Abstract (en)
The present invention relates to a high speed electromagnetic actuator (1), particularly for selection devices in knitting machines for hosiery and the like. The actuator (1) comprises a frame (2) oscillably supporting a lever (3) having a portion pivotally connected to the frame (2) and at least one electromagnet (4,5) which acts on the lever (3), to cause oscillation thereof; the lever (3) has at least one ledge (12,13) made of ferromagnetic material which extends in the direction of the nucleus (7,8) of the electromagnet (4,5). A synthetic, anti-wear, anti-magnetic material (20) is moulded at least on the reciprocally facing portions of the cited ledge (12,13) and the nucleus (7,8) of the electromagnet (4,5).
