Patent ID: 8847453

Claim:
A method for manufacturing a rotor for an electric machine, comprising: bonding permanent magnets to one another by a first adhesive to form a magnetic element, wherein each permanent magnet has a side with a magnetic North pole and a side with a magnetic South pole, wherein the permanent magnets are arranged during bonding such that the sides of the magnetic North poles or the sides of the magnetic South poles from a common underside of the magnetic element, and wherein the first adhesive has a hard consistency in a cured state to prevent the permanent magnets from moving away from one another, and bonding the underside of the magnetic element to a soft and elastic layer of the yoke by a second adhesive, wherein the second adhesive in a cured state is soft and elastic to resist a rupturing caused by a difference between an expansion of the yoke and an expansion of the magnetic element when being exposed to an increased temperature.
