Description
Technical field
The present invention relates to a kind of small household appliance salient pole type single-phase capacitor operation motor more particularly to it is fixed, turns
The design of sub- iron core, in International Patent Classification (IPC), classification belongs to H02K1/08 or H02K1/14.
Background technique
Salient pole type single-phase capacitor operation motor has the advantages that copper consumption is less, since the calculating of its leakage reactance does not have comparison accurate
Calculation formula cause electromagnetic design adjustment difficult so far not than more complete, accurate design method, it is difficult to obtain preferable
Performance.
Summary of the invention
The technical problem to be solved by the present invention is to propose a kind of salient pole type single-phase capacitance suitable for small household appliance
The electromagnetic structure of operation of electrically driven machine can get preferable performance.
The technical solution that the present invention solves the technical problem is a kind of small household appliance salient pole type single-phase capacitance fortune
Turn motor, 15~60W of rated output power, rated slip 0.12 ± 0.05；Its electromagnetic structure includes:
--- stator core stamping sheet is the circumference shape that mm and 4 jiao of rectangular size (108 ± 1) have circular arc, internal diameter
6.7cm, the facewidth such as 8 slots are uniformly distributed, groove profile are as follows: slot opening (BS0) 0.25cm, slot shoulder breadth (BS1) 1.58cm, slot bottom are wide (BS2)
2.24cm, notch height (HS0) 0.07cm, slot shoulder height (HS1) 0.07cm, slot height (HS2) 0.87cm, slot are total high (HS)
1.61cm；
--- the facewidth such as 10 slot of cage rotor are uniformly distributed, groove profile are as follows: slot opening (BR0) 0.08cm, slot shoulder breadth (BR1) 0.6cm,
