Original Kurzfassung:
In linear motors, there are three causes of thrust
force fluctuations that affect smooth operation. These are (i) the
cogging forces (ii) the load dependent force fluctuations and (ii)
the end forces resulting from the limited length of the motor.
To the various methods that exist to solve this problem, this
paper adds an unconventional method that takes advantage of
the limited length of the motor. This paper presents a method
to minimize cogging force by changing the slot pitch while pole
pitch and winding layout remain unchanged. One of the main
advantages of this method is that it is easy to apply in motor
design and requires hardly any space.
