Theories of the Linear, Induction Motor and Compensated Linear Induction Motor

IEEE Transactions on Power Apparatus and Systems / Technical Operations Committee, 1972
The paper explains two new theories of the linear induction motor, and indicates that the end effect exercises very adverse influence on motor performances, and proposes the compensated linear induction motor as a measure to eliminate. the end effect.

Linear Motors for Astronomical Mirrors

2008 IEEE Industry Applications Society Annual Meeting, 2008
Compensating the atmospheric turbulence with adaptive optics techniques dramatically improves ground-based astronomical images. As the image quality of a telescope depends on the level of the rapid turbulence corrections, a very high deformation accuracy of the adaptive optical surface must be achieved.

Research on Linear Motor for Linear Compressor

Advanced Materials Research, 2011
A novel moving-magnet linear motor was introduced which can produce high-frequency short stroke reciprocating motion, and it’s suitable to apply in linear compressor. The equivalent magnetic circuit model was established and the expression of driven force was given, then the impact the motor parameters made to motor performance was analyzed.

A linear piezoelectric motor

Smart Materials and Structures, 1998
The development of a linear hybrid transducer type piezoelectric motor is shown. This design has the advantages of light weight, macro- and micro-positioning, and large force/velocity output. The motor consists of a longitudinal actuator that provides output displacement and force, and two alternating clamping actuators which provide the holding force.
