Multi-Dimensional Layered Pulse Motor

Abstract

A pulse hub motor having coils (101) and magnets (107) interacting three dimensionally in x, y, and z axes to facilitate both increased power and efficiency through the ability to have more coils (101) in the motor, have each coil (101) perform both push and pull functions, and yet have the flexibility to only use the amount of coils (101) needed for real-time power requirements, whilst regenerating power in both normal drive and braking modes.

Description

[0014] As a feature of this design is customisation, the number of circuits and therefore phases can be increased or decreased by adding or removing columns in the x axis. For demonstration purposes, the invention will now be described by way of a 4 phase example and with reference to the accompanying drawings in which:

[0015] FIGS. 1a and 1b show a face-on cross section of a sample coil, magnet, and pulse configuration shown through the x axis horizontally and the z axis vertically, and describe the interactions in power and motion through phases 1 and 3,

[0016] FIG. 2 shows an inside, face-on view of the stator,

[0017] FIG. 3 shows an inside, face-on view of the rotor, being a car wheel with tyre,

[0018] FIG. 4 shows a side view of the stator with coils arranged offset on the x and continuous on the y axes,

[0019] FIG. 5 shows a cross section of shaft, rotor, and stator separated,

[0020] FIG. 6 shows the items in FIG. 4 connected,

[0038] In FIG. 1a, a phase 1 pulse is fired through coils A, B, C, G, H and I. Coil A pushes Magnet 1 and at the same time pulls Magnet 2. Coil B pushes Magnet 2 and pulls Magnet 3. Coil C pushes Magnet 3. The same principle applies with Coils G, H and I, on Magnets 4, 5 and 6.

[0039] If practical, more layers and magnets can be added.

[0040] FIG. 1b shows the phase 3 pulse (phases 2 and 4 are identical, yet happen on a different x axis column and therefore are not shown in this example), where the magnets have now shifted to the next coils. In FIG. 1b, Coils D, E, F, J, K and L are fired. Coil D pushes Magnet 1 and at the same time pulls Magnet 2. Coil E pushes Magnet 2 and pulls Magnet 3. Coil F pushes Magnet 3. The same principle applies with Coils J, K and L, on Magnets 4, 5 and 6.

[0041] This process is replicated in each of the columns of the x axis. As coil columns in the x axis are purposefully offset with their neighbours (FIG. 4) this ensures that there is always a pulse in operation, the result of which is that the progression of the pulses and therefore the thrust is constant and smooth.

[0042] Coils can recycle energy from the movement of the rotor in both normal drive mode and braking mode by skipping phases if they are not required at that time.

[0043] The pulse hub motor mechanism is made possible by taking the stator (100 in FIGS. 2, 4 and 5), placing a shaft (105) through a bearing (106) in the centre, and attaching the rotor (200 in FIGS. 3 and 5) to the fixing plate (110).

[0044] The completed assembly produces the wheel in FIG. 6.
