It is our mission to provide product developers with cost-effective brushless permanent magnet motor and control solutions. For example, to replace uninspired off-the-shelf induction, belt-driven or geared motors that don’t embrace product innovation and/or performance. To do so we started our journey to master direct drive brushless permanent magnet motors and electronic controllers in the 1980’s.
We infuse all the techniques, skills, methods and processes we have perfected over the last 30 years in the electric drives we develop and manufacture today. Complementing our electronically sophisticated and yet mechanically simple drive solutions with high-end technology.
We specialize in permanent magnet synchronous motors (PMSM), field-oriented control (FOC), magnetic design and automated manufacturing. In addition, we use our unique lamination construction, engineering plastic rotors, proprietary design tools and elaborate testing facilities. Learn more about our technology below.
A direct drive motor is a type of permanent-magnet synchronous motor which directly drives the load. In a DD motor, the use of a transmission or gearbox is eliminated—meaning that the number of moving parts in the system is reduced tremendously. The result is a very efficient electric motor and a quiet, highly dynamic operation. Consequently, the direct drive mechanism gives a motor a very high lifetime.
Engineers and equipment owners are starting to adopt permanent magnet motor solutions for many different applications—for their smaller size and higher efficiencies. Permanent magnet motors are a great solution for applications such as fans, blowers, and pumps.
Field-oriented control (FOC) may also be known as vector control. It applies to three-phase brushless motors that operate in sinusoidal mode. FOC is a variable frequency drive (VFD) control method and is used to precisely control motor speed and torque by varying the input frequency and voltage.
The primary goal for our motor designers is to maximize the motor output ratings while minimizing the mass. Fisher & Paykel Technologies uses the external rotor design for its direct drive motors in order to achieve this.
Internal rotor motors have great ability to dissipate heat. Heat directly impacts the motor’s ability to generate torque, so better heat dissipation improves efficiency. Another benefit of the internal rotor motor lies in the small moment of inertia (tendency to resist angular acceleration) of the rotating shaft. This quality gives this type of electric motor an incredible ability to run at high speeds.
