Abstract

The invention discloses a novel high-speed brushless motor. The novel high-speed brushless motor is characterized by comprising a machine case (1), a stator core (5), a shaft core (6), a magnetic shoe shaft sleeve (8) and a whole magnetic shoe (12), wherein the magnetic shoe shaft sleeve (8) is arranged on the shaft core (6); the whole magnetic shoe (12) is arranged at the outer side of the magnetic shoe shaft sleeve (8); the stator core (5) is arranged at the outer side of the magnetic shoe shaft sleeve (8); the machine shell (1) is arranged at the outer side of the stator core (5); and a rear end cover (18) is arranged at the tail end of the machine case (1). The high-speed brushless motor disclosed by the invention reaches a good silent effect, and is mainly applied to household appliance products, such as an electric hair cutter and an automatic curtain machine.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a novel brushless high-speed motor. Background technique [0002] As people have higher and higher requirements on the noise of electrical appliances, a DC motor is needed on the roller blind machine of automatic curtains, which can obtain smaller decibels and provide users with a quiet and comfortable environment. [0003] The quietness, stepless speed regulation, and large starting torque of automatic curtain machines on the market have become the main parameters of motor design. Satisfying these three requirements is one of the main points of the present invention. [0004] The automatic curtain machine is mainly used in the market as a brushed DC motor. The biggest disadvantage of this product is the friction noise between the carbon brush and the commutator. At the same time, the life of the motor is limited due to the wear and tear of the carbon brushes. [0005] Because ...
