Embodiment Construction

[0007] Combine below figure 1 , the present invention is described in further detail.

[0008] refer to figure 1 , a miniature wireless control platform, including a total control platform 10 for transmitting control signals and a micro control module 20 for receiving control signals, the micro control module 20 includes a power supply 21, a microprocessor 22, a micro brushless motor 23 and a shape memory alloy 24, the power supply 21 supplies power to the microprocessor 22, the microprocessor 22 processes the control signal and drives the action of the micro brushless motor 23 and the shape memory alloy 24, and the action of the shape memory alloy 24 realizes the rotor position of the micro brushless motor 23 detection. Shape memory alloy 24 is a new type of functional material. The most important characteristic is the shape memory effect, that is, the shape change of stretching and contraction can be realized according to the change of its own temperature. This stretching...

Abstract

The invention belongs to the technical field of automatic control, and particularly relates to a miniature wireless control platform. The miniature wireless control platform includes a general control platform that transmits a control signal and a miniature control module that receives the control signal, wherein the miniature control module includes a power supply, a microprocessor, a miniature brushless motor and a shape memory alloy, the power supply supplies power to the microprocessor, the microprocessor processes the control signal and drives action of the miniature brushless motor and the shape memory alloy, and the shape memory alloy acts to realize rotor position detection of the miniature brushless motor. The shape memory alloy has a shape memory effect, and can realize shape changes of stretch and contraction according to the temperature of itself, and through replacement of a position sensor with the shape memory alloy, the miniature wireless control platform is simple in structure, small in size and low in cost, and has a relatively long service life at the same time.

Description

technical field [0001] The invention belongs to the technical field of automatic control, in particular to a miniature wireless control platform. Background technique [0002] Brushless DC motors have the advantages of long life, high efficiency, and high stability, and are widely used in households, industries, automobiles, and automation. Compared with brushed motors, brushless motors do not have commutation brushes, and electronic commutation replaces mechanical commutation. The control of the brushless DC motor can be realized by a three-phase inverter with the help of sensors that detect the position of the rotor of the motor. But the position sensor will increase the cost and size of the motor. Therefore, the control method of brushless DC motor with small size and no position sensor is a research hotspot in recent years. Contents of the invention [0003] The purpose of the present invention is to provide a small size wireless control platform. [0004] In order...
