Resumo: It is common the disclosure of a simple and low-cost version of an electric motor type series (or universal) for pedagogical purposes that can be quite profitable. However, due to their geometry and the arrangement of the coils, it is noticed a difficulty in determining the directions and the senses of the forces responsible for the rotor torque, resulting in incomplete or inadequate explanations for their operating principle. This difficulty is present indisclosures about this engine being further supported by revelations of investigated sample teachers who dedicated to study the experiment. Considering that, this study contributes to better clarify the origin of the rotational movement of the rotor didactic version of this engine in series adjusted by application of magnetic forces involved there. It ends with a reflection that raises awareness about the educational care about the physical explanations of the operation of electric motors in general.

É comum a divulgação de determinada versão simples e de baixo custo do motor elétrico tipo série (ou universal) para fins pedagógicos que pode ser muito proveitosa. No entanto, devido à sua geometria e disposição das bobinas, percebe-se uma dificuldade para se determinar as direções e os sentidos das forças responsáveis pelo torque no rotor, originando explicações inadequadas ou incompletas do seu princípio de funcionamento. Essa dificuldade se faz presente em divulgações a respeito desse motor sendo ainda corroborada por revelações de uma amostra de professores investigada que se dedicou a estudar o experimento. Considerando isso, este estudo contribui para melhor aclarar a origem do movimento rotacional do rotor da versão didática do motor em série aqui apresentada na medida em que fica ajustada corretamente a aplicação das forças magnéticas ali envolvidas. Finaliza-se com uma reflexão que conscientiza acerca do cuidado educacional a respeito das explicações físicas do funcionamento dos motores elétricos em geral. Imprensa Universitária - UFSC2013-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2013v30n1p17710.5007/2175-7941.2013v30n1p177Caderno Brasileiro de Ensino de Física; v. 30 n. 1 (2013); 177-1902175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2013v30n1p177/24492Silva, Osmar Henrique Moura daUrbano, AlexandreLaburú, Carlos Eduardoinfo:eu-repo/semantics/openAccess2018-03-16T09:32:32Zoai:periodicos.ufsc.br:article/27084Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2018-03-16T09:32:32Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false
