Electric motor-driven wheel for wheelchair, has permanent magnets fixed at rim bed region made from ferromagnetic material, and arranged in interior of wheel in relation to electrical coils, where drive is designed as wheel hub drive

摘要

The wheel (1) has a rim bed (4) designed in the form of a ring running in a radial manner, and made from ferromagnetic material e.g. steel or ferrous alloy. A drive is designed as a wheel hub drive. A part of a wheel disk (3) is made from non-ferromagnetic material e.g. aluminum or aluminum alloy. Permanent magnets of electric motor are fixed at a rim bed region made from ferromagnetic material and are arranged in an interior of the wheel in relation to electrical coils. A radially running annular space (7) is present between the bed and a drum brake (8) to receive the magnets and the coils.
