AMCSTI - NeverStall Stepper Motor Controller vs Standard Driver/Controller

A brief demonstration of Source Twos Advanced Stepper Motor Controller technology (on the right). The motors are identical Detech NEMA 34 rotary steppers; standard controller technology is shown on the left. The purpose of the fixture is to see and feel the difference between the 2 technologies. Its a difference that you can hear and feel.

Both stepper motors are receiving equal current and being run at approximately the same speed. The motor on the left is running like a stepper while the motor on the right behaves like a BLDC. The end result is higher speed with higher torque, quieter operation, very low resonance, no stalling and energy efficient operation. Modes include Velocity, Torque and Position and other based on customer requirements.

More to come..

Yes there is an encoder in play! thank you for your comment.

[mootness]

Thank you for comments - Availability at this point is based on application. We have product design in the queue for single axis drive/controller that can easily be incorporated into equipment design. We do have original bread board "kitchen sink" controller available, but it has a lot of extra features that might not be required.

is it possible to buy your drive yet?

[stamy1666]

Do you know anybody about this technology? Is there some company to shell that type of drives?

Please let me know

MY STEPPER MOTOR IS VERY SLOW WAT I DO . MAE HY200 2220 0062 AC04 VMax84V 0.62A/Ph

Very nice~! is there encoder or something in right stepper motor ?

[adisharr]

@CLAUDIOPEIXOTO Yes - there are also a few other manufacturers that have similar stepper technology.

@ZNahum81208 It's much more sophisticated than that. You might notice that the closed loop motor doesn't slip. It detects when it's about to stall and modifies the commutation to prevent slipping. Typically these types of systems run smoother as they only draw the required current to keep from slipping.

This isn't AMCI related - AMCSTI is the acronym for "Advanced Motion Control Source Two Inc." Current status - going quite well!

Whats the status of this? Doesnt seem to be anything up on the AMCI website.
