Title: MOTOR STRUCTURE CAPABLE OF EFFECTIVELY CHANGING LENGTH OF MAGNETIC CIRCUIT
Abstract:
Disclosed is a motor structure which can comprise a shaft (24), a rotor (22) and a stator (21). The rotor (22) can be coupled to the shaft (24), the rotor (22) can comprise a plurality of magnets (221), and the angle between the central axis (MC) of each magnet (221) and the central axis (RC) of the shaft (24) is less than 90 degrees. The stator (21) can drive the rotor (22) to rotate, the stator (21) can comprise a plurality of stator teeth, and the angle between the axis (BC) parallel to the slope of a tooth shoe (211) of each stator tooth and the central axis (RC) of the shaft (24) is less than 90 degrees.
