Abstract

An embodiment relates to a controller and a motor assembly comprising same, the controller comprising: a substrate; a controller housing disposed on the substrate; a CM filter unit disposed between the substrate and the controller housing; a DM filter unit disposed under the CM filter unit; a controller cover disposed between the substrate and the DM filter unit; a power module unit disposed between the substrate and the controller cover; and a connector unit coupled to the substrate, wherein the power module unit comprises a power module and a mold unit surrounding the power module. Accordingly, the heat generating problem of the power module unit can be resolved.

Description

technical field [0001] Embodiments relate to a controller and a motor component including the same. Background technique [0002] A motor is a device that converts electrical energy into rotational energy using the force applied to a conductor in a magnetic field. Recently, as the use of motors has expanded, the role of motors has become important. In particular, with the rapid development of electrification of vehicles, the demand for motors used in steering systems, braking systems, interior systems, etc. has greatly increased. [0003] In the case of such a motor for a vehicle, a motor part including a controller capable of controlling the motor may be provided in the vehicle. [0004] Due to the high current used in the controller, there was a heating issue. For example, in the case of using a substrate in a controller, a direct current (DC) power circuit, a control circuit, and an inverter circuit are provided on the substrate. In addition, when a large current is a...
