Abstract

A brush-less motor is disclosed, comprising a stator, a rotor, a plurality of field-effect tubes, a commutation circuit board, a control circuit board and a motor end cap, wherein the motor end cap comprises a front end cap and a rear end cap which are mutually fixedly connected to form an integrated motor; the plurality of field-effect tubes is directly fixed at the motor front end cap; the commutation circuit board and the control circuit board are both connected to the motor front end cap. The field-effect tubes of the brush-less motor are directly installed on a housing of the motor, ensuring good heat dissipation, saving heat sinks and cost; the integrated brush-less motor runs more smoothly and imposes requirements which are not as high as those imposed by the split brush-less motor on the accuracy of the housing. Thus, the reject ratio of products during batch production is reduced.
