How fast can Oriental Motor’s AlphaStep accelerate?

Oriental Motor has tested the AlphaStep drives up to 2G’s (64.4 ft/s^2) of acceleration at a frequency of 150 Hz

Using an SB50 Brake Pack with Synchronous Motors.

There is a difference of winding between ACmotors and Synchronous Motors.

Motor                 resistance              resistance
of main winding       of auxikiary winding
3IK15GN-A　          53.5Ω　                 77Ω
3IK15GN-AW　  　 　59.6Ω    　　　　       58.8Ω
3IK15GN-AUL   　 　70.3Ω    　　　　       71Ω
3SK10GN-A     　　  57.6Ω    　　　　      306.8Ω
3SK10GN-AUL   　  71.2Ω    　　　　       234.8Ω

This winding difference makes higher voltage between the terminal of capacitor.
So the rated voltage of synchronous motor’s capacitor is 400WV and ACmotor is 250WV.
And this makes it possible to damage SB50.This is the reason why we don’t recommend
synchronous motor+brakepack.

If the customer must use brake pack with synchronous motor, please recommend SB31-IN with
following connection. This connection is the only way to protect the brackpack with using synchronous motor.

CW
change yellow to gray
change white to light blue
change black,darkblue to black,red,carkblue

CCW
change gray and black

Change the wires to reverse the direction of a 2-phase stepper motor.

Sometimes it’s necessary to mount a stepper motor in a different orientation, or the opposite direction is needed at the motor, but there is no access to the driver control - given the same pulse and direction signals.  Using 6 lead wire unipolar driver, how do I change the wires around to accomplish this?

A: The A-phase lead-wires are normally Black, Yellow, Green.  The B-phase lead wires are normally Red, White, Blue.  To make the motor go in the opposite direction, swap the Black and Red wires, and swap the Green and Blue wires.
