Embodiment Construction
[0024] The specific embodiment described in the present invention is a permanent magnet synchronous motor for use in a wheel, that is, an in-wheel motor. However, the present invention can also be applied to other types of permanent magnet synchronous motors, as is well known to those skilled in the art. This type of electric motor has a set of coils which is part of a stator for mounting to a vehicle, axially surrounded by a rotor with a set of magnets for mounting to a wheel. Furthermore, some aspects of the present invention are applicable to a device having a rotor self-fitted into an axially surrounding coil.
[0025] The physical device of the concrete implementation of the present invention can refer to figure 1 with figure 2 to be best understood. The device may be described as an electric motor with built-in electronics and bearings, or when the device is constructed to accommodate separate wheels, it may also be described as a hub motor or hub drive. However, th...
