Hace dos a\u00f1os atr\u00e1s sub\u00ed un video ense\u00f1ando a como controlar un motor de corriente continua. Sin embargo, dicho circuito tenia varios inconvenientes. 1), El circuito solo estaba montado en un protoboard. 2) El cambio de la inversi\u00f3n de giro era muy brusco. 3) La velocidad no se controlaba eficientemente. Por \u00faltimo, solo soportaba una cantidad limitada de corriente. Viendo todos estos inconvenientes, en este episodio crearemos una tarjeta PCB capaz de controlar un motor de 24VDC con un consumo hasta de 15A. la inversi\u00f3n de giro se realizar\u00e1 progresivamente “no bruscamente”. Finalmente, tendremos una variaci\u00f3n de velocidad eficiente.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div><\/div><\/div><\/div><\/section>
