Chemical compatibility in electric motors presents several challenges that can impact motor performance, reliability, and longevity. Sinotech’s custom motor designs address chemical compatibility issues from conception to production. Some of the key challenges include: Corrosion: Exposure to corrosive chemicals, such as acids, alkalis, salts, and solvents, can lead to corrosion of motor components, including metal surfaces, bearings, and insulation materials. Corrosion weakens materials, degrades surfaces, and compromises the structural integrity of motor parts, ultimately leading to premature failure. Degradation of Insulation Materials: Chemical exposure can degrade insulation materials used in motor windings, such as varnishes, resins, and tapes. Degradation of…
AC Motor Uses
AC motors have been the workhorses of numerous industries for over a century and are still widely used today. As one of the earliest electric motors developed for industrial use, AC motors enabled factories and businesses to power different types of equipment. Though newer motor technologies have come along since then, AC motors remain an attractive choice for applications that demand high reliability, flexibility of speed control, and ease of maintenance over long operational periods. Whether used to drive conveyor belts in a packaging facility or power ventilation systems in building HVAC equipment, AC motors fulfill a variety of rotational…

Reveals Secrets of China Sourcing: The Risks
Do you need to source materials from China but hesitate because of the risks? Many companies find themselves in this position as more and more manufacturers outsource their production overseas. The good news is that sourcing from China doesn’t have to be a blind leap into the unknown. Every international venture indeed involves some risk, but understanding these risks can help put your mind at ease about exploring a new market for your industry. If you’re interested in this new venture, Sinotech’s President, Michael Bloom, will give you some ideas about the different risks and how to mitigate them. Mitigating…
The Lee Valve Company Finally Has Competition
The expiration of U.S. Patent 5.819,799, held by the Lee Company of Westbrook, CT has opened the doors to competition in the manufacture of high-speed solenoid-operated microfluidic valves. These microfluidic valves are used in a wide range of industrial, medical and research applications. One such application is inkjet valves for large character drop-on-demand (DOD) printing. Sinotech has manufactured microfluidic valves, including inkjet valves, for decades. Now, with the expiration of the Lee Company patent, Sinotech is able to offer microfluidic valves and inkjet valves at less than one half the cost of Lee valves. Chemical Compatibility One of the biggest…
Shaft Material Selection – More Testing May be Needed
Shafts are a key component in most rotating equipment. Considering the best material for your electric motor shaft. There are several considerations: Cost and Material Deficiencies. Most Common Shaft Material Most motor manufacturers use SAE 1045 in either cold-rolled (CRS) or hot-rolled steel (HRS). Forged or normalized, C1045 is a medium carbon, medium tensile steel. This steel shows good strength, toughness and wear resistance. Axles, bolts, forged connecting rods, crankshafts, torsion bars, light gears, guide rods etc use Other materials include sulfurized SAE 1117, SAE 1137, SAE 1144, hot-rolled SAE 1035, and cold-rolled SAE 1018. A ground stock of any…
BLDC Motor Manufacturers Increase Energy Grid Efficiency
With environmental, economic, geopolitical and environmental concerns making headlines, the concept of energy efficiency is gaining broad support across the globe. Efficiency is often associated with how the end user consumes energy, but it also has to do with how energy is generated and distributed. As BLDC motor manufacturers have their devices installed in products that operate on direct current (DC), the use of direct currents from DC sources avoids energy losses related to converting DC power to AC power and then back to DC power. With motors accounting for up to half of the planet’s energy consumption, brushless DC…
Need for Investment Casting Increases for Medical Applications
Custom investment casting is used in many medical products that aid in the increasing quality of care patients receive, time spent in recovery, and the prevention of complications. The science is responsible for some of the greatest achievements in modern medicine, including knee and hip replacements. A recent study about knee and hip arthroplasties found that 7.2 million Americans have an implant. It’s estimated that between 2005 and 2013, the number of total knee replacements in the U.S. will increase by 600 percent. Hip replacements will increase by about 200 percent over the same period. Investment casting manufacturers have an…
