An AC motor can be simple to use, but its speed changes according to the size of the load or amount of voltage supplied. For an application where keeping a uniform speed is important, there is another type of motor that can improve performance.
Welcome to Oriental Motor's "Engineering Notes" Blog:

The BLH Series compact BLDC motors and drivers have been around for a long time, and there is a good reason. Customers seem to favor the combination of a highly efficient, compact motor and a light weight board type driver that is easy to use. Having a high torque, flat style hollow shaft gearhead as an option also helps in increasing torque as well as minimizing footprint.
Are you using motors for a start/stop conveyor or similar application? While AC motors are a common choice for conveyors, there is a unique speed control motor solution available that could improve stop accuracy as well as reduce footprint and cost of machine designs.
What motors do you use for pumps? For variable speed pump applications that typically use 3-phase AC induction motors with variable frequency drives (VFDs), there is another type of motor that can transfer fluids more consistently and help reduce footprint.
Historically, worm gears have been known as the most common type of gears used in a right angle gearhead. Their low cost and robust construction have been sufficient for general purpose applications. However, they are inefficient at slower speeds (higher reduction ratios), produce a lot of heat, take up a lot of space, and require maintenance. As efficiency standards became increasingly important globally, another type of gear is being adopted for right angle gearheads.
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.
The MEXE02 support software is a universal motion control and monitor software used with many products from Oriental Motor, such as the stepper motor drivers from AZ Series, AR Series, and RK2 Series, or brushless DC motor drivers from BLE2 Series and BX2 Series. This post is useful for first-time users to gain a quick understanding of the software and what it can do.
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.

Robotic grippers are typically used to grip parts for transport. The driving force behind a gripper can be pneumatic, hydraulic, or electric. Which type is best for gripping?
