The invention relates to a linear motor type damper in a drive wheel and belongs to the technical field of auto parts. The linear motor type damper mainly comprises motor dampers, wheels, a passive suspension spring and a passive damper, wherein each motor damper is mounted in the corresponding wheel through a support and comprises a peripheral magnetism isolating sleeve, an end cover, a rotor, a stator, a self-lubricating positioning bearing and the support; the rotor comprises an annular rotor iron core, a winding coil and a Hall sensor, and the inner ring of the rotor iron core is provided with annular grooves and rotor teeth; the stator comprises an annular in-diameter-magnetizing permanent magnet, an annular right-side-magnetizing performant magnet, an annular out-diameter-magnetizing permanent magnet, an annular left-side-magnetizing permanent magnet, annular stator magnetic back iron and a columnar support shaft; the motor damper is in parallel connection with the passive suspension spring and the passive damper which are mounted outside the wheels. The linear motor type damper is adjustable in operating force, passive in energy recycling, small in size, large in travel, and the like.
