Abstract
An integrated coil assembly ( ), a multi-phase linear motor having the integrated coil assembly ( ) and a method ( ) for forming the integrated coil assembly ( ) are described. The integrated coil assembly ( ) has multi-phase coils with each multi-phase coil ( ) having a number of coil loops based upon the number of electrical phases of current required by the multi-phase linear motor. The coil loops of different multi-phase coils are interweaved at two opposing portions ( ) and are substantially parallel at two other opposing portions ( ). In the method ( ), different wire dispensers wind coil loops for different electrical phase for each multi-phase coil ( ). However, the same wire dispenser winds coil loops that are for the same electrical phase for different multi-phase coils ( ). The coil loops for each multi-phase coil ( ) are wound before the coil loops of another multi-phase coil ( ) are wound.
