This invention belongs to the field of motor technology and discloses a high-linearity finite-angle torque motor, comprising a cylindrical rotor and a cylindrical stator, with the rotor housed within the stator. The stator includes N coils and N constant magnetic circuit channels, where N is an even number of at least 2. The rotor's magnet portion has N polarities. The N coils of the stator are evenly arranged circumferentially on the inner side of the stator, with adjacent coils separated by constant magnetic circuit channels. The ends of all coil frames and the ends of the constant magnetic circuit channels together form the rotor's rotational track. Adjacent stator coils have opposite polarities after being energized, and adjacent rotor magnets also have opposite polarities. This invention employs a special stator lamination structure, theoretically eliminating stator cogging torque within the motor's operating angle range, thus improving the linearity of the motor's output torque. Compared to traditional slotted finite-angle torque motors, the output torque fluctuation is reduced by more than 70%.
