A multiphase linear motor has an elongated stator with a stack of permanent magnets end-to-end along its length and a coaxial drive coil configuration which is such as to leave a gap permitting mechanical support of the permanent magnets at least at intervals along the length of the stator intermediate its ends. Specifically the drive coils comprise sub-coils with arcuate turns which subtend less than 360° around the motor axis to leave free a gap for the aforementioned mechanical support.
