DC Linear Motor:
A DC 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. The rotor with permanent magnets becomes the stationary part of the linear motor, it also called the secondary, or magnet plate. The stator which contains the coil windings, becomes the moving part, it also called the primary, or coil unit.
DC Linear Actuator:
A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. These actuators find applications in various industries, including machine tools, industrial machinery, computer peripherals, valves, dampers, and more, wherever linear motion is essential.
