Shaft motors have been widely used in motion control systems and machine
tools due to their capability for high-speed performance, high acceleration
and deceleration as well as accurate positioning. The magnet is arranged
in the center of the coil and the magnetic flux that is produced can be
efficiently converted into thrust force. This example presents the use
of a magnetic field analysis to obtain the thrust force of a shaft motor.

104 - Thrust Force Analysis of a Linear Induction Motor

Module:TR |

A linear induction motor can be constructed at low cost, because the motor
can use a primary side made of coil, and secondary side made of a conductor
that is not magnetized, such as aluminum or copper. It is important to
analyze the thrust force as well as the end effect that causes lower performance
at low slip when evaluating the performance of linear induction motors.This
example analyzes the thrust force of a linear induction motor.

65 - Analysis of Static Thrust of a Voice Coil Motor

Module:TR |
2011-01-17 |
Coreless linear actuators are used for the head drive of electronic packaging
machines and precision stages, both of which require high accuracy positioning.
Static thrust has a great effect on accurate positioning, since it varies
with the translation position of an actuator. Also, static thrust varies
with the amount of current, so it is important to obtain the static thrust
at each supply current from the analysis. This note presents the use of
magnetic field analysis to obtain static thrust characteristics of a voice
coil motor at different translation positions and different supply currents.

64 - Thrust Force Analysis of a Coreless Linear Motor

Module:TR |

Coreless linear motors are used for linear motor stages and electronic
packaging machines. Generally, the thrust force of a coreless linear motor
is smaller than that of an iron core linear motor. Since a coreless linear
motor has no cogging, its thrust force variation is much less than an iron
core linear motor. This note presents the use of magnetic field analysis
to obtain the thrust force of a coreless linear motor.
