Claims15
A rotor for a permanent magnet electrical machine, comprising:
- a rotor house having a rotor house yoke, the rotor house yoke comprising for each of a plurality of permanent magnet units, a magnet unit contact face and at least one through hole;
- at least one permanent magnet unit of the plurality of permanent magnet units having a rotor house contact face;
- and
- a fixing material portion between the magnet unit contact face of the rotor house yoke and the rotor house contact face of the at least one permanent magnet unit for fixing the at least one permanent magnet unit to the rotor house.
A method of manufacturing a rotor for a permanent magnet electrical machine, the method comprising:
- machining, at a rotor house yoke of a rotor house, for each of a plurality of permanent magnet units, a magnet unit contact face and at least one through hole;
- arranging a rotor house contact face of at least one permanent magnet unit at the magnet unit contact face;
- injecting fixing material through the through hole, to form a fixing material portion between the magnet unit contact face of the rotor house and the rotor house contact face of the magnet unit for fixing the at least one permanent magnet unit to the rotor house.
