Abstract
A 7-phase multistage linear induced electromagnetic propeller comprises a driving coil, an armature, pulse power supplies and a charger. The driving coil is formed by a plurality of double-pancakes which are coaxially arranged on an insulation skeleton and is divided into multiple stages. Each stage of the driving coil is externally connected to one group of the pulse power supplies. A single-phase power supply in one group of the pulse power supplies is formed by one pulse capacitor and one discharging switch. One charger charges the capacitors of all the pulse power supplies. The multistage driving coils are coaxially arranged on one insulating sleeve and are fixed. The armature is placed in a first stage driving coil. The armature forges ahead linearly in the driving coil under an electromagnetic force effect. The armature accelerates from the first stage driving coil. When the armature arrives at a position of a next stage driving coil, the pulse power supplies which are externally connected to the stage driving coil begin to discharge. And the armature continuously forges ahead.
