Abstract

PURPOSE:To facilitate a mass production by cylindrically winding a strip electromagnetic steel plate formed with many grooves and mounting them on the cylinder of a magnetic material. CONSTITUTION:A groove portion 15 which extends in a widthwise direction at the prescribed pitch toward the lengthwise direction is formed on an electromagnetic steel plate 16 which has a thin rectangular shape and high magnetic permeability. This is wound in a widthwise direction in a cylindrical shape, thereby forming the inner periphery 17 of a stator. The inner periphery 17 is covered on the inner periphery of the cylinder 18 of a magnetic material, thereby forming a cylindrical stator. The portion of the groove portion 15 formed on the plate 16 becomes the grooves the poles, and the other portion becomes a toothed portion. Accordingly, the stator of a cylindrical linear stepping motor can be readily manufactured.

In particular, in a cylindrical linear stepping motor, the air gap between the stator 1 and the slider 14 is uniformly distributed in the radial direction with the support shaft 4 as the center. Since the attractive force is canceled at the center of the support shaft 4, there is no unnecessary side pull, which is highly efficient and produces less vibration and noise than an enclosed linear stepping motor.On the other hand, the structure of the stator 1 However, since the structure is not suitable for mass production, it tends to be expensive.
