2 Motor Management Best Practices Part 3 (February 2016)

This three-part series on motor management best practices focuses on the importance of instituting a motor management plan as a necessity in effectively administering the electric motors in a facility. The goal of a motor management plan is to take advantage of opportunities for energy savings and increased productivity using energy efficient, reliable motors such as NEMA Premium efficiency motors, herein referred to as “premium efficiency” motors.

3 The Test Run (March 2016)

Modeling and simulation is a key driver of innovation. Whether it’s general manufacturing, consumer goods or life sciences, the ability to realistically model and simulate the response of parts, sub-systems and complete assemblies to increase accuracy and repeatability is vital in today’s analytical world.

4 Effect of Assembly Errors in Back-to-Back Gear Efficiency Testing (December 2015)

As gear efficiency is improved in small steps, it is important to be able to distinguish actual improvements from scatter that can occur while testing. An FZG back-to-back gear test rig was used to investigate how the assembly and re-assembly of the same test setup affects the measurements. A spread in torque loss between one assembly and another of the same test setup were observed. Rig conditions also affected the spread in input torque. With knowledge of how the spread in torque loss varies due to assembly, test results could be distinguished between changes due to assembly and actual differences between tests.

5 Motor Management - Best Practices (October 2015)

Reducing losses and increasing profits by instituting a motor management plan is what this series of articles is all about. Here in Part I, we discuss how to create a motor inventory and establish repair-or-replace motor guidelines. Subsequent topics in this three-part series will address (Part II) motor failure policies and purchasing specifications, and (Part III) repair specifications and preventive and predictive maintenance, respectively.

6 Setting Techniques for Tapered Roller Bearings (September 2015)

Tapered roller bearings can be set at initial machine assembly to any desired axial or radial clearance. This unique feature enables a designer to control bearings to meet anticipated application operating conditions, and thereby provide optimum bearing and system performance.

7 Copper in Motor Repair Facilities (March 2017)

Three electric motor repair facilities share best practices for utilizing copper in motor repair, and recommending new motors to replace older, less-efficient motors

8 Motor Management - Best Practices (December 2015)

Energy costs and downtime can be greatly reduced by instituting a motor management plan. Part II of this three-part series specifically addresses the establishment of a motor failure policy and the development of purchasing specifications. Part I addressed the general aspects of a motor management plan, including the first steps of creating a motor inventory and guidelines for motor repair and replacement. Part III will examine motor repair specifications as well as preventive and predictive maintenance.

10 The Green Spin: Baldor Redefines Cooling Tower Performance (February 2011)

The Baldor Reliance RPM AC Cooling Tower Direct Drive Motor is designed exclusively for the cooling tower industry. This motor combines the technologies of the power-dense, laminated frame RPM AC motor with high performance, permanent magnet salient pole rotor designs.

11 Minimum Design Speed Considerations for Sleevoil Bearings for Industrial Fan Applications (September 2016)

Slow speed operation of fan systems within the air handling industry is generally performed due to two reasons: a coast down operation is required for hot (induced draft) fans to cool down before shutdown (often by using a turning gear), and operational efficiency improvements can be achieved during non-peak periods by slow speed operation using a VFD. In either case, when these fans are supported by hydrodynamic bearings, it is the oil film thickness developed from the bearing-shaft interaction that limits the minimum speed that can be maintained without causing premature wear and bearing failure. This paper will present a brief overview of lubrication theory and critical design parameters to achieve slow speed operation.
