摘要:
An actuator (52) for a personal care appliance (50) comprises a housing (54), a spindle (64), a tangential actuator portion (70), and an axial actuator portion (72). The tangential actuator portion (70) includes first and second magnet and pole assemblies (76,78) that define a tangential spring function of the tangential actuator portion. The axial actuator portion (72) includes third and fourth magnet and pole assemblies (90,92) that define an axial spring function of the axial actuator portion. At least one of (i) the first and second magnet and pole assemblies (76,78) of the tangential actuator portion (70) and (ii) third and fourth magnet and pole assemblies (90,92) of the axial actuator portion are configured to enhance a corresponding spring function of the axial actuator portion or tangential actuator portion, respectively.
