Abstract
A thin-plate motor includes a motor shell and a driving device. The driving device is disposed in the motor shell, and the driving device includes a stator structure and a rotor structure. The rotor structure is disposed corresponding to the stator structure. The rotor structure includes a rotor shell and a magnetic structure. The magnetic structure is disposed on an inner wall of the rotor shell. The stator magnetic pole group magnetically drives the magnetic structure as well as the rotor shell to rotate. At least one notch is provided along an inner wall of the base body in an axial direction.
Claims20
A thin-plate motor, comprising:
- a motor shell;
- and
- a driving device disposed in the motor shell, the driving device comprising:
- a stator structure comprising a stator magnetic pole group and a base body, wherein the base body is connected to the motor shell, and the stator magnetic pole group is disposed on an outer periphery of the base body;
- and
- a rotor structure disposed corresponding to the stator structure, wherein the rotor structure comprises:
- a rotor shell comprising a top plate, an outer sidewall and an oil seal, wherein a center of the rotor shell is formed with a cylindrical shaft, one end of the shaft penetrates into the base body, the oil seal is disposed on the rotor shell and surrounds a periphery of the shaft, and
- a magnetic structure disposed on an inner wall of the rotor shell, wherein the stator magnetic pole group magnetically drives the magnetic structure as well as the rotor shell to rotate,
- wherein at least one notch is provided along an inner wall of the base body in an axial direction.
A thin-plate motor, comprising:
- a motor shell;
- and
- a driving device disposed in the motor shell, the driving device comprising:
- a stator structure comprising a stator magnetic pole group and a base body, wherein the base body is connected to the motor shell, and the stator magnetic pole group is disposed on an outer periphery of the base body;
- and
- a rotor structure disposed corresponding to the stator structure, wherein the rotor structure comprises:
- a rotor shell comprising a top plate, an outer sidewall and an oil seal, wherein a center of the rotor shell is formed with a cylindrical shaft, one end of the shaft penetrates into the base body, the oil seal is disposed on the rotor shell and surrounds a periphery of the shaft;
- and
- a magnetic structure disposed on an inner wall of the rotor shell, wherein the stator magnetic pole group magnetically drives the magnetic structure as well as the rotor shell to rotate,
- wherein a wear-resistant piece is arranged at an inner bottom of the base body to abut against the shaft, and the wear-resistant piece is partially removed from an outer peripheral edge to form at least one notch.
