Embodiment 1

[0013] see figure 1 and figure 2 , This small-power permanent magnet motor drag teaching experiment platform includes motor control core board (1), generator control core board (2), motor inverter power board (3), generator inverter power board (4 ), motor (5), generator (6), rectifier (7) and circuit breaker (8). It is characterized in that each component (1, 2, 3, 4, 5, 6, 7, 8) of the experiment platform is fixed inside the experiment box.

[0014] The various components are connected by wires or pins as follows:

[0015] The motor control core board (1) is connected to the motor inverter power board (3) through pins, and the motor inverter power board (3) is connected to the motor (5); the motor control core board (1) is connected to the motor inverter The power boards (3) are powered by the rectification device (7);

[0016] The generator control core board (2) is connected to the generator inverter power board (4) through pins, and the motor inverter power board (4)...

Embodiment 2

[0020] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0021] The teaching and experiment platform is small in size, with a total weight of no more than 10 kg, and has the characteristics of portability. The power supply voltage of the inverter power boards (3, 4) and the control core boards (1, 2) does not exceed 36V, and has safety features. The permanent magnet synchronous motor PMSM is two permanent magnet synchronous low-power motors, each of which has a power of no more than 100W, has a photoelectric encoder and a Hall position sensor, and can output optical encoder signals and Hall signals.

Embodiment 3

[0023] This embodiment is basically the same as Embodiment 1, combining figure 1 The details are as follows:

[0024] exist figure 1 Among them, the control core board (1, 2) and the inverter power board (3, 4) are pluggable, and the inverter power board can be externally connected to a permanent magnet synchronous motor PMSM, a brushless DC motor BLDC, and a resistive inductive load. In addition, the inverter power board adopts the intelligent power module IPM, including six IGBTs, six anti-parallel diodes, protection, drive, alarm circuits, etc. In addition, the inverter power board also contains an incremental photoelectric encoder interface, Three-way Hall interface, with 2*20P interface, connected to the control core board. The inverter power board can withstand a maximum DC voltage of 50V and a maximum instantaneous current of 5A. In addition, there are hardware protections, which are divided into four aspects: overcurrent (instantaneous current exceeds 5A, automatic ...

Abstract

The invention relates to an experiment box for teaching with all parts fixed inside. The experiment box comprises the following main parts: a power generator control core board, a motor control core board, a power generator inverter power board, a motor inverter power board, a motor A-phase ampere meter, a circuit breaker, a power generator, a motor and a rectifying device. The experiment box is asuitcase with a closed cover, thus being safe and portable. Through the experiment box, the similar experiment that a computer controls the motor to run can be conveniently realized, and thus students are assisted in well understanding the experiment phenomenon and result relevant to the motor. The problem that in the prior art, the experiment can not be carried out conveniently due to the largesize of the motor is solved.

Description

technical field [0001] The invention belongs to teaching instruments, and is a small-power permanent magnet motor drag teaching experiment platform, which is applied to the motor control experiment of automation teaching in colleges and universities, and belongs to the field of teaching research equipment. Background technique [0002] At present, in various education colleges and universities, the teaching of courses such as motor drive and motion control system is involved in the training process of students majoring in automation. Especially for students in the direction of motors, they need to often contact actual motors to understand their operation. Principle, and then carry out related research and operation, so there is a kind of motor experiment box, which can realize some functions. However, most of the experimental boxes that have been released are some large motors that are not easy for students to study at ordinary times. It is very troublesome to use, and most ...
