Description

Single-phase tubular linear motor

The utility model relates to a kind of linear electric motors, in particular for the single-phase cast linear electric motors of the intermittent matched with devices of using in short-term such as electric controller for curtain.

Existing single-phase cast linear electric motors, as Jiangsu Polytechnical College and the test manufacture of Zhengjiang City's irrigation sprinkler factory, be the supporting linear electric motors of LI type orthoscopic electric controller for curtain, its work is made as continuous operation 6 minutes, the connection of each winding of electric motor primary is that two windings, one end of electric motor primary one end is that end of the same name joins and inserts an end of power supply again, each winding end of the same name that is in odd positions and even number position is connected in series respectively, determining and the winding type of attachment of 6 minutes continuous duties, make that the volume of motor is big, weight is also big, efficient is low, its thrust to weight ratio is 6 newton/kg, has brought a lot of troubles for installation and use, has also caused the waste of the raw material and the energy.

The purpose of this utility model provides the single-phase cast linear electric motors that a kind of volume is little, in light weight, efficient is high, is particularly suitable for intermittent in short-term rectilinear motion field of using.

The purpose of this utility model is to realize like this.The external diameter of electric motor primary is φ 45～55mm, and length is 70～120mm, and winding wire diameter is φ 0.19～0.27mm, each umber of turn is 1000～1600 circles, the electric motor primary pole span is 29～32mm, and per tooth is apart from the iron core thick 2.5～4mm of being that changes, and the motor secondary external diameter is φ 14～16mm.The different name end of two windings of electric motor primary one end joins and inserts an end of power supply again, and each winding that is in odd positions and even number position is respectively that end of the same name is connected in series.

The utility model will be further described below in conjunction with accompanying drawing.Accompanying drawing is that electric motor primary winding of the present utility model is arranged winding diagram.Wherein L1～L6 is the electric motor primary winding, and the end of winding L 1 and L2 is that the different name end joins and inserts an end of power supply again, and the other end of winding L 1 is connected with the end of the same name of winding L 3, and the other end of winding L 3 is connected with the end of the same name of winding L 5; Equally, the other end of winding L 2 is connected with the end of the same name of winding L 4, and the other end of winding L 4 is connected with the end of the same name of winding L 5.

The work that the utility model adopts is made as continuous operation 30 times, and (motor secondary is a standard with 2 meters long, 90 seconds running times), thereby the corresponding structural parameters that dwindle linear electric motors of energy, volume is reduced, weight saving, adopt winding connection form of the present utility model that the thrust output of electric motor primary is improved about 1 newton, thrust to weight ratio reaches 20 newton/kg, is fit to very much intermittent in short-term rectilinear motion field of using.

Be embodiment of the present utility model below.

Embodiment 1, the electric motor primary external diameter is φ 48mm, length is 75mm, the motor secondary external diameter is φ 14mm, and the electric motor primary number of windings is 4, and every umber of turn is 1500 circles, line directly is φ 0.021mm, the electric motor primary pole span is 29mm, and the electric motor primary per tooth changes thick in 2.5mm apart from iron core, and the arrangement connection type of electric motor primary winding as shown in drawings.The thrust to weight ratio of motor is 20 newton/kg, and it is 6 newton that output starts thrust.

Embodiment 2, the electric motor primary external diameter is φ 54mm, and length is 110mm, and the motor secondary external diameter is φ 16mm, the elementary number of windings is 6, every umber of turn is 1500 circles, and line directly is φ 0.27mm, and the electric motor primary pole span is 31mm, the electric motor primary per tooth changes thick in 3.5mm apart from iron core, the arrangement connection type of electric motor primary winding as shown in drawings, the thrust to weight ratio of this motor is 20 newton/kg, it is 15 newton that output starts thrust.
