Definitions
- the present invention relates generally to electric motors, and, more particularly, to water-resistant electric motors.
- Figs. 1 and 2 illustrate a combined ice shaver and blender of the prior art.
- the blender functionality may be provided by a blender cup having an impeller at the bottom of the cup.
- the impeller may be coupled to a ferrous drive plate rotatably mounted in a base of the blender cup such that the impeller rotates with the drive plate.
- the blender cup is removably received on top of a magnetic drive of the appliance configured to magnetically drive rotation of the drive plate in the blender cup, thereby causing rotation of the impeller.
- the magnetic drive may include a brushless d.c.
- the motor having stator windings and a rotor assembly, wherein the rotor assembly includes a ring-shaped drive magnet carried in a hub and configured to magnetically drive rotation of the drive plate in the base of the blender cup.
- the drive ring magnet is about five inches in diameter and weighs approximately three pounds. With typical operating speeds varying from 4,000 to
- the rotating drive ring magnet can exert significant forces on the mounting structures, particularly rapidly varying forces that produce noise and vibrations.
- Heat and pressure buildup within a housing of the drive motor are concerns during motor operation.
- the stator windings and sensing electronics for providing motor control feedback must be protected from exposure to liquid, so an open- vented housing is not an available solution for relieving heat and pressure buildup.
- the invention provides a magnetic drive assembly characterized by a housing configured to dissipate heat and pressure.
- the magnetic drive assembly comprises a housing including a cylindrical end bell portion and a cylindrical hub portion at an open end of the end bell portion, wherein the radius of the hub portion is greater than the radius of the end bell portion.
- One or more mounting tabs extend radially outward from the hub portion, wherein each tab includes a fastener hole.
- the housing further comprises at least one heat transfer fin contacting the hub portion and the mounting tab.
- a stator assembly and a rotor assembly are contained in the housing, with the stator assembly being received in the end bell portion.
- the rotor assembly includes a hub having a ring-shaped recess located in the hub portion of the housing, and a drive ring magnet is carried in the recess of the hub.
- each tab has a plurality of first heat transfer fins having an axially extending edge contacting the hub portion and a plurality of second heat transfer fins having an axially extending edge contacting the end bell portion.
- Each of the first heat transfer fins may have a radially extending edge contacting the mounting tab
- each of the second heat transfer fins may have a radially extending edge contacting the hub portion and the mounting tab.
- Each first heat transfer fin may form a gusset support between the hub portion and the mounting tab
- each second heat transfer fin may form a gusset support between the end bell portion and the mounting tab.
- the first heat transfer fins may be arranged on an opposite side of the mounting tab relative to the second heat transfer fins, whereby the mounting tab is braced in opposite axial directions.
- the housing may further comprise at least one pressure equalization vent allowing passage of gas but not passage of liquid into and out of the housing.
- FIG. 1 is a perspective view of a combination ice shaver and blender according to known prior art
- FIG. 2 is a schematic cross-sectional view of the combination ice shaver and blender shown in Fig. 1;
- FIG. 3 is a sectioned perspective view of a blender cup magnetic drive formed in accordance with an embodiment of the present invention
- Fig. 4 is a top plan view of the magnetic drive shown in Fig. 3;
- FIG. 5 is a side elevational view of the magnetic drive shown in Fig. 3;
- Fig. 6 is a bottom plan view of the magnetic drive shown in Fig. 3;
- Fig. 7 is a perspective view of the magnetic drive shown in Fig. 3;
- FIG. 8 is another perspective view of the magnetic drive shown in Fig. 3.
- Fig. 9 is a further perspective view of the magnetic drive shown in Fig. 3.
- FIGs. 3-9 illustrate a magnetic drive assembly 10 formed in accordance with an embodiment of the present invention.
- Magnetic drive assembly 10 may be used to magnetically drive rotation of an impeller located in a blender cup positioned on top of the magnetic drive assembly in a blender device.
- magnetic drive assembly 10 generally comprises a housing 12, a stator assembly 14, a rotor assembly 16 including a hub 18, and a drive ring magnet 22 carried in a ring-shaped recess 20 of the hub.
- An electrical lead bundle 13 enters housing 12 through a sealing grommet 15.
- Housing 12 includes a cylindrical end bell portion 24 having a first radius
- Housing 12 further includes a plurality of mounting tabs 28 extending radially outward from hub portion 26, and at least one heat transfer fin 30, 31 contacting hub portion 26 and a mounting tab 28.
- Each mounting tab 28 may include one or more fastener holes 32.
- housing 12 has six mounting tabs 28, however more or fewer mounting tabs may be provided.
- a single mounting tab 28 may be provided in the form of a continuous annular flange encircling hub portion 26.
- second radius R2 may be greater than first radius Rl, resulting in a radial step where end bell portion 24 meets hub portion 26.
- Stator assembly 14 is received in end bell portion 24, and includes a plurality of windings 34 angularly spaced about a rotational axis of rotor assembly 16.
- the end bell portion 24 of housing 12 defines an axially-extending internal sleeve 36 in which a drive shaft 38 of rotor assembly 16 is rotatably mounted by a pair of rotary bearings 40.
- Hub 18 is fixedly mounted on drive shaft 38, and includes a stem portion
- a rotor ring magnet 44 is fixedly arranged about hub stem portion 42 radially opposite stator windings 34.
- stator windings 34 when stator windings 34 are energized and commutated, rotor assembly 16 including hub 18 will rotate relative to stator assembly 14 and housing 12.
- drive ring magnet 22 carried in ring-shaped recess 20 of hub 18 will also rotate to magnetically drive the blender cup impeller.
- housing 12 includes a plurality of first heat transfer fins 30 each having an axially extending edge 30A contacting hub portion 26 of housing
- first heat transfer fins 30 each have a radially extending edge 30B contacting the associated mounting tab 28.
- the second heat transfer fins 31 each have a radially extending edge 3 IB contacting hub portion 26 and the associated mounting tab 28.
- First heat transfer fins 30 may be arranged on an opposite side of mounting tab 28 relative to second heat transfer fins
- first heat transfer fins 30 may form a gusset support between hub portion 26 and associated mounting tab 28, and the second heat transfer fins 31 may form an opposing gusset support between end bell portion 24 and associated mounting tab 28.
- mounting tabs 28 are supported in opposite axial directions.
- Housing 12 may be formed from a strong material having relatively high thermal conductivity. Aluminum is considered a suitable material for housing 12, however other materials may be used.
- housing 12 may further comprise one or more pressure equalization vents 46 allowing passage of gas but not passage of liquid into and out of housing 12.
- pressure equalization vents 46 are suitable for use as pressure equalization vents 46.
