We’ve just launched a new video series, where I talk about some of the specific applications where Alva’s breakthrough FiberPrinting™ motor technology is used.

The first video in the series is focused on Exoskeletons. In case you missed it, you can watch the video here.

I wanted to briefly summarize the main points of the video, specifically what are the common motor requirements engineers have when designing exoskeletons and why our FiberPrinted™ frameless motors are the smart choice.

‍So, what is a robotic exoskeleton?

Exoskeletons are wearable machines that help people with health/mobility issues or to perform demanding tasks. Rehab and physical therapy are common use cases for exoskeletons helping patients to walk again after surgery and perform day-to-day tasks.

Also, in military environments, exoskeletons are increasingly used to help soldiers carry heavier loads over longer distances.

What are the typical motor requirements?

Since an exoskeleton is wearable, one of the key requirements is to be as compact and lightweight as possible to maximize utility.

Efficiency is also important to extend battery life and it can’t dissipate a lot of heat as this could cause injuries or burn the individual wearing it.

Given these requirements, there are usually some give and take when it comes to performance.

Why are Alva FiberPrinted™ motors great for this application?

There’s several reasons why this is a perfect application for our motor technology.

Firstly, Alva motors are top of the line in terms of torque density. This enables a big reduction in the overall weight of the machine without compromising lifting capacity.

FiberPrinted™ motors also have high efficiency which ensures minimal heat development even during strenuous activities. This ensures that the individual wearing the exoskeleton is comfortable at all times.

On top of this, Alva motors have zero cogging, allowing the exoskeleton to seamlessly integrate with the natural movements of the human body and they are the thinnest and lightest on the market which helps a lot for the overall compactness of the device.

Can Alva customize FiberPrinted™ motors to exact requirements?

I know design engineers would always prefer a standard product but the reality is most of the time for these applications, some level of customization is required.

The good news is that FiberPrinting™ is the most flexible motor manufacturing technology which allows us to do custom designs in the time it takes our competitors to ship a standard product.

As a first step, we suggest you take a look at our SlimTorq™ range of motors which are available as standard in thousands of options.
