電動機用の始動システム
Document Type and Number:
Japanese Patent JP4749543
Kind Code:
B2
Abstract:
A starting system for an electric motor having a main coil and an auxiliary coil which are supplied current by an electric current source in which a switch is connected between the electric current source and the auxiliary coil that has an open condition, in which the auxiliary coil remains de-energized by the electric current, and a closed condition for energization of the auxiliary coil with the electric current. An actuating system is positioned relative to the electric motor to receive the magnetic field produced by the motor main coil upon its energization by the electric current for operation of the electric motor that operates to close the switch in response to the magnetic field produced by the current passing through the motor main coil with an intensity above a determined minimum value, and opens the switch when the current through the main coil produces a magnetic field having an intensity of the determined minimum value.
