Generally speaking, one of the commonly used methods to achieve precise linear positioning is to make a set of linear positioning system by pairing the motor with the sliding bar. Here we will discuss several different ways to create a linear actuator by using the sliding bar and stepper motor. The stepper motor is the most commonly used selection in the application of motor control because if the operation is correct, it is an economic solution that can achieve accurate positioning without the need of position feedback.
Stepper linear actuator can be divided into three types, external shaft type, non-captive shaft type and captive type.

As equipment to disconnect load power, selection of contactor should meet requirements of controlled equipment. Except that the rated operational voltage is the same with the rated operational voltage of controlled equipment, load power, usage category, control mode, operation frequency, working life, installation method, installation dimension and economy of controlled equipment are the basis of selection. How to choose a right contactor? The principles are as follows:

In the family of gearboxes, the planetary speed reducer or gearbox is widely used in transmission systems such as servo motors, stepper motors and DC motors due to its small size, high efficiency, wide deceleration range and high precision. In the premise of ensuring the precision transmission, it is mainly used to reduce the speed, increase torque and reduce the inertia ratio of the loads or motors. Thus, how to choose a right planetary speed reducer or gearbox to fit a motor?
