Every year, universal ac-dc motors get more compact, complicated and affordable. It might be more practical implementations of performance or more innovative deployment of technology. We can't get enough, and we're here to introduce you six development directions to them all.

l Sometimes You Have to Ask: What's better, brushed or brushless?

Future trend for universal ac-dc motor will concentrate on brushless motor. Traditional DC motors were widely used due to the prevalence of DC power supply. These motors were all brushed motors. While brushed motors were relatively easy to manufacture and came with affordable accessories, they had several drawbacks. These included troublesome accessory replacement procedures, short attachment lifespan, high heating rate, large commutation sparks, significant losses, and severe electromagnetic interference. Brushless motors come in various types and offer significant advantages over brushed motors in terms of universal ac-dc motors. They exhibit minimal wear, produce low noise, cause less interference, and have low maintenance costs.


l Met Motors That Get More Compact and Miniaturized

There is a growing need for motors to be compact and smaller in size, particularly in portable products. This requirement for motor size reduction is evident in the evolution of electronic computers, starting from the first generation of computers to desktop computers, then to notebook computers, and further to devices like iPads and mobile phones. All these advancements reflect the increasing demand for motors to be miniaturized.


l How Applications Get Help From Direct Drive Tech ?

Direct drive technology will be more commercially viable. Universal ac-dc motors typically operate at high speeds, often reaching several hundred or even thousands of revolutions per minute. It becomes challenging to transition smoothly between high and low speeds at such rapid operating speeds, even though many applications require this capability. Consequently, universal ac-dc motors need to incorporate a speed conversion system to meet these demands. However, implementing such a conversion system will unavoidably increase the overall size of the motor system and may also impact the precision and efficiency of the equipment. To effectively address this issue, the development of direct drive technology in universal ac-dc motor drives becomes crucial.


l Integrate intelligence that is most forward-thinking and exciting

Modern motors play a crucial role not only in providing power for the overall electromechanical system but also in offering functionalities such as balance and adjustment for motorized systems. In response to the increasing demands from consumers, motors are now expected to possess features like self-adaptation and self-renewal, enabling personalized services for different tasks. This integration of intelligence into modern electronic systems exemplifies the advancement of modern motors. Achieving such intelligentization requires the comprehensive application of diverse electronic theories, smart sensors, and high-performance materials.


l Speed Regulation Needs to Be Prepared

Greater use of speed regulation improves motor efficiency. Traditional motors typically operate at a fixed speed, often controlled by a simple on/off switch. However, in practical applications, it is often necessary to adjust the motor's speed. This frequent switching can lead to wear and tear on internal components, as well as place additional strain on the motor controller and power grid. By implementing a speed regulation system, motors can operate with improved efficiency, resulting in power savings.


l Extreme Speed Is On The Industry's Radar

There is an increasing demand for motors to operate at extreme speeds, whether maintaining a very high or very slow rotation. To boost direct drive technology, we will see the rapid development of extreme-speed motors. Achieving extreme speeds not only facilitates the direct drive of the motor but also enhances the efficiency of the motor's operation and the accuracy of the equipment it powers.
