CVD stepper motor driver with RS-485 Communication

February 19, 2021 By Kelsey Zebrowski Leave a Comment

Oriental Motor is pleased to introduce latest driver added to DC input stepper motor driver line up, the CVD RS-485 Communication type bi-polar drivers. The CVD driver is a compact standardized 24 VDC driver providing the lowest noise and vibration available through the fully digital full-time microstepping control circuit. The CVD drivers can be used […]

Swiss precision motors handle valuable Mars soil samples

February 18, 2021 By Danielle Collins Leave a Comment

maxon precision motors

Was there once life on Mars? This is the question that one of the most complex robotic systems ever built by humankind has set out to answer. Several of maxon’s electric drives are used for handling the soil samples — and to control the first Mars helicopter. The rover named Perseverance entered the atmosphere of […]

What is field weakening and how does it affect servo motor performance?

January 28, 2021 By Danielle Collins Leave a Comment

Although servo systems can very precisely control motor speed, position, and torque, in some applications, the motor may not be able to reach the commanded velocity due to limits in the available bus (supply) voltage from the drive. But advanced servo drives offer a technique referred to as field weakening, which alters the motor’s torque-speed […]

What is friction compensation in servo control?

January 19, 2021 By Danielle Collins Leave a Comment

Friction, which is the resistance to relative motion between two bodies, occurs in all sliding and rolling motions. In components that use lubrication to separate rolling or sliding surfaces — such as bearings and gears — there are typically two types of friction: static friction and dynamic friction. Static friction — also referred to as “stiction” […]

Feedback on stepper motors for better positioning and holding (and less ringing)

January 15, 2021 By Lisa Eitel Leave a Comment

Feedback-equipped stepper motors are not a complete substitute for servomotors, but they can provide a reliable alternative for many real-world applications. These motion-design solutions improve machine performance without breaking the bank. By Jim Stevens • Product Specialist | POSITAL Inc. Stepper motors are a top choice for many motion and position control applications. They’re available […]

How to size an electric-motor-driven chain-and-sprocket system

January 13, 2021 By Lisa Eitel Leave a Comment

In previous motion-sizing articles, we reviewed how to properly specify (using software) a ballscrew-driven motion axis. Then we reviewed how engineering teams can use a similar software-based approach for sizing rack-and-pinion-based servomotor-driven axes on the same five-axis gantry. Now we’ll explore the process for sizing the components (using that same software) for an electric-motor-powered axis […]
