Brushless DC Electric Motor - Applications - Industrial Engineering - Positioning and Actuation Systems
... Brushless motors are used in industrial positioning and actuation applications ... For assembly robots, brushless stepper or servo motors are used to position a part for assembly or a tool for a manufacturing process, such as welding or painting ... Brushless motors can also be used to drive linear actuators Actuators that produce linear motion are called linear motors ...
Linear Induction Motor - History
... The history of linear electric motors can be traced back at least as far as the 1840s, to the work of Charles Wheatstone at King's College in London, but Wheatstone's model was too inefficient to be practical ... A feasible linear induction motor is described in the US patent 782312 ( 1905 - inventor Alfred Zehden of Frankfurt-am-Main ), for driving trains or lifts ... These versions of the linear induction motor use a principle called transverse flux where two opposite poles are placed side by side ...
Linear Actuator - Types - Electro-mechanical Actuators - Linear Motors
... A linear motor is functionally the same as a rotary electric motor with the rotor and stator circular magnetic field components peeled off and laid ... Where a rotary motor would spin around and re-use the same magnetic pole faces again, instead the magnetic field structures of a linear motor are physically repeated across the length of the ... Since the motor moves in a linear fashion to begin with, no lead screw is needed to convert rotary motion to linear ...

Famous quotes containing the word motors:

    When General Motors has to go to the bathroom ten times a day, the whole country’s ready to let go. You heard of that market crash in ‘29? I predicted that.... I was nursing a director of General Motors. Kidney ailment, they said; nerves, I said. Then I asked myself, “What’s General Motors got to be nervous about?” “Overproduction,” I says. “Collapse.”
    John Michael Hayes (b. 1919)
