Abstract

The invention relates to electrical engineering, in particular to linear stepper motors, and can be used for the translational movement of a moving element in a plane. The goal is to increase the stroke on one of the coordinates. The device contains two stationary ferromagnetic gear guides 1 and 2, measles 3, 4 and 6, 7, which are movably fixed on the guides. Anchors 3 4 and 6, .7 are rigidly connected in pairs with each other by rods 5 and 8, respectively. The carriage 9 is movably mounted on the rods 5 and 8 of the engine Korea. The magnitude of the motor stroke along the guide is practically unlimited, since guides 1 and 2 can be made of any length. 3 il. CL 4 el 00 SP 4 00 9uf.1

Description

The invention relates to electrical engineering, to linear stepper motors, and can be used for the translational movement of a movable element in a plane.

The aim of the invention is to increase the stroke along one of the coordinates.

FIG. 1 shows the proposed electric motor, a plan view; in fig. 2 and 3 is a diagram of the movement of the carriage in the direction of the guides.

The two-axis linear stepper motor contains two stationary parallel gear rails 1 and 2, made of a ferromagnetic material, the first pair of cores 3 and 4, equipped with toothed polos and control windings (not shown) connected to each other with a stick 5, with a second pair Korea 6 and 7 with gear poles and windings and controls connected to each other with a stick bar 8 and carriage 9. Anchors, 4 and 6, 7 are equipped with supports (for example, rolling bearings) ensuring their movable fastening on guides 1 and 2. Caret It is also provided with supports ensuring its mobile fastening on the rods 5 and 8. The anchors are connected to the engine control unit of the gibrsimi by the current leads 10 and 11.

The proposed engine works as follows.

The supply to the control windings of each core of a multi-phase alternating voltage supply causes the appearance of a traveling magnetic core, the interaction of which with a gear guide leads to the generation of tractive effort. In this case, measles begins to move in the direction of movement of the traveling magnetic field. Anchors 3 and 4 are controlled synchronously, simultaneously moving in one direction or another. Measles 6 and 7 simultaneously move simultaneously. Moving carriage 9 in the longitudinal direction (direction

Orientation 1 (and guides 1 and 2) is carried out by simultaneously moving all cores 3, 4, 6 and 7 in one direction. The lateral movement of the carriage occurs when the movement of korea 3 and 4 in one, and korea 6 and 7 in another direction. So when moving korea 3 and 4 to the right, and korea 6 and 7 to the left, the carriage 9 moves in the direction of the guide 1 (fig. 2), the movement of korea 3 and 4 has the water, and korea 6 and 7 to the right moves the carriage 9 towards the guide 2 (fig. 3). At unequal speeds of movement of Koras 3, 4 and 6, 7, the carriage 9 is moving along any given trajectory.

Due to the location of all the engine cores on the two fixed parallel gear guides, the stroke of the engine along the guide turns out to be virtually unlimited, since the guides can be made of any desired length. As a result, the absence of movable gear traverse motor has a relatively small mass of moving parts and high speed ...
