The existing synchronous sampling method was put into use in data acquisition system of the motor temperature rise test so that it can automatically test the motor temperature rise. Combining with the instance, proves the accuracy of this method. This method has the superiority of reducing errors ...

This article makes an approach detailed on the temperature rise test listed in the type testing items to large-sized increased safety synchronous motor,against the specifications of the standard for Increased safety brushless excitation synchronous motor and technical specifications of series TAW increased...
Temperature rise of the form-wound multi-conductor stator winding of a 1250-kW cage induction motor was analyzed. Eddy currents in the winding significantly affect the temperature rise. The eddy current was modeled using time-discretized finite-element analysis (FEA). The resistive losses in each ...
Thermal overloadrelays: These are devices that use a bimetallic strip or a heating element to sense the temperature rise of the motor current. When the current exceeds the preset value, the thermal element bends or melts, causing the contact to open or close.Thermal overloadrelays are simple,...
The optimization algorithm considers the efficiency, starting torque and temperature rise as objective function (which are considered separately) and nine performance related items as constraints. The PSO algorithm was implemented on a test motor and the results are compared with the Simulated Annealing ...
