Abstract
"MOTORES ELéTRICOS UNIVERSAIS DE DUAS BOBINAS NO CIRCUITO ELéTRICO DO ESTATOR COM APERFEIçOAMENTO PARA ACIONAMENTO E OBTENçãO DE CINCO VELOCIDADES DE ROTAçõES". Patente de Modelo de Utilidade que é compreendido por um motor elétrico universal (1) confeccionado com duas bobinas (6 e 7) no estator (1 8) sendo que as extremidades (8, 9 e 10, 11) das respectivas bobinas (6 e 7) estando ligadas, a extremidade (5) da escova (3), ao cordão de alimentação de energia (15) e aos contatos de uma chave de múltiplos pólos (12) na qual estão conectados três diodos (13, 14 e 21) que por meio deste conjunto de componentes e com a adição do diodo (21) em uma posição adicional na chave (12) permitir se obter do modelo existente de quatro, três ou duas velocidades uma quinta velocidade de rotação distinta para esse tipo de motor, conforme o número de pólos da chave (12) e da maneira como são efetuadas ligações dos diodos (13, 14 e 21) e das extremidades das bobinas (6 e 7) na chave de acionamento (12) com contatos móveis deslizantes (20) conectados."TWO-COIL UNIVERSAL ELECTRIC MOTORS IN THE STATOR ELECTRIC CIRCUIT WITH IMPROVEMENT FOR DRIVING AND OBTAINING FIVE ROTATION SPEEDS". Utility Model Patent which comprises a universal electric motor (1) made with two coils (6 and 7) in the stator (18) with the ends (8, 9 and 10, 11) of the respective coils (6 and 7) being connected, the end (5) of the brush (3), to the power supply cord (15) and to the contacts of a multi-pole switch (12) to which three diodes (13, 14 and 21) are connected. whereas by means of this set of components and the addition of diode (21) in an additional position on switch (12), the fifth, three or two speed model can be obtained with a distinct fifth rotational speed for this type of engine, depending on the number of poles of the switch (12) and how diodes (13, 14 and 21) and coil ends (6 and 7) are connected to the drive switch (12) with sliding movable contacts (20) connected.
