Description

Technical Field

[0001] The utility model relates to a motor, in particular to a dental implant integrated motor. Background Art

[0002] At present, when a dental implant motor is working, it is necessary to control the motor's operating state. The existing control method for dental implant motors is generally to set an integrated control circuit on the back cover of the motor and write the program code to be controlled into the control circuit housing to realize the control of the motor. However, since the hygiene requirements of dental implant motors are relatively high and they need to be sterilized at high temperature after each use, and the motor needs to have a high water release performance when steamed in water at high temperature, the existing sealing method is to seal the tail cap specially used for cleaning with the back cap thread so that the internal components of the control circuit will not come into contact with water vapor. However, the sealing effect of the tail cap thread seal is not good, and the tail cap is easy to lose when not in use, which increases the cost of reconfiguring the tail cap.

The back cover is encapsulated by laser welding and glue filling. Compared with ordinary motors bonded with glue, it is more secure and has stronger sealing, which greatly improves the waterproof ability of the motor. During steam sterilization, water vapor cannot enter the interior of the motor. The electronic components and rotor in the motor are well protected. The stability and steam resistance of the motor are greatly improved, and the reliability is higher.

[0005] The addition of a magnetic sleeve protects the magnets, prevents oxidation, extends their life, secures the balancing weight, improves the rotor's resistance to retort, and ensures proper motor operation. The integrated housing features higher machining precision and eliminates the need for a front cover, making assembly quicker and easier.

[0006] As an improvement to the present invention's integrated dental implant motor, a stator assembly is also housed within the cavity of the integrated housing. The stator assembly comprises a winding cup and a punched sheet. The winding cup is inserted into the punched sheet and is formed by laminating a three-petal diamond-shaped coil winding.

The epoxy resin adhesive also features a water-draining function, allowing for steam cleaning and disinfection of the motor without affecting the internal motor structure.

[0011] As an improvement to the present invention's integrated dental implant motor, a magnetic encoder module is integrated into the integrated PCB. This built-in encoder eliminates the need for motor adjustment, requiring only pre-programming. This makes installation more efficient, while also ensuring more precise motor operation and virtually identical forward and reverse currents.

[0012] As an improvement to the dental implant integrated motor of the present invention, one end of the rotating shaft passing through the through hole is sleeved with a connector, and the front end of the connector is provided with two clamping arms.

[0013] The beneficial effects of the present invention are as follows: the rear cover of the present invention is provided with two mounting cavities, the integrated PCB board is accommodated in the rear cavity, and is sealed with epoxy resin glue to seal the rear cavity. The rear cover and the housing are welded as one body, further enhancing the water-draining effect.
