Summary:An ultralow-speed unitary spliced-disc maglev torque motor comprises a base and a pair of unitary spliced-disc direct-drive motors and is characterized in that a center rotator in rotational symmetryand a pair of conical active biased maglev bearings that restrain axial and radial motion of the center rotator are provided, and maglev supporting is provided for a rotary shaft; a pair of radial protection bearings, a pair of axial protection bearings and a position feedback system are also provided correspondingly; on this basis, the unitary spliced-disc direct-drive motors drive the center rotator in redundant or synchronous manner. The direct-drive motor, the maglev bearings, the axial and radial protection bearings and a feedback and braking system are integrated, the structure is simpleand compact, the integrity is high, space utilization is increased, machining cost and power electronic component cost can be effectively reduced, and product competitiveness is greatly improved. 超低速单元式拼接盘式磁悬浮力矩电机，包括有基座、对单元式拼
