Welcome to Oriental Motor's "Engineering Notes" Blog:

In high-precision automation environments like semiconductor manufacturing, even the smallest error can result in costly defects and downtime.   What if you could deliver servo-like precision without the complexity or cost of servo motors?

CVD Series stepper drivers are the best choice for PKP Series high-torque stepper motors due to their unique abilities to reduce different types of motor vibrations and optimize performance.

A network-compatible multi-axis driver can save space and reduce costs by combining multiple stepper motor drive circuits in a single product and minimizing the number of cables necessary for motion control.

Thinking about building your own stepper motor driver?   This article explains the process of designing and building your own stepper motor driver compared to purchasing one.

An easy way to alter the speed and torque characteristics of a stepper motor is to connect it to a different type of driver or change its wiring configuration.  However, there's more to it.  Knowing the pros and cons between "unipolar" and "bipolar" can make or break your stepper motor performance.

Stepper motors vibrate.  It's what they do.  To minimize motor vibration, first we need to understand where they come from.

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.

Standard Stepper Motor System Configuration

There are many stepper motor manufacturers in the market place, but there are even more stepper motor driver manufacturers.  The crowded market place provides many standard product options for customers to build their motion control system just the way they like it. 

However, if the best possible performance is desired, it would be difficult to beat a tested combination of a specific motor and driver from the same manufacturer.  By combining R&D knowledge from both motors and drivers, unique product features can be developed to improve performance further.
