Motor till unikt luftvärmeväxlarsystem
Gtherm is an innovation company who has an unique air heat exchanger underdevelopment. The purpose of this thesis is to provide data of suitable motors for theheat exchanger and to find suitable motor suppliers.A motor specification was designed. It is an important basis for the search of suitablemotors. A compilation was made of nine motor suppliers and the suitable motorsfrom those. The compilation can be used by GTherm in their choice of suppliers andmotors.The compilation of the demands on the motor and analysis of suppliers indicated thatthere were no standard motors available to GTherms air heat exchanger. Adaptationof motor is required to meet the system requirements.Power Efficiency is the keyword for an air heat exchanger so tests were performedon prototype to calculate this. Suppliers have long delivery time for customizedmotors and because of the lack of time a borrowed standard motor was used for themeasurement. The motor was satisfactory enough to perform the tests but wouldprobably not have been selected for the production of the air heat exchanger. Basedon measured data, electric power (SFP) was calculated for the prototype. The resultsshowed that air heat exchange system was non electrical efficiency because theestimated SFP value was too high. This is probably because the prototype had gaps inthe sealing that produced air leakage.
