Description

Brushless motor of sectional type casing Technical Field The utility model relates to the technical field of brushless motors, in particular to a brushless motor with a sectional shell. Background As is well known, a brushless dc motor is composed of a motor body and a driver, and is a typical electromechanical integrated product. Because the brushless DC motor operates in a self-control mode, a starting winding is not additionally arranged on a rotor like a synchronous motor which is started under heavy load under variable frequency speed regulation, and oscillation and step-out can not be generated when the load is suddenly changed. Therefore, brushless motors are used in various large electric devices, particularly in daily electric devices such as blowers and cleaners. In order to apply the brushless motor in the blower or the dust collector, an impeller is arranged on the structure, and a guide plate is arranged in the shell to increase the wind pressure blown out by the impeller. However, the existing brushless motor has a shell body which is an integrated cylinder body, the guide plate is arranged between the cylinder body and the stator support and is integrated with the cylinder body, namely, the guide plate needs to be integrally prepared with the cylinder body, so that the guide plates at the upper half part and the lower half part of the cylinder body can only be made into a shape, such as inclination or arc shape or verticality, but in practical application, corresponding customized design cannot be achieved according to different requirements, such as the lower half part vertical guide, the upper half part arc guide, or the upper half part vertical guide, the lower half part arc guide, or the lower half part vertical guide and the upper half part inclined guide, so that the existing brushless motor is difficult to flexibly match in assembly production. Disclosure of utility model In view of the foregoing deficiencies in the prior art, an object of the present utility model is to provide a brushless motor with a segmented housing.
