Innovative motor designs enable cooling systems to get closer to critical components for optimal cooling results, thus reducing losses and increasing continuous power output.
Miniaturization
As the demand for smaller robots that mimic human movement and require dexterity increases, industrial electric motors must also become smaller to fit inside these robots - this requires advanced designs capable of performing precise motions while meeting strict size and power specifications.
Integral electronic control systems have become an increasingly common means of realizing this goal. Bulky cabinets have given way to smaller electronics that can be integrated directly into motors or mounted directly on robot joints - reducing weight, cabling costs and overall system costs significantly.
Motor design is also evolving to reduce size. More manufacturers are turning to hairpins (enameled copper bars) as windings in stator slots, leaving fewer empty spaces and allowing more heat-dissipating material into each slot for better heat dissipation.
Motor miniaturization trends include increasing use of magnets with superior magnetic and electrical properties such as neodymium and samarium cobalt magnets that allow for smaller drives with increased torque density and power density. Customers and manufacturers are both pushing for smarter IoT enabled industrial motors, with customers demanding intelligent servo drives that can monitor and optimize motor performance to limit production downtime; manufacturers likewise seek to create motors equipped with built-in sensors and connectivity that facilitate predictive maintenance.
Power Density
Increased torque and power density is critical in many applications - particularly space and weight sensitive ones. Therefore, considerable research activity is being put towards developing lightweight motor coils using hairpins (enameled copper bars) windings inside stator slots - this enables more conductors to be placed within smaller spaces which both improve electrical performance as well as thermal leap performance of the motor.
Rotor structures have also undergone substantial innovation to increase power density. Linear Labs designed a topology without end windings that cuts total copper volume by 30% in its stator design; additionally, this company created a Halbach array that concentrates magnetic energy towards an air gap for increased power density while decreasing losses.
Other pioneers are developing double-layer shape rotor structures to increase air gap flux density, thus increasing peak and mass power density without compromising other aspects of motors such as reliability or acoustics.
Electronics Integration
Motor control electronics are essential to system performance. This includes components like its microcontroller, feedback loops, position sensors and power supply. A growing trend has been to integrate all these components onto a single chip to reduce weight and cabling costs while increasing integration levels and increasing weight reduction. Innovations like gallium nitride field-effect transistors have increased power stage efficiency to over 99.9% which allows integrated motors to reduce or even forego using heat sinks altogether.
Industrial buy electric motors are one of the top three end uses that consume the most electricity worldwide, so improving their energy efficiency could significantly slow global electricity demand growth.
Manufacturers are taking steps to increase electric motor efficiency through both process and product innovation. Process innovations seek to expand design limits while product innovations strive to further improve customer-relevant properties.
One such process innovation involves employing hairpins instead of wire windings when creating wound stator coils, thus increasing copper usage within stator slots and decreasing empty spaces between conductors, thus increasing power dissipation capacity while simultaneously decreasing joining tolerances and precompressing windings - an innovative manufacturing technology recently adopted by Schaeffler and other manufacturers.
AI/Machine Learning
Motor design requires taking into account factors like power output, dimensions and weight - this process can be lengthy, complex and costly if done through traditional engineering methods; however, with AI systems available this process can be significantly accelerated and made more cost-effective.
These systems can assist businesses in creating motors to suit various uses and optimizing motor drives and sensors for better performance. A hybrid approach combining AI's speed with human engineers' creativity and knowledge would be ideal when designing motors to fit specific purposes. buy electric motor from surplusrecord industrial electrical motors are the best buy of electric motor used electric motor for sale at surplusrecord. surplus motor are the best Buying used or surplus industrial electric motors for sale is a financially wise and environmentally responsible decision.
Motor control requires processing large volumes of data with multiple cores at once; thus requiring machine learning algorithms to run at frequencies multiple orders of magnitude higher than real-time video processing. Reconfigurable SoCs such as the Xilinx edge Versal VE1752 offer a versatile platform to support inference of machine learning models for motor control applications.
Automotive businesses provide an excellent example of how artificial intelligence technologies can benefit a business's operations. Manual labor is often employed when manufacturing cars; AI technologies enable robots to take over this part of the manufacturing process autonomously by picking parts off conveyor belts and placing them where they belong. surplus motor are the best Buying used or surplus industrial electric motors for sale is a financially wise and environmentally responsible decision.
