The world's smallest and most powerful micro motor

Piezoelectric ultrasonic motors have two significant advantages, namely their high energy density and their simple structure, which both contribute to their miniaturization. We have built a prototype micro ultrasonic motor using a stator with a volume of approximately one cubic millimeter. Our experiments have shown that the prototype motor generates a torque of more than 10 μNm with a one cubic millimeter stator. This novel motor is now the smallest micro ultrasonic motor that has been developed with a practical torque.




Micro actuators are needed for numerous applications, ranging from mobile and wearable devices to minimally invasive medical devices. However, the limitations associated with their fabrication have restricted their deployment at the one-millimeter scale. The most common electromagnetic motors require the miniaturization of many complicated components such as coils, magnets, and bearings, and exhibit severe torque dissipation due to the scaling. Electrostatic motors enable excellent scalability by using microelectromechanical systems (MEMS) technology, but their weak driving force has limited their further development.

According to Mashimo, "The simplicity of the stator structure enabled the miniaturization without having to use any special machining process. This prototype stator is much simpler than those of other existing ultrasonic motors."
The next goal of this research is to improve the values of performance parameters for practical applications, such as energy efficiency and lifetime. In future, the proposed micro motors may actuate micro forceps embedded in endoscopes for safe and less-invasive operations.

China, the world's largest manufacturer of micromotors, produced 12.4 billion units in 2015, up 6.0% from a year ago, and accounting for 70.9% of the global total. The country's micromotor output is predicted to be close to 17 billion units in 2020 at a CAGR of around 7.0% during 2016-2020.

Keymicromotor manufacturers in China includeJohnson Electric, Welling Holding Limited, Zhongshan Broad-Ocean Motor Co., Ltd., and Wolong Electric Group Co., Ltd. Johnson Electric, as the largest micromotor manufacturer in China, achieves annual revenue of over USD1 billion, with a global market share of 4.3% in 2015.

In China, micromotor finds its application primarily in traditional fields, such as audio products, household appliances, and automobile, which held a combined proportion of 52.4% in 2015. As traditional application markets gradually grow saturated, main drivers of micromotor growth will be emerging sectors like new energy vehicle, wearable device, robot, UAV, and smart home.

Information Industry: China's shipments of VCM for mobile terminals were 542kk in 2015, up 12.9% year on year, occupying 45.9% of the world's total, largely driven by smartphones and tablet PCs. With gradual saturation of the markets for traditional consumer electronics like smartphone and tablet PC, wearable devices will become a new growth area, further boosting demand for micromotor. The Chinese wearable device market is predicted to expand at annual growth rate of over 25%.

Automobile: In 2015, China's demand for automotive micromotor was 1.02 billion units (24.9% of the global total, expected to rise to 1.62 billion units in 2020), less than 3% coming from new energy vehicle. New energy vehicle sales grew at a compound annual rate of 152.1% during 2011-2015 in China and, with the support of national and local policies, will maintain the strong growth momentum over the next couple of years. It is estimated that the market of micromotors for new energy vehicle will keep going up by over 40% annually during 2016-2020 with the demand exceeding 150 million units in 2020.

Robot: 248,000 industrial robots and 6.41 million service robots were sold globally in 2015, up 8.3% and 35.7% from a year earlier, respectively, together creating a demand of about 66.6 million micromotors (an estimate of more than 300 million units in 2020). In 2015, China accounted for 22.9% of the world's industrial robot sales and only about 5.0% of service robot sales, indicating a huge space for growth.

Consumer-grade UAV: In 2015, global consumer-grade UAV sales exceeded 200,000 units, compared with only less than 20,000 units in China. As low-altitude airspace is gradually opened, the Chinese UAV market will usher in a period of rapid growth at a rate of over 50%.

In addition, the new markets for 3D printing, smart home, medical equipment, and automation laboratory supported by policies will also kick into high gear, further driving the demand for micromotors.

For high speed micro motor applications up to 38,000 rpm including light deburring of cast pieces, bright cutting in jewelry making and fine detailing in wood. Kit includes control box, handpiece with 2.35mm (3/32") or 1/8" collet (depending on choice of collet installed), variable speed foot control, handpiece cradle, spare pair of motor brushes, spare fuse and collet changing wrenches. The back of the control box has a convenient Voltage Selector switch for operating with either 115 or 230 Volt operation. This Kit is already set for 110-115 Volt use. The control converts AC current to DC current required for the handpiece. Compared to flexible shaft machines, micromotors have less torque, however, their higher speed results in a comparable rate of material removal with a lighter touch. The simple cord connection between the handpiece motor and control box is another key advantage. Unlike the "drag" and general restriction in movement that you have with a shaft and sheath, micromotors offer much greater freedom of movement.

Is The Curing Light Dangerous Or Harmful To Look At?

The dental curing light is a very strong blue light.  It it not a laser or a UV light so it will not cause any damage to your teeth or gums.  The only danger is if you look directly at the light for too long.  Similar to how your eyes will hurt if you look at the sun for too long.  Dentists and assistants are advised not to look at the light for long periods of time.

There are two types of curing lights used by dentists.  There is a halogen curing light and an LED curing light.  Most modern curing lights are LED as they do not overheat like the halogen curing lights do.  The only danger with the halogen light is that the heat it produces could potentially hurt the pulp of the tooth or the soft tissues in the mouth.  Although this is possible, it is very unlikely.  The majority of dentists use LED curing lights these days.

What Does The Orange Shield Do?
The orange shield is a filter so that your dentist and assistant can still look in your mouth without the strong blue light hurting their eyes.  The light is okay to look at for a few seconds but it’s not nice for dental staff to look at for too long.

What Is The Blue Curing Light Dentists Use And Is It Dangerous?
Have you noticed the glow of a blue light during your dental visits?  People often wonder what this light is for used for and whether it’s dangerous or not.  The blue light is called a curing light and it is used for setting white fillings.

What Does The Blue Light Do?The blue light sets fissure sealants, fillings and cement in a matter of seconds.  When fillings are placed in the tooth they are very soft so they can be moulded to the correct shape by the dentist.  When the dentist is happy with the shape of the filling they will set it with this light.  The blue light makes the filling go rock hard and strong enough to chew on.  The blue light is also used when having braces fitted to set the cement which holds the brackets on your teeth.

10 Interesting Things About the Dentist’s Hanpieces

1.There are two main types of dental drills: the high speed handpiece and the slow-speed.  The high-speed drill rotates around 250,000 RPM.  That means it spins around more than 4,000 times each second!

Even the relatively slow dental drill rotates at about 8,000 RPM.  By comparison, this DeWalt Drill is three times slower with a top speed of 2,500 RPM.

2 .After using the dental drill on your tooth for 30 seconds, your dentist is subjected to as much bacteria as they would be had you sneezed right in their face (Source).  That’s one of the reasons most dentists wear face masks.

3 .The high-speed dental drill shoots out water as it spins, as you can see in the photo above.  If it didn’t, the friction would cause your tooth to get so hot during a filling that it could possibly damage the nerve inside your tooth.

4.Many dentists now refer to the dental drill as a low speed handpiece to make it seem more friendly and enticing.

5 .The dental drill has to withstand the rigors of sterilization after every use, which means it gets heated to 250° Fahrenheit with pressurized steam for at least 15 minutes.

6 .The very first dental drill appears to have been a bow drill used by an ancient civilization about 9,000 years ago.

7 .The drill bits that dentists use are made of tungsten-carbide.  Some have blades to cut teeth, like in the photo below, and others are coated with diamonds to give a sandpaper-like smoothing effect (see photo below).

8 .As recently as the early 20th century, many dentists used drills that were powered by a pedal that the dentist would pump with his foot.

9 .The distinct shrill sound that the high-speed dental drill makes can be a major factor in people’s fear of the dentist.  Even for those who don’t have dental fear, the dental drill’s noise can be very unpleasant.

10 .Dental drills can be expensive, with many costing over $1,000.  That’s a lot more expensive than your average home-improvement drill.
