A linear motor or linear induction motor is essentially a multi-phase alternating current (AC) electric motor that has had its stator "unrolled" so that instead of producing a torque (rotation) it produces a linear force along its length. The most common mode of operation is as a Lorentz-type actuator, in which the applied force is linearly proportional to the current and the magnetic field (F = qv × B). Many designs have been put forward for linear motors, falling into two major categories, low-acceleration and high-acceleration linear motors. Low-acceleration linear motors are suitable for maglev trains and other ground-based transportation applications. High-acceleration linear motors are normally quite short, and are designed to accelerate an object up to a very high speed and then release the object, like Roller Coasters. They are usually used for studies of hypervelocity collisions, as weapons, or as mass drivers for spacecraft propulsion. The high-acceleration motors are usually of the linear induction design (LIM) with an active three-phase winding on one side of the air-gap and a passive conductor plate on the other side. The low-acceleration, high speed and high power motors are usually of the linear synchronous design (LSM), with an active winding on one side of the air-gap and an array of alternate-pole magnets on the other side. These magnets can be permanent magnets or energized magnets. The Transrapid Shanghai motor is an LSM.
The torque motor works the same way a synchronous motor works. Magnets are attached on the inner surface of a drum, and a strator is present consisting of magnetic coils that are integrated via an iron matrix. These coils provide three-phase current and are star-switched.
An electric pencil sharpener works by means of a small electric motor. The motor rotates the blades, sharpening the pencil.?æ
A servo motor is an electric motor with a built in rotation sensor, they are needed for robotics. Say a robot moves its arm by turning a servo motor, the motor would send information concerning the degree of rotation on its axis back to the robot so the robot can keep tabs on the position of its arm, so if something bumps its arm it will know it and so-on.
A DOL or direct on line starter works by connecting the motor terminals directly to the power supply when they are energized. A DOL starter is the simplest type of motor starter.
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis
The linear induction motor works on the same principle as that of normal induction motor with difference that instead of rotational movement, the rotor moves linearly. If the stator and rotor of the induction motor are made flat then it forms the linear induction motor. The flux produced by the flate stator moves linearly with the synchronous speed from one end to the other. The synchronous speed is given by, v s = 2wf where v s = Linear Synchronous Speed (m/s) w = Width of one pole pitch (m) f = Frequency of supply (Hz) It can be seen that the synchronous speed is independent of number of poles but depends only one width of pole pitch and supply frequency.
Only the sweep is linear cylinder. Motor rotates the hydraulic oil pressure.
it works on the basis of conservation of linear momentum
A linear motor car might be describing a long limousine. It might also be describing a car on a train that is used for passenger travel.
how linear voltage differential transducer works?
A linear actuator is a motor controlling motion in a straight line. This is different from a conventional motor where motion is circular. They are most commonly used in industrial machinery, in computer disk drives and printers, and anywhere else linear motion is required.

A linear actuator is a device that creates linear motion, often by converting rotational motion. For instance, an electric linear motor turns a screw that in turn "pushes" a cylinder. By this action, linear motion is created from a rotating shaft.
That is a linear motor.
Yes the Induction motor works on Electromagnetic induction principle.
