Definitions
- This invention relates generally to electric motors and more particularly, to an endshield assembly for an electric motor.
- Known electronically commutated motors have a multi-stage winding assembly and a magnetic assembly associated for relative rotation.
- the winding stages of the multi-stage winding assembly have a preset energization sequence that includes at least one unenergized winding stage in which an induced back EMF appears.
- the induced back EMF indicates the instant at which the relative angular position between the multistage winding assembly and the magnetic assembly is suitable for the sequential commutation of the next winding stage.
- the electronic circuitry for an electronically commutated motor generally includes a power circuit, a regulating circuit, and a control circuit.
- the power circuit has solid state switching devices for commutating the power supplied to the electronically commutated motor to effect its energization.
- the regulating circuit has various solid state components for maintaining the power supplied to the electronically commutated motor generally constant.
- the control circuit has various solid state components for controlling the conductivity of the switching devices.
- an electronically commutated motor e.g. , transistors
- solid state components for an electronically commutated motor e.g. , transistors
- Large transistors can produce a sizable amount of heat that should be dissipated from the transistors in order to keep them functioning properly.
- the electronic circuitry for an electronically commutated motor can be positioned adjacent an outer surface of an endshield of the motor. However, this increases costs since another compartment is needed to protect the electronic circuitry.
- a motor endshield assembly for an electronically commutated motor includes an endshield having an inner surface and an outer surface, with the outer surface including a plurality of recessed fins.
- the endshield assembly according to one embodiment of the present invention includes a control assembly and a power assembly mounted thereto.
- the control assembly includes a control board having a plurality of power transistors.
- the internal surface of the endshield includes a substantially flat raised area that is in contact with the control assembly and serves as a heatsink for the power transistors.
- the transistors are in contact with a thermal pad located between the transistors and the endshield.
- the thermal pad electrically insulates the transistors yet still conducts heat from the transistors to the endshield.
- the recessed fins are located directly above the substantially flat raised portion on the endshield and assist the dissipation of heat from the transistors and endshield to the ambient environment.
- the power assembly includes a power board having an insulator positioned between the power board and the control board.
- a first spacer extends between the control board and the power board to provide the proper spacing therebetween.
- a plurality of clamp bars are also positioned between the power board and the transistors. The clamp bars apply pressure to the transistors and keep the transistors in contact with the substantially flat raised portion of the endshield.
- the first spacer and the clamp bars extend through the insulator.
- a second spacer extends between the control board and the endshield to provide the proper spacing therebetween.
- each power transistor includes a plurality of leads that extend substantially parallel to the control board.
- the leads exit a front side of the transistor at a position that is closer to a bottom of the transistor than to a top.
- the bottom of the transistor is in contact with the control board while the top of the transistor includes a tab that extends from a back side of the transistor parallel to the control board.
- the endshield assembly only one compartment is required since the electronic controls are located within the motor housing.
- use of the endshield as a low impedance path to dissipate heat from the power devices of the internal electronic circuitry to the ambient environment provides good thermal performance for the motor.
- the transistor leads are parallel to and away from the control board, the lengths of the leads are much closer to the surface of the board than in many known control assemblies. The leads are thus easy to encapsulate and protect from harsh external environments.
- Figure 1 is an exploded view of an endshield assembly in accordance with one embodiment of the present invention
- Figure 2 is a perspective view of the endshield shown in Figure 1 ;
- Figure 3 is a cross section of the endshield shown in Figure 2 along A-A;
- Figure 4 is a schematic illustration of the thermal pad shown in Figure 1 ;
- Figure 5 is a schematic illustration of the insulator shown in Figure 1.
- FIG. 1 is an exploded view of an endshield assembly 100 for an electronically commutated motor (not shown).
- Endshield assembly 100 includes an endshield 102, a control assembly 104, and a power assembly 106.
- Control assembly 102 includes a control board 108, a plurality of transistors 110, a thermal pad 112, and a spacer 114.
- spacer 114 is fabricated from nylon and extends between control board 108 and endshield 102. Spacer 114 helps to maintain a predetermined separation distance between control board 108 and endshield 102.
- Transistors 110 include a front 116, back 118, top 120, bottom 122, and a tab 124.
- Tab 124 extends from back 118 of transistors 110 and has a surface 126 that is an extension of, and is substantially parallel to, top 120.
- a plurality of leads 128 extend from front 116 of transistor 110.
- leads 128 extend substantially parallel to control board 108 and maintain a substantially constant separation distance between themselves and control board 108. Since leads 128 extend from front 116 in a location that is closer to control board 108 than to top 120, leads 128 remain relatively close to control board 108 throughout their length. Only a small separation distance exists between leads 128 and control board 108.
- leads 128 To insert leads 128 into control board 108, leads 128 must be formed at right angles to transistor 110.
- Transistors 110 are capable of producing significant heat depending on the amount of current that flows through them. The heat should be dissipated from the transistors and the surrounding motor in order to ensure proper operation of the motor.
- top 120 of each transistor 110 is in thermal contact with thermal pad 112. Thermal pad 112 electrically isolates transistors 110 and conducts the heat generated by transistors 110 away from transistors 110.
- Thermal pad 112 contacts endshield 102 which includes an inner surface (not shown) and an outer surface 130 that has a plurality of recessed fins 132.
- endshield 102 is fabricated from cast aluminum and serves a heatsink for transistors 110.
- the inner surface of endshield 102 includes a substantially flat raised portion (not shown).
- the substantially flat raised portion is in thermal contact with thermal pad 112 and is located directly beneath recessed fins 132.
- recessed fins 132 extend from the substantially flat raised portion.
- the heat from transistors 110 travels through thermal pad 112 to endshield 102 and is dissipated from recessed fins 132 to the ambient environment.
- Endshield 102 serves as a heat sink to transistors 110 and helps to dissipate heat from transistors 110 to the ambient environment. This heat dissipation helps reduce stress on transistors 110. Endshield 102 further includes a cap plug opening 134 and a cap plug 136 as will be discussed in more detail below.
- Power assembly 106 includes a power board 138, electronic components
- Insulator 146 is positioned between control board 108 and power board 138 and electrically insulates portions of control board 108 from portions of power board 138.
- Spacer 142 and clamp bars 144 extend between control board 108 and power board 138. Spacer 142 and clamp bars 144 facilitate maintaining a predetermined distance between power board 142 and control board 108. Spacer 142 and clamp bars 144 extend through insulator 146 and are in contact with both control board 108 and power board 138.
- spacer 142 is fabricated from nylon.
- Clamp bars 144 are positioned on an opposite side of power board 138 from electronic components 140 and are located between electronic components 140 and transistors 110. Clamp bars 144 apply pressure on transistors 110 to ensure a good thermal interface between transistors 110 and endshield 102.
- FIG. 2 is a perspective view of endshield 102.
- Endshield 102 includes a shaft opening 148 for a rotor bearing (not shown).
- outer surface 130 of endshield 102 includes a raised cylinder 150 that projects from endshield 102 and surrounds opening 148.
- Raised cylinder 150 includes a resilient ring (not shown) mounted therein.
- Endshield 102 further includes a plurality of bolt openings 152. Bolt openings 152 extend through endshield 102 and through bolts
- Cap plug opening 134 extends through endshield 102 and allows access to internal components (not shown) during final testing and calibration. Cap plug opening 134 permits access to the internal components without having to remove endshield 102.
- Cap plug 136
- cap plug opening 134 (not shown in Figure 2) covers cap plug opening 134 to protect the internal components.
- Figure 3 is a cross-section view of endshield 102 and illustrates an inner surface 154 that includes a substantially flat raised portion 156.
- Raised portion 156 is located directly beneath recessed fins 132 and is a component of a thermal pathway between transistors 110 (not shown in Figure 3) and recessed fins 132.
- Recessed fins 132 extend from raised portion 154 to increase the surface area of outer surface 130 which facilitates the dissipation of heat from endshield 102.
- Raised cylinder 150 and bolt opening 152 are also illustrated in Figure 3.
- FIG 4 is a schematic illustration of thermal pad 112.
- thermal pad 112 includes angled sides to permit increased contact with a portion of endshield 102 (not shown in Figure 4).
- Thermal pad 112 has two openings 158 to help secure thermal pad 112 to the endshield.
- FIG 5 is a schematic illustration of insulator 146.
- Insulator 146 includes two openings 160 through which clamp bars 144 (not shown in Figure 5) extend. Openings 160 are generally rectangular in shape and are positioned in close proximity to each other. Insulator 146 also includes a shaft opening 162 through which a shaft (not shown) of the electronically commutated motor extends. Insulator 146 is fabricated from mylar and provides both thermal and electrical insulation. Insulator 146 also includes a spacer opening 164 through which spacer 142 (not shown in Figure 5) extends.
- Endshield assembly 100 includes a thermal pathway that allows heat to be dissipated from the interior of endshield assembly 100, to the ambient environment.
- This thermal pathway enables control assembly 104 and power assembly 106 to be placed within the interior of the electronically commutated motor housing.
- This interior placement eliminates the need for a separate compartment to house the electronic controls of the motor, and facilitates reducing fabrication costs of the motor.
- the orientation of the transistor leads enables the leads to be encapsulated and protected from potentially harsh environmental conditions.
