What is a linear stepper motor?
The linear stepper motor is rotated by the magnetic rotor iron core through the interaction with the pulsed electromagnetic field generated by the stator. It converts the rotary motion into linear motion inside. Linear stepper motors are widely used in many high-precision requirements including manufacturing, precision calibration, precision fluid measurement, and precise position movement.
Characteristics of Linear Stepper Motors
The linear stepper motor converts the rotary motion into linear motion inside the motor, which is realized by the rotation of the magnetic rotor core through the interaction with the pulsed electromagnetic field generated by the stator.
The conversion of stepper motors from rotary motion to linear motion can be accomplished by several mechanical methods, including rack and pinion drives, belt and pulley drives, and other mechanical linkages. All these designs require various mechanical parts. The most efficient way to accomplish this transition is within the motor itself.
Linear stepper motors are highly durable and maintenance-free. Due to the brushless design of the stepper motor, the only parts that are subject to wear are the rotor shaft and the threaded engagement consisting of the lead screw or nut.
