Abstract
Disclosed in the utility model is an outlet structure of a motor. The structure comprises a housing, end covers, stator iron cores, stator windings and external leads. The stator windings are wound on the stator iron cores; the stator iron cores and the housing are installed and connected together; the end covers are installed at two ends of the housing; and the external leads are connected with the wire ends of the stator windings to form connection joint portions. A plurality of bosses are protruded from the end covers; and through holes are arranged in the middle of the bosses. Bushings are embedded into the through holes and are sleeved on the bosses; and the bushings are wrapped on the connection joint portions; and the external leads are led out from the through holes. The provided structure has advantages of simple structure, a few parts, small size, low cost and high assembling efficiency.
