Document Type and Number:
WIPO Patent Application WO/2022/149947
Kind Code:
A1
Abstract:
The present invention relates to a motor assembly connection ring and a manufacturing method therefor, and a motor assembly. A motor assembly of the present invention comprises: a housing; an impeller provided in the housing; a stator provided in the housing and having a plurality of phase coils; a rotor which has a rotation shaft connected to the impeller and is disposed to be rotatable with respect to the stator; and a connection ring formed of an electric conductor and simultaneously connected to one ends of the plurality of phase coils, wherein the connection ring includes: a ring-shaped body having an open side; and a plurality of phase coil connection units respectively extending in a radial direction from the body and respectively connected to ends of the plurality of phase coils. Accordingly, the production yield (stamping yield) of the connection ring can be increased.
