Example Embodiment

[0023] figure 1 with figure 2 A motor assembly including a motor with a cooling device according to the present invention is shown, wherein the motor assembly includes built-in electronics and is configured to serve as a hub motor or an in-wheel motor housed in a wheel. However, the present invention can be included in any form of electric motor. The electric motor can also be configured as a generator.

[0024] For the purpose of this embodiment, such as figure 1 with figure 2 As shown, the in-wheel motor includes a stator assembly 252 and a rotor assembly 240. The stator assembly 252 includes a heat sink 253 with a cooling channel, a plurality of coils 254, an electronic module 255 installed at the rear of the stator for driving the coils, and a stator installed in a recess 257 formed on the rear of the stator. On the capacitor (not shown). In a preferred embodiment, the capacitor is a toroidal capacitor element.

[0025] The coil 254 is formed on the stator tooth laminate t...

Abstract

An electric motor or generator comprising a stator having stator teeth for mounting electrical coils, a rotor, a first electrical device arranged to control current in the electric coils to generate a rotational torque on the rotor and a second electrical device arranged to modify current provided to the first electrical device, wherein the stator includes a cooling arrangement having a cooling channel arranged to cool the electrical coils, the first electrical device and the second electrical device.

Description

technical field [0001] The invention relates to electric motors or generators, in particular to motors or generators with cooling channels. Background technique [0002] With the growing interest in environmentally friendly vehicles, there has been a corresponding increase in interest in the use of electric motors for providing drive torque for electric vehicles. [0003] Electric motors work on the principle that a current carrying wire experiences a force in the presence of a magnetic field. When a current-carrying wire is placed perpendicular to a magnetic field, the force experienced by the current-carrying wire is proportional to the flux density of the magnetic field. Typically, in an electric motor, the force experienced by the current-carrying wire is developed as a rotational torque. [0004] Examples of known types of motors include induction motors, brushless permanent magnet motors, switched reluctance motors and synchronous slip ring motors, which include a ro...
