Brushless DC Motors

A Brushless DC Motor offers a great combination of durability, efficiency, torque and speed in a compact package suitable for your application.

Portescap BLDC Motor technology continues to push the curve of high performance in both slotted and slotless DC brushless motors. With exceptional torque and speed, higher efficiency and package sizes suited to meet your needs, brushless DC motors meet even the most stringent requirements. A brushless DC motor offers excellent speed and position control, long life, and high torque density. Slotless electric brushless DC motors use a cylindrical ironless coil made in the same winding technique as ironless DC motors, while the slotted DC brushless motors are built with stators consisting of the latest technology in lamination and windings. Both are electronically commutated and have 3 winding phases. Our slotted brushless DC motors are manufactured in the USA and targeted towards performance-critical surgical power devices and also offer sterilization capabilities.

The latest developments include a new compact brushless DC motor that is only 24mm long for a 16mm diameter. This motor offers up to 30% higher torque over similar motors on the market and can also include an integrated electronic driver without even adding to the motor length.
Portescap also offers larger motors such as a new 40mm diameter 4 pole motor, offering both high speed and high peak torque capability without compromising on the smooth operation thanks to its slotless stator design.

We also offer an optimized line of brushless DC motors / miniature brushless motors, Ultra EC, designed in Switzerland. This family of small dc motors helps you address a wide range of specific requirements for torque and speed while providing decreased iron losses, improved efficiency and cooler operation.

Our DC brushless motors perform exceptionally well in environments requiring both precision and durability. The unique design of a BLDC motor allows for several key benefits:

Ultra EC Motors

The three families of Ultra EC Brushless DC Motors not only meet a high range of requirements, but include our proprietary U coil for excellent performance, minimal iron losses and maximum efficiency
The Ultra ECTM platform offers 3 families of motors to help you address a wide range of requirements, whether it be traditional BLDC features, very high torque or very high speed. The proprietary U coil provides outstanding performance, including minimal iron losses, better efficiency and cooler operation.

One design definitely does not fit all. Not when your application has specific performance requirements for high speed, high torque or a delicate balance of both. And not when you need to deliver ultra performance at an optimized cost. That's why we created the Ultra EC platform of mini brushless motors. These electric brushless DC motors are crafted around our proprietary U coil technology. This new coil design, designed in Portescap in Switzerland, is the key to the outstanding performance of these brushless mini motors, including minimal iron losses, better efficiency and cooler operation. This unique coil design allows two-pole motors, for example, to deliver 30 % more torque compared to the same size electric brushless dc motor using a conventional coil design, plus it offers substantially lower iron losses.

Looking for Ultra high speed and maximum responsiveness? ECS brushless mini motors are tailored for high speed, direct drive applications.

  • High power and efficiency at high speeds
  • Designs can reach mechanical powers such as 180W continuously at 50,000 rpm

Motion Innovations

The Portescap R&D team is working on a number of innovative ideas and concepts to further satisfy our customer's needs.
Here are some of the concepts that are already designed and can be offered as prototypes.

  • Dual Motion Can Stack Actuator Solution: Rotary and Linear Motion in One Compact Solution

Some applications require rotary motion, such as ventilators. Others require linear motion, such as medical pipettes or syringes. When it comes to combining a rotary and a linear motion in the same application, designers often need to integrate two motorized solutions so they can control both degrees of freedom (rotation and linear) at the same time.

Portescap’s innovative Dual Motion Can Stack Actuator solution offers both rotary and linear motion inside a compact package. Designed as a stack of two permanent magnet Can Stack stepper motors, the innovative Dual Motion motor makes it possible to provide any of the following motion scenarios:
Pure linear motion in any direction (no shaft rotation)
Pure rotation, clockwise or anti-clockwise (no shaft translation along its axis)
Combined linear motion and rotation simultaneously in any direction (for example like a screw entering a threaded hole

  • Quick Response Digital Linear Actuator

Certain applications, irrespective of their industry, require linear movements with quick forward and backward motions. This will help them save a lot of process time. Portescap's newest innovative concept combines its unique Disc Magnet technology with Linear Actuator technology to enable quick linear acceleration and deceleration within the same compact package

The Disc Magnet Motor (DMM) technology provides a very high dynamic acceleration due to very low inertia. Portecap's unique low inertia Disc Magnet motion technology integrated with Linear Actuators has made it possible to achieve high acceleration/deceleration in linear actuation mode providing a unique solution for various complex application challenges.

  • SMART Coreless Brush DC Motors
High power density motors with speed-to-torque performance and SMART feature capabilities
Imagine coreless brush DC motors that can monitor reliability by triggering electrical signals that not only notifies you of the battery life but also provide you with timely feedback to operate safely and reduce downtimes.

Critical applications need a mechanism to warn users about any abrupt external factors that cause performance and reliability issues with the motor that could lead to downtime. 

Portescap’s new concept of SMART brush DC (patent pending) motors brings a unique system that continuously monitors the motor’s life. Real-time warnings trigger the device controller,  shortly after electrical signals are uploaded into the cloud application for monitoring. Portescap provides support to monitor warnings via software services.

  • High-Speed Coreless Brush DC Motors
Brush DC miniature motors that can reach speeds up to 40k rpm
Typically, high speeds are associated with brushless DC motors because of the absence of the mechanical brushes that can wear at high speeds.

It has been a challenge for applications to find a solution that requires high speeds but is also cost-sensitive. For example, disposable medical tools require both speed and low-cost options, since the operation happens only for a few minutes, after which they dispose of the tools.

BLDC motors are a solution from a speed perspective, but not from a cost perspective. Portescap’s new proprietary high-speed coreless brush DC motors deliver high-speed and are priced economically for applications where there is a short-cycle, cost efficiency, and performance is critical. Portescap’s coreless brush DC can achieve such top speeds, which is an enormous challenge while optimizing the electromechanical design & architecture of the motor.

These new concepts are available in 22mm & 24mm diameters.
