Abstract: The invention relates to a connection device, without electrical contact, between a source and a load in order to transmit AC electrical power having a frequency below 2 kHz and at least one phase, the device comprising two parts being able to be separated and assembled at will in a particular configuration suitable for transferring power without electrical contact, a primary part (P1) intended to be connected to the source, and a secondary part (P2) intended to be connected to the load. The invention is such that, once assembled, the two parts form a structure similar to the structure of an asynchronous or synchronous three-phase stator/rotor motor.
