Latest Patents

Westerman's latest patents include a "Method for Testing DC Motors" and a "Digital Pulse-Width Modulated Printer Escapement Control System." The first patent discloses a DC parameter motor tester that does not require coupling the motor to any mechanical device. This tester determines the steady-state speed of the motor by analyzing the frequency composition of the commutation noise and ripple in the steady-state current. By performing a fast Fourier transform on the steady-state current, it identifies the frequency at which the most power exists, allowing for accurate measurement of the motor's velocity at a given power input.

The second patent presents a digital escapement control system that operates entirely digitally, eliminating the need for tachometer feedback signals or analog-to-digital converters. This system utilizes a code wheel and detector connected to the DC motor shaft to measure the time between discrete positions of the motor. The difference between the measured time and the desired time is stored and converted into a pulse-width-modulated signal, which directly controls the motor's rotational velocity.
