Abstract
The invention relates to a device meant for checking the rotation direction in asynchronous motors or micromotors. According to the invention, the device consists of an electrically insulated handle (1) made up of a transparent material, provided at one end with a cylindrical cavity (a) accommodating a liquid rotor consisting of mercury (2), the cavity end being covered with a lid (3) provided on the centre with an axle (4) having a helical channel (b) which, will determine the displacement of the liquid rotor in one end of the cavity depending on the rotation direction of the rotating stator field.
