"Set of control system of induction motor and an induction motor, the control system of induction motor, control method of induction motor and the compressor.Describes a set of control system (1) of induction motor (10), and an induction motor (10), a control system of induction motor (10), a control method of induction motor (10), and a compressor is controlled with an induction motor according to the the teachings of the pr. With this invention, and has as objectives to a set.A system and a method where it is possible to operate the engine (10) in a wide range of values of the supply voltage (V ~ Ca ~) of feeding, with a form of adjustment of a voltage controlled (V ~ C ~) which enables the correction of the voltage applied depending on the frequency of the network (F ~ Ca ~).The objectives of this invention are achieved through a set of control system (1) of induction motor (10) and induction motor (10), the induction motor (10) having a rated voltage of operation (V ~ nm ~), the control system (1) comprising a unit. Processame No central (8) that modulates the level of grid voltage (V ~ Ca ~) to a level of the voltage controlled (V ~ C ~)The voltage controlled (V ~ C ~) being applied to the induction motor (10), the grid voltage (V ~ Ca ~) floating from a minimum voltage network (V ~ AC - min ~), the grid voltage (V ~ Ca ~) having a frequency of the network (F ~ Ca ~), and the induction motor (10) having a rated voltage of operation. (V ~ nm ~) and a nominal frequency of operation (F ~ nm ~)The induction motor (10) having a rated voltage of operation (V ~ nm ~) below the value of the grid voltage minimum (V ~ AC - min ~), the processing unit (8) by measuring the frequency of the network (F ~ Ca ~), and when there is a difference between the frequency of the network (F ~ Ca ~) and the nominal frequency of OP Erau00e7u00e3o (F ~ nm ~), the processing unit (8) sets a value of a nominal voltage is changed (V ~ nm to ~)The nominal voltage is changed (V ~ nm ~) being applied to the induction motor (10), and when the frequency of the network (F ~ Ca ~) is equal to the frequency of the network (F ~ Ca ~), the processing unit changes the value of the controlled voltage (V ~ C ~) the level of the nominal voltage (V ~ nm ~).They are also provided for a control system (1), a control method of the system object of the present invention, as well as a compressor driven by an engine (10) comprising the system (1), object of the present invention.
