Using This Manual
The Accuriss Series is a unique motor, drive and control all in one package. The USA57 is the
57mm version in this series and it is designed to be interactively controlled with a computer or
other industrial controller or may be preprogrammed to run complex subroutines from programs
stored in non-volatile RAM.
This manual provides the basic information necessary to unpack, set up, and configure the
USA57. If additional information is required beyond what is presented here, please refer to the
Support section of our website or contact USAutomation Applications Engineering.
Product Returns
All returns for warranty or out-of-warranty repairs must first receive an RMA (Return Material
Authorization) number. Please contact USAutomation Customer Service Department with
information about the return and an RMA number will be issued if warranted.
Products returned to the factory will be examined and tested for failure mode and cause.
USAutomation Customer Service will contact the customer with the repair cost if the required
repair is out of warranty.
Unpacking
Carefully remove the USA57 from its shipping box and inspect the unit for any evidence of
shipping damage. Report any damage immediately to USAutomation. Please save the shipping
box for damage inspection or its use in returning product if necessary.
Please observe the following guidelines for handling and mounting of your USA57:
Do not drop the unit on any hard surface or subject it to any impact loads. Dropping the
unit or other impact loads may result in bearing damage or misalignment.
Do not drill holes into the motor. Drilling holes into the unit can generate particles and
machining forces that may affect the operation of the unit. USAutomation can supply the
USA57 with modifications to your drawing. Please contact the factory for a quote.
Do not expose the USA57 to mist, spray or submersion in liquids.
Do not disassemble the USA57. Unauthorized adjustments may alter the specifications
and void the product warranty.

Mounting the USA57
Threaded mounting holes are located on the front of the Accuriss 57. There are four thru holes
with a 0.200 in. diameter. See Dimensions section for exact locations.
Mounting a Load to the USA57
The Accuriss 57 has 0.250 in. diameter shaft for mounting the load (see dimensions page).
Care should be used in isolating the motor bearing from thrust and axial loads. It is not
advisable to couple loads to the Accuriss shaft with a solid coupling as that may impose radial
loads on the motor bearings which will shorten the life of the motor. A flexible coupling, such as
those made by Helical (www.heli-cal.com), should be used.
USA57 Revision 1.2 10
Speed Torque Curves
The base motor for the USA57 is a 1.8°/step 2-phase hybrid step motor. Full torque will be
available from the motor when used with a drive which has a rated output of at least 2.0 amps
per phase. Here are representative speed/torque curves for the two different lengths of motors
available. Individual applications may differ in motor performance:
