Abstract
The utility model discloses a cast-aluminum motor rotor. The cast aluminum motor rotor comprises a rotor chip (3) which is composed of rotor pieces, and is characterized in that: one end part of the rotor chip (3) is provided with a cast-aluminum end ring (1), and the cast-aluminum end ring (1) is provided with an annular groove (2) or an annular step (4). By arranging the annular groove or the annular step on the cast-aluminum end ring, the area of the aluminum ring of the cast-aluminum end ring at a notch of the rotor is reduced, and thus the purpose of lowering the starting current by increasing the resistance is realized, and the starting torque is improved; meanwhile, the unchanged sectional area of the cast-aluminum end ring guarantees the rated efficiency of the motor, improves the product performances, and effectively saves energy.
Description
Technical field
The utility model relates to a kind of cast-aluminum motor rotor, particularly a kind of cast-aluminum motor rotor that is applied to washing machine.
Background technology
At present, along with the progress of society, country is increasingly high to the energy-conserving and environment-protective requirement of products.Improve just energy savings greatly of efficiency of motor.But at present a lot of products have the requirement of pair detent torque again.And general capacitor-operated motor is to realize increasing rotor resistance to improve the purpose of detent torque through the height that reduces cast-aluminum rotor end aluminium ring, and the efficient that has still increased the rotor resistance rear motor can reduce greatly.
The utility model content
The purpose of the utility model is, a kind of cast-aluminum motor rotor is provided.The utility model can not only improve starting torque, can guarantee the rated efficiency of motor again.
The technical scheme of the utility model: a kind of cast-aluminum motor rotor, comprise the rotor chip that constitutes by rotor sheet, it is characterized in that: described rotor chip end is provided with the cast aluminium end ring, and the cast aluminium end ring is provided with annular groove or ring-shaped step.
In the aforesaid cast-aluminum motor rotor, described rotor sheet is a silicon steel sheet.
Compared with prior art; Starting current was big and kelvin effect is arranged when the utility model utilized electric motor starting, so the current density at rotor notch place is bigger, through annular groove or ring-shaped step are set on the cast aluminium end ring; Make that the aluminium anchor ring that has dwindled rotor notch place cast aluminium end ring is long-pending; Thereby realize increasing the purpose that resistance reduces starting current, improved starting torque, simultaneously because of the constant rated efficiency that guarantees motor again of cast aluminium end ring sectional area; Improve properties of product, effectively practiced thrift the energy.The utility model also has the characteristics simple in structure and easy to use of implementing.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
Being labeled as in the accompanying drawing: 1-cast aluminium end ring, 2-annular groove, 3-rotor chip, 4-ring-shaped step.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment 1.A kind of cast-aluminum motor rotor constitutes as shown in Figure 1ly, comprises the rotor chip 3 that is made up of rotor sheet punching press stack, and it is characterized in that: described rotor chip 3 ends are provided with cast aluminium end ring 1, and cast aluminium end ring 1 is provided with annular groove 2.Described rotor sheet is a silicon steel sheet.
Embodiment 2.A kind of cast-aluminum motor rotor constitutes as shown in Figure 2ly, comprises the rotor chip 3 that is made up of rotor sheet punching press stack, and it is characterized in that: described rotor chip 3 ends are provided with cast aluminium end ring 1, and cast aluminium end ring 1 is provided with ring-shaped step 4.Described rotor sheet is a silicon steel sheet.
The utility model is through being provided with annular groove or ring-shaped step on the cast aluminium end ring; Make that the aluminium anchor ring that has dwindled rotor notch place cast aluminium end ring is long-pending; Thereby realize increasing the purpose that resistance reduces starting current, improved starting torque, simultaneously because of the constant rated efficiency that guarantees motor again of cast aluminium end ring sectional area; Improve properties of product, effectively practiced thrift the energy.The utility model also has the characteristics simple in structure and easy to use of implementing.
Claims (2)
1. a cast-aluminum motor rotor comprises the rotor chip (3) that is made up of rotor sheet, it is characterized in that: described rotor chip (3) end is provided with cast aluminium end ring (1), and cast aluminium end ring (1) is provided with annular groove (2) or ring-shaped step (4).
2. cast-aluminum motor rotor according to claim 1 is characterized in that: described rotor sheet is a silicon steel sheet.
