Abstract
A pulling head for a crystal growth furnace. The pulling head includes a servomotor and a rotatable housing attached to the servomotor, wherein the housing includes first, second, third and fourth housing magnets. The pulling head also includes a shaft attached to a scale and a connection device having first and second connection magnets. The first connection magnet is arranged between the first and second housing magnets to generate first and second magnetic repulsion forces and the second connection magnet is arranged between the third and fourth housing magnets to generate third and fourth magnetic repulsion forces. A rotation coupling is attached between the shaft and the connection device wherein the scale weighs the shaft, rotation coupling and the connection device. The servomotor rotates the housing and rotation of the housing is transmitted by the magnetic repulsion forces to the connection device to rotate the connection device.
