The invention relates to electric machine industry and may be used in drives of reciprocating and in-line motions of manufacturing mechanisms used low and ultra low speeds (in-line motion) of a work member. The proposed differential linear drive consists of two DC drives of inductor type with secondary parts united by means of a common shaft. The secondary part of the first drive is rigidly connected with the shaft, the secondary part of the second drive is connected with the shaft by means of screw-nut or jointed-screw pair, or magnetic screw. The presented version of the differential linear drive based on DC arc-type stator drives of inductor type allows using such devise for mechanism with small value of rating moment and linear motion forces, for example for receive and releasing device of a manufacturing machine for production of fiber-glass cable. |
