Abstract

sistema e métodos para controlar as operações do motor. são fornecidos o sistema (200) e método (600) para controlar as operações de um motor (114). o método (600) inclui operar (602), por controlador eletrônico (202), motor (114) em um dentre o primeiro modo de operação ou o segundo modo de operação. o primeiro modo de operação é um modo de operação isócrono que facilita o ajuste da velocidade do motor para adequar à velocidade alvo do motor correspondente à alteração na carga do motor de sem carga para carga total. o segundo modo de operação é o modo de operação de queda que facilita a diminuição predefinida na velocidade do motor correspondente à alteração na carga do motor de sem carga para carga total. o controlador eletrônico (202) recebe (604), por meio do interruptor de modo do motor (214), entrada do operador indicando alteração no modo de operação do motor (114) e determina (606) o modo de operação atual do motor (114). o controlador eletrônico (202) controla o motor (114) para alterar o modo de operação com base na entrada do operador recebida e no modo de operação atual determinado do motor (114) e controla a velocidade do motor de acordo com o modo de operação alterado correspondente à alteração na carga do motor.system and methods for controlling engine operations. System (200) and method (600) for controlling the operations of a motor (114) are provided. the method (600) includes operating (602), by electronic controller (202), motor (114) in one of the first mode of operation or the second mode of operation. The first mode of operation is an isochronous mode of operation that facilitates adjustment of engine speed to match the target engine speed corresponding to the change in engine load from no load to full load. The second mode of operation is the drop mode of operation which facilitates the predefined decrease in engine speed corresponding to the change in engine load from no load to full load. the electronic controller (202) receives (604), via the engine mode switch (214), operator input indicating a change in the engine operating mode (114) and determines (606) the current engine operating mode ( 114). the electronic controller (202) controls the motor (114) to change the mode of operation based on the received operator input and the determined current operating mode of the motor (114) and controls the speed of the motor in accordance with the mode of operation changed corresponding to the change in engine load.
