Abstract
The present invention relates to a BLDC motor integrated with an inverter, having a motor and an inverter part that are integrally formed, and to a BLDC motor integrated with an inverter, having an improved arrangement of switching elements mounted on a PCB substrate of an inverter part and three phase terminals of a stator coil such that the inverter part including the PCB substrate can be compactly formed.
Claims19
An inverter-integrated type brushless direct current (BLDC) motor comprising:
- a motor including three phase terminals electrically connected to a driving coil of a stator and arranged to be spaced apart from each other in a circumferential direction with respect to a central axis of the stator;
- and
- an inverter part coupled to the motor and having a PCB on which switching elements are mounted such that the three phase terminals are coupled to the PCB and are electrically connected to the switching elements,
- wherein the inverter part includes the inverter housing having a shape of a concave container, coupled to the motor on an outer side thereof, and having the PCB provided on an inner side thereof, and the inverter housing includes through holes formed in a penetrating manner between the motor and the PCB, so that the other sides of the three phase terminals, whose one sides are coupled and fixed to the stator, pass through the through holes of the inverter housing so as to be coupled to the PCB.

An inverter integrated BLDC motor comprising:
- a motor;
- an inverter housing coupled to the motor on one side thereof;
- a PCB coupled to the other side of the inverter housing and spaced apart from the inverter housing in other portions excluding the coupled portion, and allowing electronic elements including the switching elements to be mounted thereon;
- and
- a capacitor and an electromagnetic wave shielding filter mounted on the PCB and disposed at an outer region of the PCB so as to be in contact with the thermal grease on the other side of the inverter housing;
- wherein a first heat dissipation fin protrudes from a position corresponding to a portion coupled to the PCB on one side of the inverter housing, and
- wherein protrusions protrude from one side of the inverter housing at positions corresponding to the capacitor and the electromagnetic wave shielding filter.
