Let’s be real: electricity is expensive and the tolerance for waste these days is low. Efficiency standards have tightened, even with motors accounting for a significant share of global electrical use. Estimates from CLASP show that motor-driven systems represent about 30 percent of total worldwide electricity consumption. With that scale […]

Every OEM wants machinery that runs faster and lasts longer. Achieving that level of performance begins with one core decision: the motor. Servo motor optimization defines how efficiently motion is controlled. It impacts how compact a system can be built and how reliable it will perform within modern motion control […]

After many years of working with various motor manufacturers, it is still surprising that so few customers understand the UL process. And for many of us, including our customers, it is not what we might have thought we were getting. I have known several people to use laboratories such as […]

TruTech Servo Motors & Systems This presentation will discuss the design issues of designing a permanent magnet motor to be used in low voltage applications. The major issue in these applications is the low inductance of these motors and the high currents required. This presentation will talk about these issues […]

TruTech Servo Motors & Systems Electric motors have had use in agriculture type applications for many years. These applications have tended to be belt driven types with electric motors capable of only one speed. Any change in speed required needed to have the gear ratio changed. This has required other […]

Lowell Christensen, VP Engineering TruTech Specialty Motors Magnetics 2014 Orlando Florida Jan 29 & 30, 2014 This presentation will discuss a case study comparing the design of an in-hub permanent magnet motor in a mobility cart used to move supplies from one location to another. This case study will compare […]

Lowell Christensen, VP Engineering TruTech Specialty Motors Magnetics 2013 Orlando Florida Feb 8 & 9, 2013 This presentation will discuss the effects of changing the Flux density in the airgap of a Permanent magnet Brushless Permanent Magnet Servo motor on the overall motor performance. The air gap flux density is […]

Presented by Lowell Christensen Magnetics Conference 2011 March 1 & 2 2011 San Antonio Texas Motors have been around for many years and are a major usage of the energy from the power grid. Over history the generation of power has been fairly cheap and abundant so that the efficiency […]

Presented by Lowell Christensen Magnetics Conference 2010 January 28 + 29, 2010 Orlando Florida Electric motors have had use in agriculture type applications for many years. These applications have tended to be belt driven types with electric motors capable of only one speed. Any change in speed required needed to […]

Article for Machine Design Magazine Lowell Christensen, Founder and VP of Engineering TruTech Specialty Motors Motors that are built into the hub of a wheel can offer many advantages to mobility applications. These can range in sizes from small over the road vehicles down to mobility scooters. The main reason […]
