Abstract
The utility model discloses a double-frequency hysteresis synchronous motor, which comprises an enclosure. A stator core (6) and an armature winding (7) are arranged in the enclosure (4). A front bearing (3) and a front bearing cap (2) are arranged at the front end of the enclosure (4). A rear end cover (9) is arranged at the rear end of the enclosure (4). A rear bearing (8) is arranged in a bearing hole of the end cover (9). A rear bearing cap (10) fixedly presses the end cover (9) on the enclosure (4) through a bolt. A rotor shaft (1) with a non-magnetic conducting material structure is arranged on the front bearing (3) and the rear bearing (8). A rotor core (5) with a hysteresis material structure is fixed on the rotor shaft (1). The double-frequency hysteresis synchronous motor has the advantage of capability of normally working under two different power frequencies, simple structure, wide application range and low manufacture cost and use cost.
Description
Technical field
the utility model relates to a kind of bifrequency hysteresis synchronous motor, belongs to the motor manufacture technology field.
Background technology
are present, and synchronous machine of the prior art generally can only be worked under the power drives under single, the specific frequency, can not be used for the power drives of two kinds of different frequencies.When adopting this motor that is applicable to the single-frequency power supply in running, to have defective because of control or system, can't guarantee motor under its basic frequency during operate as normal, this motor is out of service, thereby system is affected.So the motor of existing this single-frequency work still can not satisfy the needs of use.
Summary of the invention
The purpose of
the utility model is, provide a kind of simple in structure, and can be under two kinds of different electrical power frequencies the bifrequency hysteresis synchronous motor of operate as normal, to overcome the deficiency of prior art.
The technical scheme of
the utility model is to constitute like this: a kind of bifrequency hysteresis synchronous motor of the utility model; Comprise casing; Stator core and armature winding are housed in casing, fore bearing and front bearing retainer are installed, end cap is installed in the rear end of casing at the front end of casing; Rear bearing is installed in the dead eye of end cap; Rear bearing cover presses solidly end cap on casing through bolt, and the armature spindle of non-magnet material structure is installed on fore bearing and rear bearing, and on armature spindle, is fixed with the rotor core of hysteresis material structure.
are provided with the input power connector end that is connected with bifrequency AC power driving governor on above-mentioned armature winding.
The supply frequency of
above-mentioned bifrequency AC power driving governor output that is connected with the input power connector end of armature winding is 120Hz or 80Hz.
Owing to adopted technique scheme, the utility model can be worked under the input power supply of two kinds of different frequencies
.Adopt same the motor of the utility model under the mode of operation of two frequencies, to switch, when this motor operates in main operating frequency (120Hz) process, it is big that the load of system becomes; Step-out appears in motor; When making system's cisco unity malfunction,, make machine operation under task frequency (80Hz) mode of operation through the frequency of Switching power; Reaching increases synchronous torque and locked-rotor torque, makes system works under slow-speed of revolution synchronous operation pattern.Adopt the technical scheme of the utility model, motor can be worked down in two frequencies (rotating speed), the utility model is not changing under motor size, the weight situation, makes motor performance index reach backup, has increased reliability.So, the utility model compared with prior art, the utility model not only have can be under two kinds of different electrical power frequencies the advantage of operate as normal, but also have simple in structure, range of application is wide, cost of manufacture and all low advantage of use cost.

Fig. 1 is the structural representation of the utility model.
Being labeled as in
accompanying drawing: 1-armature spindle, 2-front bearing retainer, 3-fore bearing, 4-casing, 5-rotor core, 6-stator core, 7-armature winding, 7.1-power connector end, 8-rear bearing, 9-end cap, 10-rear bearing cover.
Embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
The embodiment of
the utility model: the structural representation of a kind of bifrequency hysteresis synchronous motor of the utility model is as shown in Figure 1; This motor comprises casing 4; Traditional stator core 6 and armature winding 7 are housed in casing 4, at the front end of casing 4 fore bearing 3 and front bearing retainer 2 are installed, during making; An end cap 9 is installed in rear end at casing 4; Rear bearing 8 is installed in the dead eye of end cap 9, and rear bearing cover 10 is pressed solidly end cap 9 on casing 4 through bolt, on fore bearing 3 and rear bearing 8, install the armature spindle 1 of a non-magnet material structure; Make the employing of armature spindle 1 and can adopt the higher non-magnet material of intensity of the prior art; Like materials such as stainless steel, alloy aluminum, and at the rotor core 5 of fixing the hysteresis material structure on the armature spindle 1, it is the magnetic hysteresis alloy rod making of 2J25 that rotor core 5 preferably adopts model; On armature winding 7, produce the input power connector end 7.1 that can be connected simultaneously with the bifrequency AC power; And when using the utility model, the supply frequency of the bifrequency AC power that will be connected with the input power connector end 7.1 of armature winding 7 is chosen as the bifrequency AC power of 120Hz or 80Hz.
