Description
The present invention is a non-contact claw pole magnetic exciting generator.
Up to now, the domestic claw pole magnetic exciting generator of having produced has the contact.It has the some shortcomings part: leakage field is big, and magnetic leakage factor is up to 1.4; Efficient is low, only reaches 50% usually; Slip ring is dynamic the contact with brush, and electric spark is arranged unavoidably, and this has not only increased the workload of safeguarding, but also disturbs radio communication; The characteristic of efficient and rotating speed is softer, can not keep high efficiency in bigger velocity variations scope.The efficient of external non-contact claw pole magnetic exciting generator is also on the low side, the ZFK1010 type of West Germany Siemens (Siemens) company, 3.6KW, this type of electric efficiency only 79% of 1300 rev/mins, the 1.5KW of the Dai Leke-Lei Mi of the U.S. (Delco-Remy) company, 5000 rev/mins similar electric efficiency have only 75%, all fail to solve this problem of minimizing leakage field perfectly.
Task of the present invention provides the high efficiency claw pole electric generator of 0.2KW to 55KW internal magnetic circuit series.
Task of the present invention adopts following measure to finish: adopt the brushless excitation mode, becoming has the contact into contactless; Determine that suitable pawl utmost point shape reduces leakage field; Determine rational main air gap delta
