Abstract

A novel intelligent control direct-current brushless electric pick comprises a rear-end handle, a brushless motor controller, a direct-current brushless motor, a speed reducing transmission mechanism, a rear end cover, a front-end handle, a shell and a front-end cover. The speed reducing transmission mechanism comprises a gear I, a gear II and a gear III. The direct-current brushless motor comprises a spring washer, a transmission shaft, a rotor, a stator, a bearing I, a bearing II and a cooling fan. According to the novel intelligent control direct-current brushless electric pick, the direct-current brushless motor is adopted, a non-Hall mode is adopted as the control mode, the brushless motor controller is of a full-potting integrated structure, a brushless driving PCB is reinforced on the brushless motor controller through potting adhesives with superior heat conduction performance, and therefore very good vibration resistance is achieved. The service life of the electric pick is greatly prolonged, the novel intelligent control direct-current brushless electric pick is free of maintenance, the reliability is improved, the efficiency of the direct-current brushless motor is high and the energy saving effect is achieved.

Description

technical field [0001] The invention relates to an electric pick, in particular to a novel intelligent control DC brushless electric pick. Background technique [0002] At present, the electric pick is a double-insulated hand-held electric tool powered by a single-phase series-excited motor. It is safe, reliable, and easy to operate. It is widely used in construction, railway construction, and reinforcement industries. However, because the traditional electric pick uses a series-excited motor, its brushes are consumables. Once worn to the limit, various failures may occur in the motor. The life of an electric pick is only a few hundred hours, which is short and difficult to maintain. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of intelligently controlled DC brushless electric pick, so as to solve the above...
