Problems solved by technology

[0005] The present invention is aimed at the current middle school physics teaching, when it comes to the DC motor part, teachers often can only rely on graphic descriptions, so that students cannot understand its principle and structure well, let alone improve the enthusiasm for class, if teaching models such as wooden models are used At the same time, it is inconsistent with the description in the textbook, so we designed this invention, so as to achieve the purpose of reducing costs and environmental protection

Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0015] Such as figure 1 As shown, a single-turn DC motor is divided into a stator part, a rotor part, a brush 6, a bearing plate 7, a bracket 8, a base 9, and a battery, and the stator part is a U-shaped part placed on a bracket 5 The magnet 4 has a distance of 100mm between the inner blocks of its magnetic distance, and the rotor part includes an armature wire frame 3, a rectifier 2 and a rotating shaft 1. The armature wire frame 3 is formed by bending hard wires that can be found in schools, and its shape is a rectangular wire frame, which is connected to the rectifier 2 through the rotating shaft 1 . The rectifier 2 is composed of a small piece of small log, and its outer layer is wrapped with two pieces of metal rectifiers, which serve as t...

Abstract

The invention discloses a teaching type single-turn electromotor. Just like a common electromotor, the teaching model comprises a stator part and a rotor part, wherein the stator part is a magnet, and the armature of the rotor part is formed by bending a conductor; and the rotor part is connected with a rectifier through a rotating shaft. When the electromotor is electrified, a metal rectiblock is in contact with an electric brush so as to ensure that the current in an armature coil is always in one direction, so that the electromotor can continuously rotate, thereby displaying a working principle of a direct-current electromotor. The invention aims to solve the awkward situation that a teacher can not display a model related to an alternating-current electromotor to introduce the working principle of the electromotor to the students in a physical class in middle schools at present.

Description

Technical field: [0001] The invention relates to a motor, in particular to a teaching-type single-turn motor model. Background technique: [0002] DC motors are currently one of the most used motors in the world. This is because, when the DC motor is used, the speed regulation performance is good and the starting torque is large. The so-called "speed regulation performance" means that the motor can artificially change the speed of the motor according to the needs under a certain load condition. The DC motor can realize uniform and smooth stepless speed regulation under heavy load conditions, and the speed regulation range is wide. The high starting torque means that speed regulation can be achieved evenly and economically. Therefore, all machinery that starts under heavy load or requires uniform speed adjustment, such as large reversible rolling mills, hoists, electric locomotives, trams, etc., are driven by DC motors. [0003] The application principle of the DC motor i...
