Along with the advancement of industrial technology, maintenance methods of motion control components of a machine, such as motors, drives, and sensors, have also evolved. Which method is the most efficient?
The most common method of maintaining a machine after a failure has occurred was the traditionalreactive maintenancemethod. Realizing the need for improvement, maintenance personnel started to estimate life and replace motion control components before they fail. This is called the preventive maintenancemethod. More recently, with the advancement of IIoT (Industrial Internet of Things) and real-time availability of status data, another method was born - the predictive maintenance method.
The three maintenance methods have the same goal of eliminating machine downtime but do it differently.

Robot adoption is increasing in many industries due to global efforts in reducing long term costs, maintaining quality, and freeing up time for humans to do "human" tasks. For example, by using a robot to clean floors or restock shelves in a supermarket, human employees can spend more time helping or selling to their customers. A company can either tap into this robotic trend by buying ready-made robots, or by making their own with less cost.
If engineering resources are limited, selecting the right components can reduce the difficulty and time for building a robot.

There are many mechanisms that convert rotary motion of an electric motor to linear motion, such as belt/chain drives, screw drives, rack & pinion drives and even CAM drives. Each mechanism offers advantages and disadvantages. Choosing the right technology can help increase load, speed, travel distance, or positioning accuracy.

In the world of industrial robotics, there are several types of robots typically offering multiple axes of motion for tasks such as parts assembly, material handling, or pick and place operations. These include articulated robots, cartesian/gantry robots, SCARA robots, and Delta robots. Variations of end effectors such as grippers, welders or part rotators can be mounted on the end of the arm to perform different tasks. Depending on number of axes or load capacity, costs can easily add up. Limiting the operation range for these robotic axes of motion is an easy way to prevent costly problems or safety issues later.

For applications where torque needs to be limited, an external mechanical torque limiter is typically required in addition to the motor system. When the torque exceeds the limit, the torque limiter will either decouple the load or limit the torque by slipping. An electric motor system's built-in torque limit function can simplify machine designs by eliminating this extra component.

A driver is a must-have for any stepper motor. In a stepper motor system, a driver controls how the motor operates based on signals received from the controller. It is responsible for sending current through various phases in a stepper motor and also regulates the motor current (torque) and step resolution. With recent trends of minimizing machine footprint, finding space to install drivers could be challenging.
