Today’s most challenging battery-operated tools require power, speed, and efficiency within the most ergonomic package. Studies have proven that users prefer a smaller and lighter tool with a high level of performance. The ergonomics needs have tremendously increased in the last few years to highlight operator comfort and efficiency while using battery-powered tools.  battery_operated_drill_construction_site

There are multiple ways to lighten the tool. For example, we recognize the battery of the tool as one of the heaviest components, therefore the trend is to reduce the battery size. Lowering the battery size will affect the number of cells and thus the voltage: The smaller the battery, the lower voltage.

Industrial power tools support the increase in productivity while remaining versatile. We achieve productivity gains thanks to faster working cycles, so the tool should deliver higher speeds. We derive versatility from an increased torque capacity. 

The challenge lives in the ability to design and produce motors than can deliver high speeds at low voltage, which is against physical laws.

Portescap’s Ultra EC™ Brushless DC motors are designed to provide high speed despite the low voltage availability while delivering excellent peak torque capability by using the maximum peak current capacity of the battery. Below, you can see an example of this performance in our 30ECT64 10B 4 and our 35ECS60 5C 8 Ultra EC motors.

Based on a slotless design, bringing the advantage of no-cogging torque and very low iron losses compared to typical slotted motor design, these high-performance density motors will enhance your hand tool and help you meet your battery device goals.

You can be certain that these motors were designed with your key targets in mind. Our Ultra EC motors:

  • Increase productivity thanks to high speed capability
  • Drive time savings thanks to lower Joule & Iron losses
  • Improve precision thanks to no-cogging torque
  • Reduce operator fatigue due to their lightweight design
