Lion PowerCustom Motor Controller Design
Drive electronics and control loops for BLDC, PMSM, and more, tuned to the motor you use.
What clients say
Quoted feedback from past projects.
Samo and his team took our project of developing the world's first USB-C charging for eBikes. Their expertise quickly identified improvements in our ideas and their commitment delivered the final product before the deadline. This allowed us to beat our competition as first to market.
We were experiencing issue after issue with our motor controller modules and that's why we decided to get our own motor controller developed. Engineers at Lion Power made a really high-quality product which cut our field failure rate by 80%. Definitely recommend.
We just completed our second project with Samo and are planning a third one. We went through a few 'low budget' freelancers before we found Samo and the results were 'low quality', like expected. Samo really turned things around for us. He took over the whole electronic system development and perfectly integrated with our mechanical department. The result was a high-power battery-operated LED light that passed all certifications with ease and is successfully selling.
We hired Samo because we needed scientific grade motor controllers for our robots that we just couldn't find elsewhere. Samo proved to be a reliable and trustworthy partner as he quickly and diligently responded to many requirement changes from our side during the project. Recommend.
I had an academic paper that described the high-voltage power supply necessary for our product. I reached out to more than 20 contractors and they all declined because they just didn't see the value in studying and learning something new. Samo gladly took up the challenge, reviewed multiple other academic papers, proved as a worthy discussion partner, improved upon the idea and finally built the power supply. It is now manufactured in multiple thousand units annually. Best contractor I had.
The stock motor drives that we used in our heat pump just didn't perform well enough and the price was ridiculous. We decided to invest in the development of our own drive so that we could own the design and manufacture it at a lower cost. Samo and his team proved more than adequate and they delivered the designs and validated prototypes ahead of schedule. This cost for our motor drive was reduced by 60%. Best investment we made.
How we work
The same sequence, whether the deliverable is one board or a small production run.
Consult
Define the electrical and mechanical constraints — load, environment, volume, timeline.
Design
Topology, component selection, schematic and layout — reviewed against the real requirements.
Prototype
Bring-up, bench testing, and firmware to get a working unit in your hands fast.
Validate
Thermal, load, and reliability testing against the conditions the product will actually face.
Deliver
Production-ready documentation, firmware, and hand-off — or ongoing support, as needed.
Selected work
A few recent motor controller builds, framed by the problem they solved.
Synchronous Motor Control Card for Robotic Arm Actuators
Hardware and firmware control loops tuned to the client's actuator motors improved robotic-arm precision 30% — fewer defects, fewer mistakes in use.
High-Power Deep-Sea LED Light with Driver
Water-cooled, metal-core PCB driver design for a high-power deep-sea LED light — hotspot temperature down 60%, MTBF up 30%, without growing the housing.
Complete Electronics Platform for a Deep-Sea Exploration Light
Four boards, one team — charger, BMS, LED driver, and battery pack, developed end-to-end so the client's electronics could run fully outsourced.
