Stepping motor training device

Abstract

To provide a training device integrating basic characteristic of a stepping motor in one board and having an input / output terminal as a device satisfying contents shown in claims in the basic characteristic of the stepping motor.SOLUTION: A stepping motor and a trapezoidal screw (lead screw) are connected by coupling, and movement quantity on the trapezoidal screw can be quantified and measured according to excitation setting of the stepping motor by a position detection needle. With respect to an excitation system, 1 phase, 2 phases, and 1-2 phases can be switched, and a duty ratio can be switched to 100%, 50%. The number of times of pressing a JOG button is counted and can be measured as a movement distance according to a target pulse number. Also, an output terminal of each phase is provided and a pulse waveform can be measured by a data logger or the like.SELECTED DRAWING: Figure 2

Description

Technical Field

[0001] The present invention is a device capable of numerically representing the characteristics of a stepping motor as the amount of movement of a needle attached to the tip of a nut intervening in a lead screw for each excitation method.

Background Art

[0002] In machines that require precise movement, a stepping motor is an indispensable power source. However, there is no training device in industrial high schools, junior colleges, or general education courses at science and engineering universities that can teach the items listed in the claims of the present invention, and it is the only device capable of visualizing and learning the characteristics of a stepping motor.

Summary of the Invention

Problems to be Solved by the Invention

[0003] By using the present invention, the excitation state of a stepping motor can be visualized, and the differences in basic characteristics due to differences in excitation between single-phase, two-phase, and 1-2 phase can be quantified by the moving distance of the lead screw.

Means for Solving the Problems

[0004] Using a control microcomputer in a control box (Figure 2), the device is controlled by a program (Figure 3) that satisfies all the specifications in the claims.
