2 Phase Brushless DC motor control

Hi,

I have a 2 phase brushless dc motor that uses about 28 VDC and 1-1.3 Amps. Attached to the output shaft is an optical encoder that is very accurate (down to arcseconds... it's the BEI AIME-II encoder). The motor has 2 wires that go to ground and then 1 wire that should be supplied with a sine wave and the other with a cosine wave (hence 2 phase). I need to do position and velocity control on the motor (i.e. command it to a certain angle or angular rate), and also possibly acceleration control. Is there something I can purchase that will do what I need? Or maybe a few things I can put together? I am very new to working with motors, and this is way out of my realm of expertise. My boss said he would like to be able to send the position and velocity control commands via simulink.

Thanks,

Dustan

Hi Dustan,

This thread is being merged with the first post.

Hi Dustan,

Can you provide a motor specification? This will help determine potential devices that may work.

Hi Rick,

Is this what you are looking for? I have circled our specific motor's specifications in red. Also, I have attached the original pdf where the screenshot above came from. The pdf has more information about the motors. motion-motors-zerocogging.pdf 

Thanks,

Hi Dustan,

I have not been able to definitively find a device that works. We have 3 phase drivers, but I don't know enough about this motor to say the 3 phase drivers can control it. Do you have any additional information to show how the motor is driven?

Hi Rick,

What information could I provide that could help you?

Thanks,

Dustan

Hi Dustan,

Can you provide a specification or existing product that describes how to control the motor? Without this information, we can only point you to devices that may work.
