Abstract

A radiation treatment system 100, 300 includes a base stand 200 fixed to or resting on a support surface external to the radiation treatment system, a rotatable gantry 110 with a treatment-delivering radiation source mounted thereon, wherein the rotatable gantry is rotatably coupled to the base stand via a bearing 205, and an electric motor for rotating the rotatable gantry and a portion of the bearing fixed to the gantry. The electric motor includes a first assembly 510 that is fixed to the base stand; and a second assembly 520 that is fixed to the gantry and is separated from the first assembly by an air gap 501, wherein magnetic flux across the air gap causes the electric motor to rotate the rotatable gantry and the portion of the bearing fixed to the rotatable gantry.
