“…According to equation (15), when the slope of ground wire is θ, the robot goes downhill unpowered at a constant speed v, and the armature resistance R T w2 will increase linearly as the temperature of the armature winding of the rear wheel traveling motor rises. In order to keep the robot going downhill at a constant speed without power, the duty 6 Complexity ratio u 0 of PWM wave in the energy consumption control system of the rear wheel walking motor will also increase linearly.…”

“…Although these methods can control motor speed well, the temperature rise characteristics of the motor are not studied. Temperature rise characteristics of permanent magnet synchronous motor were analyzed in [13][14][15]. According to the special structure and related theories of the motor, the equivalent model of the motor temperature rise was established, and the correctness of the model was verified by experiments in [16][17][18].…”

In order to avoid the motor damage caused by excessive temperature rise of armature winding of the walking motor during braking of high-voltage inspection robot in complexity microgrid networks, an unpowered downhill speed and energy recovery optimization control strategy is proposed based on temperature rise characteristics of the walking motor. Firstly, the thermal equivalent circuit model of the walking motor is established, and the mapping relationship between the armature winding temperature of the walking motor and ambient temperature is solved; secondly, the influence of armature winding temperature on unpowered downhill speed and energy recovery control strategy of robot is analyzed; thirdly, according to the temperature of front and rear wheel walking motors and the temperature difference between them, the optimal control strategy of unpowered downhill speed and energy recovery of robot is put forward; fourthly, by adjusting the duty ratio u of the energy consumption speed control system and the front wheel feedback brake distribution factor λ , the temperature difference between the front and rear wheel walking motors is reduced. Through the experimental analysis on the simulated line, it is verified that the unpowered downhill speed and energy recovery optimization control method based on the temperature rise characteristics of the walking motor can effectively reduce the temperature difference between the front and rear wheels.

“…The lumped parameter method is mainly employed for analysis of thermal resistance network as well as for calculation of conduction, convection, radiation and contact thermal resistances for different components of actuators [12,13]. For finite element method (FEM), the heat conduction in solid element with specified conductivity can be modelled, but convection and radiation boundaries must be based on empirical correlations [14][15][16].…”

Multiphysics methodology is a preferred tool for the design and optimization of electromagnetic linear actuators (EMLA). In this paper, a multiphysics method was proposed, which uses the non-simplified energy consumption distribution as the heat source for temperature field calculation, adjusts the material properties by temperature, and considers the interaction between motion (including impact) and loss. Then comprehensive experiments and quantitative analysis were carried out. The results show that the errors between simulated and experimental results of indices such as landing velocity, input circulating energy, iron loss and temperature rise of prototype were less than 5%. The prototype's total iron loss was decreased by 57.6% with fixed armature and dynamic response time was decreased by 10.4% without eddy current compared with the normal condition. This result validated the precision and necessity of the coupling model. In addition to being applied to EMLA, the proposed methodology can be used for analysis and design of a wide range of electromagnetic actuators.
