摘要： An electric motor includes a rotor having a stack of laminations positioned axially relative to one another. The stack of laminations includes a first rotor lamination that is divided into a first portion and a second portion. The first rotor lamination is configured to have an asymmetric mass distribution such that the first portion has a first mass and the second portion has a second mass, with the first mass being different from the second mass. The electric motor is configured to selectively generate an unbalanced force during operation (i.e., when the rotor is spinning). The electric motor may include a stator configured to have an asymmetric magnetic field distribution. The electric motor may be employed in a haptic assembly and eliminates the need for a separate eccentric mass to generate a haptic signal.

摘要： An ion separator water pump is provided, comprising a stator cylinder with input and output ports, homopolar north poles, and homopolar south poles, a drive shaft, a rotor core, and seals. Salt water pumped through the ion separator water pumps is desalinated by alternatively flushing out the positive and negative ions at various points as the water flows through the proposed devices. Two pump configurations are presented for use in desalination of salt water.
