1 Baldor Basics: Motors (December 2016)

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.

2 Baldor Basics: Motors (February 2017)

This issue we cover frame sizes and two-speed motors in our continuing series of articles, courtesy of Baldor Electric, dedicated to motor basics.

3 Drive and Motor Basics (October 2013)

A discussion of the basics in DC drives, DC motors, AC drives, AC motors and synchronous motors.

4 Baldor Basics: Motors (March 2017)

This issue our Baldor Basics series continues with the topics of motor temperature ratings and metric motors.

5 Baldor Basics: Understanding Torque (April 2017)

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.

6 The Workhorse of Industry: The Induction Motor (December 2013)

A brief overview of the induction motor, including the basics of construction, performance and variable speed drives.

7 Choosing the Right Grade - Specifying Stainless Bearing Steel (August 2014)

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?

8 Determining Diametral Pitch, Center Distance (October 2016)

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.

9 How Does An Electric Motor Work (October 2016)

If you’re an electrical engineer you know how an electric motor works; if you aren’t, it can be extremely confusing. Therefore, here’s the simplified explanation (or the “how an electric motor works for dummies” version) of how a four-pole, three-phase AC induction motor works in a car.

10 Trends in Industrial Gear Oils (April 2013)

With today's smaller, hotter - and overloaded - machinery, specifying the correct lubricant is vital.

11 Critical Factors for Proper Product Selection and Sizing (August 2014)

"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.

12 Working in AutoCAD (April 2014)

How does one draw and mesh involute gear teeth in AutoCAD?

13 Rolling Bearing Steels - A Technical and Historical Perspective - Part 1 (February 2013)

This paper summarizes the chemical, metallurgical and physical aspects of bearing steels and their effect on rolling bearing life and reliability.

14 Sorting Out Flexible Couplings (August 2012)

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.

15 How to Design a Spur-Crown Gear Set (October 2013)

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?

16 Brush DC Motor Runs Along (August 2013)

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.

17 Should You Pay a Premium for a Mounted Ball Bearing (December 2013)

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?

18 Adjusting Tapered Roller Bearings (June 2014)

What are the best methods to adjust tapered roller bearings?

19 Tapered Roller Bearing Application Guide (June 2014)

This article summarizes some common hurdles, issues and questions encountered by the newer and casual users of tapered roller bearings.

20 Beyond Bearings Basics (October 2015)

There are thousands of sizes and types of standard bearings. In many applications, specifying a standard bearing yields an effective result.

21 Oriental Motor Fair Covers Much More than the Basics (June 2008)

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...
