PMD has extensive experience designing the mechanical as well as magnetic aspects of various types of motors and actuators.

PMD often works as a subcontractor for motor design manufacturers regarding the mechanical aspects of the project, teaming up with electrical engineers on the project.  PMD could either recommend a single-source solution for various types of motors or actuators, or work with a client to create their own design.

Several examples of past motor and actuator projects include the following:

Voice Coil Actuators

Design of "macro" actuator for disk drive read-write testing machines, including all of the magnetic design.

Piezo-Driven Micro Actuators

Design of "micro" flexure-based actuator for disk drive read-write testing machines

Magnetrostrictive-Driven Micro Actuators

Design of "micro" flexure-based actuator for disk drive read-write testing machines, including all of the magnetic design.  Micro actuator was able to achieve a first resonant frequency of 2kHz, with a range of travel of 20 micro inches.

Brushless DC Motors and Generators

Worked as a subcontractor for a leading manufacturer of high power density Brushless DC motors and generators, providing all mechanical design aspects of high-rpm motors and generators.  Designs have included motors as small as .63 inch Outer Diameter (16mm), up to as large as 8 inch Outer Diameter.

DC Torquer Style Actuators

Design of "macro" actuator for disk drive read-write testing machines, including all of the magnetic design.
