Abstract
The invention relates to a kind of magneto turning fan with coding metwork.Direct and the fan binding of motor that will have the rotating coder of multiblade fan, the magnetic recording portion of the disc rotating drum that SN magnet alternately is housed is set between motor and fan, the revolution of magnetic quantity transducer with the detection fan is set near this magnetic recording portion, and controls this revolution with feedback signal.And with the running shaft of the above-mentioned rotating drum running shaft as fan, a kind of production process is simple, cost is low thereby provide, and is suitable for mass-produced rotary fan with encoder performance.
Description
The invention relates to the exploitation of magneto turning fan with coding metwork, its purpose is to obtain to be provided with the rotating drum that the NS magnet of alternately configuration forms around the centre of motor and multiblade fan, make the axle of the running shaft of fan, to carry out the magnetic-type rotating coder of speed controlling as rotating coder.
With reference to the accompanying drawings the one example is illustrated, in the multiblade fan (2) that directly links with motor (1), the side of the rotating drum (3) between this motor (1) and this fan (2) is provided with has the magnetic recording portion rotating drum that alternately disposes NS magnetic pole (4), the running shaft of the rotary coder shaft (5) of this revolving cylinder as fan will be provided with, rotating drum in the magnetic recording portion that approaches alternately to have disposed the NS pole magnet is provided with magnetic quantity transducer (6), by this sensor, detect the revolution of fan, and control this revolution with feedback signal, so that the fan with this encoder to be provided.
The present invention and original be provided with in addition having on the fan of motor.The fan difference that encoder apparatus forms, owing to it is characterized in that when constituting fan, the encoder of packing into is therein made, therefore, production process is very simple, only needs fan is combined with motor, just the rotary fan that can obtain to have encoder performance, be suitable for a large amount of productions, and the encoder rotary fan is reduced cost.
Accompanying drawing is expression one embodiment of the invention, and Fig. 1 is the explanatory drawing of the motor direct connection multiblade fan of magnetic-type rotating coder, and Fig. 2 is the front elevation of rotating drum, and Fig. 3 is the control Block Diagram of magnetic encoder.
Claims (1)
- A kind of magneto turning fan with coding metwork, it is characterized in that directly linking in the fan at the motor of encoder with the rotation of control cylindrical fan of multiblade, between motor and fan, the magnetic recording portion of the disc rotating drum that SN magnet alternately is housed is set, magnetic quantity transducer and this magnetic recording portion is approaching, and with the rotary coder shaft of this magnetic recording portion running shaft as fan.
