Power Tool Commutator Solution
2022-10-20
Kommutatorn används ofta inom bilindustrin, hushållsmotorer och elektriska verktyg. Den grundläggande strukturen för kommutatorn är: inklusive kommutatorkopparplåtarna jämnt fördelade på den yttre omkretsen av kommutatorkroppen och kommutatorkroppen. Sammanbildat är det kommuterande koppararket försett med ett stycke fot som implanteras i kommutatorkroppen och fast kombineras med kommutatorkroppen.
In order to strengthen the bonding strength between the commutator copper sheet and the commutator body, and improve the mechanical properties of the power tool commutator products, the most commonly used method is to improve the structure of the chip feet and set the reinforcement ring, and the improvement of the chip foot structure is the most ideal. The technical solution is to increase the size of the film feet. However, for power tool commutator products with small radial size and large number of commutation copper sheets, the size of its feet is strictly limited in both the circumferential and radial directions, and each adjacent commutation is strictly limited. The distance between the inner sides of the pins of the copper sheets will be very small. If the radial dimension of the pins is increased, the adjacent pins will easily touch when the commutating copper sheets and the commutator body are injected together. , resulting in a high rejection rate of commutator products after injection molding.

Med tanke på bristerna i den befintliga tekniken tillhandahåller vi en ny kommutatorteknisk lösning, som kan förbättra fastheten i kombinationen mellan kommutatorkopparplåten och kommutatorkroppen, vilket gör en elverktygskommutator med högre produktkvalitet.
