Embodiment Construction

[0027] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0028] A brushless direct current motor demonstration teaching aid comprises a motor display part 1, a drive display part 2, and a control chip. Both the motor display part 1 and the drive display part 2 are fixedly arranged on the demonstration board 3, so that the user can carry the teaching aid. The motor display part 1 includes a stator 11 and a rotor 12 . The stator 11 includes six stator coils, and the stator coils are arranged in a honeycomb shape to form a stator winding. Wherein, two opposing stator coils form a group, and the stator 11 has three groups A, B and C in total. The rotor 12 is composed of 4 permanent magnets. Wherein, the magnetic poles of the two opposite permanent magnets are the same, and the ma...

Abstract

The invention relates to the technical field of teaching equipment, in particular to a brushless direct current motor demonstration teaching aid, which comprises a motor display part, a driving display part and a control chip, wherein the motor display part comprises a stator, a rotor and a first position sensor; the rotor is provided with a marker corresponding to the magnetic pole of the rotor,and the stator is provided with a display window corresponding to the marker; the first position sensor is used for acquiring position information of a rotating shaft of the rotor; the driving displaypart comprises a driving circuit and an indicating lamp; the driving circuit is electrically connected with the stator, the rotor and the indicating lamp; and the control chip is used for controllingthe driving circuit according to the position information. A brushless direct current motor in the prior art is integrally designed and is inconvenient for teaching display. Compared with the prior art, the motor display part and the driving display part clearly display the running state of the motor and the running state of the driving circuit, so that the running principle of the motor is better displayed.
