Description

Technical Field

[0001] The utility model relates to the technical field of linear Hall brushless motors, in particular to a linear Hall brushless motor. Background Art

[0002] A linear Hall-effect brushless motor is a mechatronic product consisting of a synchronous motor and a drive. It operates based on the Hall effect, using a position sensor to detect the polarity of the motor's rotor. The power electronics and integrated circuits in the drive generate the required number of switching states to drive the motor. This type of motor is commonly used in electric vehicles. The Hall-effect sensor detects rotor position and transmits this information to a brushless controller. The controller, based on these signals, outputs a split-phase voltage to drive the motor.

[0003] Conventional linear Hall brushless motors have an integrated housing and require other equipment to provide heat dissipation during operation. However, their own structure lacks a good heat conduction and dissipation structure, which affects the motor's own operational stability.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a linear Hall brushless motor is proposed. Utility Model Content

[0008] Furthermore, one side surface of the first heat dissipating fin and the second heat dissipating fin are both in contact with the side surface of the shell, and the first heat dissipating fin and the second heat dissipating fin are both installed between the first buffer frame and the second buffer frame.

[0009] Furthermore, the fixing rods horizontally penetrate the upper and lower ends of the second heat dissipating fins respectively, and there are four groups of fixing rods in a circular array with the motor housing as the center.

[0010] Furthermore, the fixing rod is threadedly connected to the motor housing, and the first heat dissipating fin is connected and installed to the motor housing via a bolt structure and has structural detachability.

[0011] Furthermore, the movement includes a shock-absorbing sleeve, a stator, a rotor and a support shaft frame. The stator is installed on the inner wall of the shock-absorbing sleeve, and the rotor is installed in the middle of the stator, and the support shaft frame is installed in the middle of the rotor.

On the other hand, it can ensure that the stator is stably fixed inside the shell, playing a role in structural stability and protection.
