Design and analyze motors and electronic control in existing and new products. Motor sizes range from sub fractional HP (for disk drives) to tens of HP (for electric vehicles). Participated in mechanical design and manufacturing of motors and actuators (and their compatibility with the final product) for US and international companies.
Developed spindle-drive motor assemblies and magnetic actuators with conventional and Proprietary designs for this startup company. Supplied prototypes to several customers which resulted in large orders and led to volume production. My major involvement was in new designs and projects.
Investigated design of DC motors and their performance with or without switching amplifiers. Also performed research on switching devices and their circuits. Led a major project from design to completion.
Performed feasibility study and design of a brushless pump and its electronic control circuit. Temporary position.

Ph.D. title: Commutation of a Brushless Motor Using Power Transistors.
The Ph.D. project was an investigation into the application of power transistors in the switching of a DC brushless motor. The design of the motor and the electronic commutator were also part of the project. Thyristors were used in the power supply, and extensive work was done on logic circuits.
Six months of course work in Mathematics (Fourier & Laplace), statistics, electromagnetic theory, machine theory (and generalized theory), power system analysis & Stability, conventional machine design and computer programming. In the remaining six months a research project was carried out on the operation of an eddy-current coupling.
The degree included both heavy and light current subjects. The final year project was on the design of a 3-phase induction motor.
1977 Associate Member of Institution of Electrical Engineers, UK.
