Abstract
A magnetic pump 1 includes an impeller 7, a shaft 8, an annular magnet 6, a housing 5 and a core 2. The impeller 7 is mounted in the annular magnet 6 and on the shaft 8, such that it can rotate in the housing 5. The housing 5 is mounted in arms 4A, 4B of the core 2, such that when windings (not shown) energise the core 2, the annular magnet 6 and the impeller 7 are caused to rotate. The windings may be supported between flanges 3A, 3B on the core 2, and the shaft 8 may be supported in the housing 5 by a bar 9. An inlet and outlet 5A, 5B of the housing 5 may be connected to water flow pipes, and the pump 1 may be operated from an AC or DC electricity supply.
Description
Title: Prime Mover
The present invention relates to a prime mover, and particularly to a pump.
Water pumps, such as used in washing machines, are well known in which an impeller is rotated in a housing. The electric motor is mounted externally to the housing and drives the impeller through a shaft passing through a waterproof seal in the housing wall. A problem with such pumps is that the connection between the motor and impeller is inefficient and the seal can leak, and the water flow through the housing is not in a straight line.
The invention seeks to provide an improved prime mover, such as a water pump.
According to the present invention there is provided a prime mover comprising a substantially
U-shaped core with windings to energise the core, the arms of said U-shaped core embracing a generally cylindrical housing, and a magnet in the shaped of an annulus mounted for rotation in said housing between the arms of the core, said magnet rotating upon said core being energised.
Preferably the prime mover is a pump and an impeller is mounted in said annulus. Preferably the impeller is mounted to rotate on a shaft axially aligned in the housing, said shaft being connected to the housing.
Preferably the ends of the cylindrical housing form an inlet and outlet each connectable to a pipe whereby the impeller is in line with the flow of fluid through the pump.
The pump may be a water pump.
An embodiment of the invention will now be described with reference to the accompanying drawings in which:
Figure 1 shows a perspective view of the prime mover assembled, and
Figure 2 shows a perspective view of the impeller and magnetic annulus removed from the prime mover of Figure 1.
Referring to Figure 1 there is shown a prime mover in the form of a water pump 1.
Pump 1 has a substantially U-shaped core 2 formed from a series of laminations 2A of iron as is known in the art. The top end of each arm of core 2 is adapted to receive one or more wire windings (not shown but known in the art) supported between winding support flanges 3A, 3B.
The Windings are connectable to a source of electricity to energise the core.
The lower ends 4A, 4B of each arm of core 2 are C-shaped to embrace a generally cylindrical housing 5 which may be formed from any suitable material such as tubular plastics. The ends of housing 5 effectively form a pump water inlet SA and water outlet 5B and may each be connected (not shown) to a water flow pipe.
As shown more clearly in Figure 2, a magnetic annulus 6 is provided having a outer diameter just less than the internal diameter of the housing 5. Mounted inside the annulus 6 is an impeller 7 with the tips of the impeller blades connected to the annulus 6. The rotational axis of the impeller and the annulus is supported by a shaft 8. Shaft 8 is connected to a bar 9, the ends 9A, 9B of which each rest in a recess 5C, 5D on the inside of the housing 5 wall. The shaft 8 is thus also axially aligned with the housing 5.
Annulus 6 and impeller 7 can rotate on shaft 8 within the housing. When the core 2 is energised, the annulus will rotate and thus rotate the impeller.
In use water can be driven through the housing 5. With the inlet and outlet 5A, 5B of the housing connected to water flow pipes, the impeller 7 is in line with the flow of water through the pump.
The prime mover can be designed to operate from an AC or DC supply of electricity.
The water pump described has few working parts and few joints. It is lightweight, and has no seals to leak.
The prime mover of the invention could be other than a water pump and could be used to pump fluids other than water. It could also be other than a pump, e. g. the annulus could be used to rotate another member other than impeller.
Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.
Claims (3)
- CLAIMS 1. Prime mover pump assembly, the assembly comprising an impeller is mounted in magnet annulus so arranged to rotate on shaft fixed axially aligned in the housing, a part of the housing between the arms of the core which provide with windings to energise the core.
- 2. The housing as claimed in claim 1 provided with inlet and outlet.
- 3. A method of pump fluid of prime mover comprising substantially in shaped core with windings when supplied with electricity to energise the core, the arms of said core embracing a part of the housing, and magnet in the shaped of an a annulus mounted rotate with impeller pushing the fluid through the out let of housing causing the fluid to inter through the inlet.
