Embodiment Construction

[0025] A motor device and a motor speed control system according to preferred embodiments of the present invention will be described below with reference to related drawings, wherein the same components will be described with the same component symbols.

[0026] Please refer to figure 2 As shown, it is a schematic block diagram of a motor speed control system disclosed in the present invention. The motor speed control system 2 includes a control device 22, a motor device 24 and a positive coupling between the control device 22 and the motor device 24. A power signal line 261 , a negative power signal line 262 and a feedback / speed control signal line 263 . Therefore, the control device 22 controls the motor device 24, and further enables the motor device 24 to drive the action of the rotating body 242 connected thereto. At the same time, the motor device 24 also feeds back the rotation state of the rotating body 242 to the control device 22, so that the control device 22 can ...

Abstract

The invention discloses a motor device and a motor speed control system. Two power supply signal wires and a feedback / speed control signal line are coupled between a control device and the motor device, wherein the two power supply wires can be used for electrically connecting the control device with the motor device; the feedback / speed control signal wire is used for bilaterally transmitting signals from the control device and the motor device.

Description

[0001] This application is a divisional application of the application with the application date of November 16, 2007 and the application number 200710186726.9 entitled "Motor Device and Motor Speed ​​Control System". technical field [0002] The invention relates to a motor device and a motor speed control system. Background technique [0003] A large number of signal lines with complex connections are usually coupled between the existing control motor device and the control device for controlling its rotation. For example, a common motor device (such as a brushless motor for driving a fan ) motor speed control system such as figure 1 As shown, the positive power signal line 161 and the negative power signal line 162 are coupled between the control device 12 and the motor device 14 so that the control device 12 and the motor device 14 are electrically connected to each other. In addition, the speed control signal line 163 connects the control device 12 The generated speed ...
