Abstract
The invention relates to turbofan with magnetic-type and optical coder mechanism.Periphery main up and down or auxiliary splint at fan is provided with two utmost points or many magnet, magnetic quantity transducer is set to detect the revolution of fan near this magnet; Or, on the straight line of die holder in the place, loophole is set at least in the end of main or auxiliary splint, and a side of this loophole light-emitting component is set, then connect light component the opposing party by the fixed disc setting.Running shaft with motor is a rotary coder shaft, is that disk detects the fan revolution with clamping plate, and with feedback signal this is controlled.When constituting fan, directly code device is installed on wherein.
Description
The invention relates to for detecting or Spin Control with the main revolution of rotating to be of fan, have the exploitation of the turbofan of code device, its purpose is not to be provided with original formal absolute coding device, and when constituting fan, integrally encoder is packed into fan, reasonably make the encoder fan, the fan of original complexity is oversimplified, reducing production costs, thereby obtain mass-produced encoder turbofan.
Now with reference to the accompanying drawings an embodiment is illustrated, at up and down discoideus main clamp board (1) and have a blade sheet of most pieces of packing between the auxiliary splint (2) of central opening, central part at main clamp board, be fixed with in the turbofan of nave boss, as shown in Figure 1, load onto magnet (5) in the outside of auxiliary splint (2), for this magnet, the magnetic quantity transducer (6) of closely packing into, among Fig. 3, in last die holder (1), (2) the identical outside, same position in a straight line are provided with the loophole (7) of suitable size, (7), the light-emitting component (8) of the side by this loophole, with the disk that is fixed in an other side (9), photo detector (10) is set, and as rotary coder shaft, and the fan clamping plate have constituted present embodiment as rotating disk up and down with the running shaft (11) of motor M.
The present invention as mentioned above, with original different in the practice that has on the fan of motor in addition the encoder apparatus be combined into that will make, but when the formation motor directly links fan, code device is packed into, therefore, be provided with any differently, very simple with original in assembling work, its make efficiency is quite reasonable.; when making, at first, in the situation of magnetic encoder; as shown in Figure 1; circumference (also can below below the main clamp board) of auxiliary splint (2) top is loaded onto two magnet (5), also multi-pole magnet SN can be set, and magnet closely is provided with sensor (6) hereto; therefore; shown in the Block Diagram of Fig. 5, by the revolution of sensor fan, and by feedback signal to control.And for example shown in Figure 4, in optical encoder, the outer circumferential side at major-minor clamping plate up and down is provided with loophole (7), side up and down at this loophole is provided with light-emitting component (8), by fixed disc, photo detector (10) is set, the opposing party with the encoder of this so-called optical profile type, receive desired light by loophole (7), thereby detect the revolution of fan, and be rotated control by feedback signal, this program is shown in the Block Diagram of Fig. 5.
Accompanying drawing is the expression embodiments of the invention, and Fig. 1 is the planimetric map of turbofan, and Fig. 2 is the same front elevation, expression magnetic encoder mechanism, Fig. 3 is the planimetric map of the demifacet of turbofan, Fig. 4 is its sectional view, be the skeleton diagram of expression optical coder mechanism, Fig. 5 is a Block Diagram.
Claims (1)
- A kind of turbofan with code device of magnetic-type and optical profile type, it is characterized in that 2 utmost points or multi-pole magnet being set at the main clamp board up and down that constitutes turbofan or the outer circumferential side of auxiliary splint, for this magnet magnetic quantity transducer is set closely, by the revolution of this magnetic quantity transducer with the detection fan, or in the end of main clamp board or auxiliary splint, minimum on the straight line of die holder on the place, the loophole of suitable size is set, side for this loophole, light-emitting component is set, by fixed disc photo detector is set the opposing party, running shaft with motor is a rotary coder shaft, and is rotating disk with clamping plate, to detect the revolution of fan, and this is controlled, and directly code device is fit in the fan with feedback signal.
