A traveling-nut linear actuator has a motor that stays attached to one end of the lead screw (perhaps indirectly through a gear box), the motor spins the lead screw, and the lead nut is restrained from spinning so it travels up and down the lead screw. A traveling-screw linear actuator has a lead screw that passes entirely through the motor.
This is not always the case in non-linear circuits. For instance, a linear resistor with a fixed current applied to it has only one solution for the voltage across it. On the other hand, the non-linear tunnel diode has up to three solutions for the voltage for a given current. That is, a particular solution for the current through the diode is ...
Without using moving parts, they are called solid state switches, which distinguishes them from mechanical switches. [ 1 ] Electronic switches are considered binary devices because they dramatically change the conductivity of a path in electrical circuit between two extremes when switching between their two states of on and off .
Then a linear stepper motor of the variable reluctance type was for serial printer applications. In 1977 J.W. Finch researcher on the Linear Vernier Reluctance Stepper Motor to replace a mechanical conveyor for a trolley. In 1988-89, Takamaya developed a linear motor based on the principle of variable reluctance.

A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.
We are just days from the Indianapolis 500 and the starting grid is set.. After two days of qualifying, Scott McLaughlin earned the pole position at 234.220 mph for his 4-lap run around the 2.5 ...
