Innovation Highlights Rotors of high frequency or high torque motors often have a magnet wrap that is not strong enough to achieve the required speed, and if the wrap preload is too high, cracks in the magnet body, failure of the associated mating parts, and fragmentation or dislodgement of the magnets can lead to premature failure of the motor. We can provide effective reinforcement of the rotor magnets using carbon fiber CFRP sheaths. For non-precision high speed applications, at low loads (torque) and low speeds, the use of fiberglass wound, or carbon fiber reinforced magnets will protect the magnet body even when not pressurized. However, if the load is too high or the rotational speed is too high, normal winding strength will not be able to counteract the torque or the centrifugal force generated by the rotation. In this case, the CFRP rotor must be pre-pressurized on the magnet surface using high pressure on the magnet. As a result, higher speeds can be achieved before the magnet reaches its allowable tensile stress.
