Abstract: An electrical machine is disclosed. The electrical machine includes a rotor rotatable around an axis of rotation and a stator fixed against rotation with respect to the rotor and which concentrically encloses the rotor, forming an annular gap bounded radially between the rotor and the stator and through which a cooling liquid can flow. The stator is at least partially encapsulated by injection molding with a plastic sheathing. A printed circuit board with electronic components arranged on it and a central opening through which a rotor shaft of the rotor protrudes. The plastic sheathing has on a side facing the printed circuit board at least one recess in which at least one electronic component of the printed circuit board engages.

Abstract: A website-performance testing method is applicable to test multiple websites at a time. It includes steps of: setting parameters and schedule of the testing task; starting tests according to the system clock; fetching website information from the task setting; connecting to the task website and performing the test; and recording and displaying the real-time test results. It tests multiple websites at a time with the same criteria. It meets the requirements of daily testing of website speed and providing information for the website maintenance personnel or decision-makers.
