Abstract
A drive system includes an electric motor having a rotor and a stator. A nut is rigidly connected to the rotor. A spindle is positioned to be non-rotating and has a drive connection with the nut. A piston rod has one longitudinal end fixed to the spindle, with the spindle extending coaxial to the piston rod. The spindle is driven by the nut in response to rotation of the rotor so that the piston rod executes a linear movement controlled by the electric motor.
