldor engineer Edward Cowern, PE, a respected name by many in the electric motor industry. During his tenure at Baldor, Cowern - now enjoying his retirement - was tasked with producing a number of motor- and basics-related tutorials, primarily in response to a steady flow of customer questions regarding motors. Today's customers continue to ask questions and seek answers to address their various motor-related issues. As with Cowern's original introduction to the series, we hope you find these articles useful and would appreciate any comments or thoughts you might have for future improvements, corrections or topics.
A discussion of the basics in DC drives, DC motors, AC drives, AC motors and synchronous motors.
This issue we cover frame sizes and two-speed motors in our continuing series of articles, courtesy of Baldor Electric, dedicated to motor basics.
Part 1: There seems to be a lot of confusion about the voltage standards for motors and why they are structured the way they are. Part 2: The effect of low voltage on electric motors is pretty widely known and understood, but the effect of high voltage on motors is frequently misunderstood.
A good deal of confusion exists regarding the factors that determine an industrial electric bill. The following information is presented to help sort out the various items on which billing is based, and to offer suggestions on measures to help control and reduce electric utility bills.
Fans, blowers and other funny loads are addressend, along with RMS Horsepower loading.
Conservation through lighting alterations using different bulbs, ballasts and light sources is well understood and easy to achieve. The use of improved efficiency three phase induction motors has not been as accepted. There are a number of reasons why conservation efforts with motors have not been as popular.
Amps, Watts, Power Factor and Efficiency; Approximate Load Data from Amperage Readings; Power Factor Correction on Single-Induction Motors.
The final installment in our Baldor Motor Basics series covers 50 Hz requirements, as well as motors wet or damp environments.
Explosion-Proof Motors in Division 2 Areas and DC Drive Fundamentals
Failure to specify the proper motor for use in a hazardous location can have serious consequences - lost production, extensive property damage, and even loss of human life. Selection of the proper motor requires an understanding of Underwriters Laboratories' (UL) and National Electrical Code (NEC) class, group and division designations and the T code letters.
In the process of applying industrial drive products, we occasionally are misled into believing that we are applying horsepower. The real driving force is not horsepower - it is torque. This paper is developed to impart a deeper understanding of torque, its relationship to horsepower, and the types of loads we most frequently encounter.
This issue our Baldor Basics series continues with the topics of motor temperature ratings and metric motors.
A brief overview of the induction motor, including the basics of construction, performance and variable speed drives.
This article summarizes some common hurdles, issues and questions encountered by the newer and casual users of tapered roller bearings.
I need help determining the diametral pitch needed to achieve the closest center-to-center distance for 2 spur gears. The 1st gear is a 34-tooth and the 2nd gear is a 28-tooth. The center-to-center distance between the gears needs to be as close to 2 1/8" as possible.
Mounted ball bearings are everywhere in industrial applications. They serve critical roles in keeping a manufacturing operation running smoothly and in ensuring that equipment functions properly and reliably. So why might it be advisable to spend significantly more for a dimensionally comparable bearing from one supplier versus another?
What are the best methods to adjust tapered roller bearings?
This paper summarizes the chemical, metallurgical and physical aspects of bearing steels and their effect on rolling bearing life and reliability.
When designing a spur-crown pair, is there a formula, guideline or design guide for adapting the spur teeth for the radial angle of the teeth in the crown?
Understanding proper bearing lubrication procedures is critical to ensuring long-term, trouble-free performance. Klüber Lubrication has prepared this explanation as a general guide.
How does one draw and mesh involute gear teeth in AutoCAD?
If youâ™re an electrical engineer you know how an electric motor works; if you arenâ™t, it can be extremely confusing. Therefore, hereâ™s the simplified explanation (or the âœhow an electric motor works for dummiesâ version) of how a four-pole, three-phase AC induction motor works in a car.
In most cases, industrial power transmission calls for flexible rather than rigid couplings in order to forgive minor shaft misalignment. For that reason, this article will focus solely on the selection of flexible couplings.
With today's smaller, hotter - and overloaded - machinery, specifying the correct lubricant is vital.
Everything started in 1800 when Volta developed the first DC battery. Faraday used the DC battery to develop the first electric motor. It used brushes to transfer the battery voltage and current to the rotating disk rotor. This was in mid-1831. Thus was born the brush DC motor.
"Well begun is half done," a quote that most reference materials attribute to Aristotle, certainly applies when selecting mechanical power transmission products. A selection process that is well thought out at the start can ensure that the product selected will be properly sized and appropriate to the application at hand.
A reader asks: I've determined that a stainless steel bearing is the best option for my application. I'm being asked to specify the grade of stainless steel in my product design. I'm not sure which grade to select and specify. Can you help?
There are thousands of sizes and types of standard bearings. In many applications, specifying a standard bearing yields an effective result.
The question is whether or not a customer can save time and money using a step motor. It is followed by another on the differences between brush and brushless motors...
BEARINGS BASICS Q&A: IN CASE YOU DIDNâ™T KNOWâ¦
The 8th International CTI Symposium on Automotive Transmissions, HEV and EV Drives took place in Rochester, Michigan from May 12-15. The event kicked off with its popular introductory seminar "Basics and Practice of Automotive Transmissions."
