Extern varvtalsmätning på en permanentmagnetiserad likströmsmotor

Karlin, Andreas and Eliasson Borg, Sarah (2016)
Computer Science and Engineering (BSc)
Abstract
This bachelor thesis was performed at BorgWarner AB in Landskrona. The
assignment was to investigate different methods for external measurement of a
permanent magnetized DC motor speed in revolutions per minute when you
have no access to the rotor. The task was to examine different measurement
methods, to produce a finished circuit that converts the signal frequency to
rpm and build a complete tool.
A couple of different measurement methods were tested to draw conclusions
for any of the methods that were preferred. Most of the work was to develop
the circuit that gave a good enough signal to enter in the F/V-converter. This
circuit was then mounted in a hand tool with the F/V-converters output
coupled to a display.
The finished tool came... (More)

coupled to a display.
The finished tool came to consist of a holder of the pick-up inductor and the
hand tool with a display representing the motor rpm. The hand tool would also
include two oscilloscope outputs for analog and digital signal which was
integrated and an input for a power supply. (Less)
