The paper deals with the experimental validations of the corrective coefficient used to take into account the skin effect in the equivalent circuit rotor resistance of induction motors with squirrel cages.

Locked rotor tests have been performed at several supply frequencies on different induction motors; the collected experimental data have been used to validate the rotor parameters analytical estimation obtained by means of a numerical procedure previously proposed by the authors.

The reported analyses regard both open and closed rotor slots. For frequencies up to 80‐100 Hz, the reported comparison between experimental and calculated skin effect corrective coefficients shows that the adopted model allows to get satisfactory results in terms of accuracy, lower than 3 percent for open rotor slot machines. The upper frequency limit has to be judged taking into account the objective difficulties to estimate accurate values of the rotor parameters from experimental tests.

The proposed algorithm can be easily implemented and added to self‐made induction motor design software tools.

The proposed procedure allows the computation of the skin effect in induction motor squirrel cage without the use of finite element method approaches.

The purpose of this research is to examine the effects of congruence between the ideal self-image of a game player and the game character on identification and interaction with the game character, perceived game power and performance, character attachment and willingness to spend money on the game character.

A total of 347 online game players participated in an online survey posted via the nationwide crowdsourcing web service Mechanical Turk in the US. A structural equation modelling was conducted using a maximum-likelihood estimation procedure to test the relationships among the variables.

The results revealed a significant positive impact of congruence between a game character and the ideal self-image of a game player on identification and interaction with the game character, perceived game power, game performance, attachment to the game character and willingness to spend money on the game character.

Although significant research has been conducted in the area of online gaming, limited attention has been given to the strategic game content that stimulates a player's intention to purchase game items. Due to the challenges in sales growth in the game industry caused by business model shifts from a subscription-based model to a free-to-play one, it is important for marketing practitioners to motivate game players to continue playing the game and purchase game items. The results of this study provide valuable strategic insights to overcome the limitations of existing marketing strategies in the online game business.
