A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque , it produces a linear force along its length. However, linear motors are not necessarily straight.

2025年1月5日 · Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. In a traditional electric motor, the rotor (rotating part) spins inside the stator (static part); in a linear motor, the stator is unwrapped and laid out flat and the "rotor" moves past it in a straight line.

2024年1月23日 · Linear motors are devices that directly convert electrical energy into linear mechanical motion without any intermediate conversion mechanisms. They can be thought of as rotary motors that have been cut radially and unfolded into a flat plane.

What is Linear Motor? A linear motor is an electric motor that generates motion in a straight line, rather than rotating. It works by using magnetic fields to create direct linear movement.

Electric linear drives are replacing conventional pneumatic cylinders in more and more applications. The reasons include poor efficiency, high costs for commissioning, reconfiguration, service, and maintenance, and the limited control capabilities of pneumatic systems.

The short answer is that linear motors are better for fast motion, acceleration, and very high accuracy, while ball screws and linear actuators offer higher force and lower cost.

2017年3月13日 · A linear motor is an electric motor that does not generate a rotary movement but a linear one. Unlike rotary motors, a linear motor moves the element along a linear or curved path. The most common mode of operation is as a Lorentz type actuator. In this mode the applied force is linearly proportional to the electric current and the magnetic field.

2012年2月24日 · A Linear Induction Motor (or LIM) is a specialized induction motor engineered for straight motion instead of the rotational movement typical of standard motors. These motors modify the traditional design to serve unique functions while maintaining a similar working principle, increasing their operational versatility.

Linear motors are a kind of electric motor that produces motion in a straight line. The same laws of electromagnetism that regulate rotary motors are responsible for this direct linear motion; nevertheless, the layout and operation of the two types of motors are fundamentally different.

Linear motors offer several advantages over belts, screws, and other drive mechanisms, including virtually unlimited lengths, low maintenance, and higher accuracy and repeatability.
