A motor system includes a motor including two Hall sensors configured to output binary values, and a controller configured to control the motor. Both groups share the same control node for their respective final amplifier stages, and both groups share the same amplifier output node. Preferably, each leg is telescopic and is lockable and the central connecting member preferably comprises a releasable locking mechanism. The cooling unit controls the temperature and flow rate of the coolant so as to minimize temperature changes of a movable element and stage, and supplies the coolant to the stationary element. The invention also relates to a device for obtaining such coatings. The receiver digital circuitry includes a digital down-converter circuitry that mixes the digital signal with an intermediate frequency local oscillator signal to generate a digital down-converted signal.
