A METHOD FOR CONTROLLING AND PROTECTING ELECTRIC MOTORS, A SYSTEM FOR CONTROLLING ELECTRIC MOTORS AND AN ELECTRIC MOTOR SYSTEM

摘要

Invention patent: b '' method of control and protection of electric motors, the control system of electric motor and system of electric motor '' d .Describes a method of control and protection of electric motors 10 equipped with the rotor.In particular, the permanent magnet motors operated electronically by a control system 2 comprising a three-phase bridge investor 5.Characterized by understanding a step of counting a first period of time during which the said must be between an original position and the next position and a step count of a socialThe world period of time subsequ00b3ente to said first period of time, during which the said rotor must pass by the next position.The present invention translates in a control system 2 of electric motor 10 with the rotor, in particular a motor permanent magnet.A three-phase bridge compreedendendo investor 5 and characterized by additionally comprise a microcontroller capable of analyzing the positions of the rotor as a function of time.Associated with a counter capable of effecting a step of counting a first period of time during which the said rotor must be between an original position and the next position and a step of COntagem for a second period of time subsequ00b3ente to said first period of time, during which the said must pass by the next position.As well as a system of electric motor 1 comprising a control system 2, an electric motor 10 electronically triggered by the control system 2.And characterized by additionally comprise a microcontroller capable of analyzing the positions of the rotor as a function of time.Associated with a counter capable of effecting a step of counting a first period of time during which the said rotor must be between an original position and the next position and a step of CONtagem for a second period of time subsequ00b3ente to said first period of time, during which the said rotor must pass by the next position.
