Summary:The invention discloses a magnetic permeance-controllable milled composite spindle permanent magnet synchronous torque motor, which comprises a rotor core, permanent magnets and a triphase winding, wherein the rotor core is arranged on the inner side of a stator core; the permanent magnets are arranged between the rotor core and the stator core in a surface mounting way; and the triphase winding is arranged in a stator slot formed on the rotor core. The motor is characterized in that: a magnetic permeance-controllable coil is arranged on a magnetic-permeable bridge, and then the magnetic-permeable bridge is embedded into the rotor core; or the magnetic-permeable bridge is directly arranged on the stamped steel of the rotor core, and then the magnetic permeance-controllable coil is wound on the magnetic-permeable bridge. The motor has the advantages that: low power is provided for the magnetic permeance-controllable coil, and can relatively more greatly change the magnetic permeance of the magnetic-permeable b
