Mirmex Motor said its AI-developed electric motors and flexible circuits can make it easier to design and manufacture devices such as prosthetics and surgical robots.
Startup IQ Motion Control said the Vertiq 6806, its latest motor module, will help revolutionize the robotics and aerial drone industry.
The permanent magnetic is a quiet, unobtrusive work horse in so many applications that it, like many things that are mechatronics related, is mind bogglingly (is that a word?) pervasive. Magnets are the key material technology to enable high efficiency and power dense electric motors. And electric motors are everywhere. The particular magentic material that […]
I was talking with some friends about control technology and made the observation that over the last decade the progress in the control field has been really amazing. Particularly, the processor technology that is available for controlling electric motors is operating 1000 times faster than the control platforms of a decade ago. We look at […]
A friend of mine finally got delivery of a Tesla Roadster. This prompted discussion of the drive train and the fact that Tesla has had to go from two speed transmissions which were failing to a transmissionless drive train. The ultimate mechatronic challenge, the electric car, is also a challenger in terms of the precise […]
One of the mechatronic Top Ten applications has to be the hard disk drive. Strangely, it is not an application that you hear much about. That’s probably because unless you work on hard disk drive design, you pretty much take for granted that little black box that stores all your information. So the group that […]
Another aspect of applying electric motors to power mechanical systems is the relationship between peak power and continuous power. In mechanical systems the forces required to start a load may have no relationship to the power required to keep the system running. Further, the ideal demand for mechanical power may occur at a speed that […]
There is an interesting problem with applying electric motors that is a constant source of difficulty, the nature of peak power versus continuous power. The problem is that few systems operate at a statistical average power demand. Frequently, this causes equipment designers to oversize the motor for the application. At the same time, however, this […]
Most motor sizing programs deal with time and torque analysis. The traditional tradeoff is more torque for less time. As an aside, the increase in electric motor torque comes with increased motor inertia, so it’s not for free. And the motor costs are always a factor. But this assumes that inertia is fixed. And that’s […]
I have worked around electric motors for a long time. It still blows my mind that we can’t seem to settle on common terms and definitions of things we work with on a daily basis. When is a motor AC Synchronous or DC Brushless? They are identical. Same motor. So you have to start from […]
Hope everyone had a great holiday and a successful year in 2007. I was reviewing the Department of Commerce figures for electric motors. Hey, its just something I do. A few years ago when I was hired to help a young high tech motor company in Denver understand the marketplace, we started with the Department […]
