A reversible linear motor has a coil arrangement arranged alongside a conductive body such as a rotatable aluminium disc. The coil arrangement is made up of three separate coils: namely an inner coil and two interconnected outer coils on opposite sides of the inner coil. The coils are connected to a single phase a.c. supply and the drive of the disc can be reversed by reversing the connection of the inner coil relative to the two outer coils. The linear motor may be used for driving a reel of an entertainment machine of the fruit machine kind. |
