CubeMars AK80-6 High torque 12Nm gear motor linear actuator motor for legged robot

We get inspiration from the robot dog motor , Always ,we want to develop a small motor with gears.It needs to be different from our regular products .The gears doesn't need to be attached the motor ourside ,So we find that the space in motor stator might be a good choice to set up the gears ,we try that and it worked !

Also,more surprised the whole acuator only 400g of weight !
