Claim 10:
11. A method comprising:
receiving operational parameters corresponding to a desired operational state of a cryocooler controlled by a cryocooler controller;
generating control signals based, at least in part, on the received operational parameters; and
generating, by a motor driver of the cryocooler controller, coil signals based, at least in part, on the control signals, to cause a motor coil of the cryocooler to generate the varying magnetic field, wherein:
the cryocooler comprises:
a displacer; and
a magnetic system comprising the motor coil and a magnet configured to couple magnetically with a varying magnetic field generated by the motor coil to control a motion of the displacer;

wherein in response to the varying magnetic field generated by the motor coil, both the motor coil and the magnet reciprocate to move in opposite directions from each other.
