摘要： A rotor for use with a hysteresis motor in combination with a centrifuge rotor having a hub. The motor has a stator with an axial length and the motor rotor has a region coextensive with the stator. The motor rotor includes a hollow cylindrical body made of a magnetizable material, having one end firmly connected to the hub, and having a wall with a first thickness in the region that is coextensive with the stator and a second thickness, smaller than the first thickness, which is outside of the region that is coextensive with the stator and which is in the region of the connection of the cylindrical body with the hub. The point of transition from the first thickness to the second thickness of the wall is a predetermined distance from the nearest point of contact of the hub with the cylindrical body so as to increase the magnetic resistance between the hub and the cylindrical body.
