During development of electronic products, several measurements are performed to ensure the electromagnetic disturbances are in such levels permitted by costumer requirements. Normally these tests are performed in certified laboratories. This usually causes high impact on timing plan and development costs. In order to reduce the time and cost involved on pre-compliance EMC tests, a Transverse Electromagnetic (TEM) cell was used as a tool for fast analysis of proposed design solutions during development of a brushless motor controller. The TEM was used as an Antenna to measure the electromagnetic disturbances (magnetic field) generated by the EUT (Equipment Under Test). A mathematical correlation between the voltage measured using the Antenna (TEM) and results found in a Certified Laboratory are compared and presented.

During the design and development of oil pumps, performance tests are required to provide accurate data about the oil flow and pressure relationships of pump under test. These tests are performed in test rig, which simulate the pump operation in the vehicle engine. The test rig is also an useful tool for the engineer, assisting in developing and new solutions testing. This paper describes the evaluation of performance results on the correlation in the use of the test fluid with the oils used in the final application.
