More Information

Overview Manuals Applications Environmental Ratings Performance Integration

Features:

  • Uses a 12 V RMS, 2500 Hz stator excitation with a 0.50 transformation ratio.
  • Provides seven-arc-minute maximum angular error in the documented execution.
  • Uses the model-specific 0.1200 x 0.300 in shaft and six PTFE leads.
The resolver provides rugged analog angular-position feedback in compact machinery where environmental sealing is not required and a compatible control-transformer decoder is available.

A sinusoidal reference excites the stator and the rotor position changes the coupled sine and cosine relationship. A compatible resolver decoder calculates shaft angle from the ratiometric output, rejecting common changes in excitation and component characteristics.

Route the six resolver leads as documented and terminate cable shields only at the resolver decoder. This control-transformer model is not compatible with AMCI interfaces intended only for transmitter-type resolvers.

Availability is reviewed against the exact R11W-F10/7-2 order identity and requested supply condition; manufacturer lifecycle status: Active / Available from OEM.
Verified resources for AMCI R11W-F10/7-2:Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • The -2 mechanical execution uses the exact 0.300 in shaft length shown on AMCI sheet 940-2T480. It must not be replaced solely by the otherwise similar R11W-F10/7 drawing with a 0.500 in shaft.
  • The small shaft requires a flexible coupler to avoid excessive radial or axial loading. The resolver body is intended for space-critical servo, machine-axis and positioning assemblies.
  • Requires a compatible control-transformer decoder and a flexible shaft coupler.
  • NEMA 1 enclosure suits protected indoor machinery without environmental sealing.
  • Rugged resolver feedback supports positioning where optical encoders are unsuitable.
  • Ratiometric sine and cosine outputs reduce sensitivity to excitation variation.
  • Maximum stated angular accuracy error is seven arc minutes.
  • Control-transformer winding differs electrically from transmitter-type resolver designs.
  • Accepts a 12.0 V RMS, 2500 Hz stator excitation.
  • Six resolver leads must follow the documented control-transformer wiring diagram.
  • Cable shields terminate at the resolver decoder to control electrical noise.
  • Nominal 6.00 V RMS output requires a compatible resolver-decoder interface.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why is AMCI R11W-F10/7-2 suited to compact position feedback?
The resolver provides rugged analog angular-position feedback in compact machinery where environmental sealing is not required and a compatible control-transformer decoder is available.
Which specified electrical excitation must drive AMCI R11W-F10/7-2?
The manufacturer data specifies Input as 12.0 V RMS at 2500 Hz; stator primary; the installed arrangement must match that exact value.
How does AMCI R11W-F10/7-2 encode the connected shaft angle?
A sinusoidal reference excites the stator and the rotor position changes the coupled sine and cosine relationship. A compatible resolver decoder calculates shaft angle from the ratiometric output, rejecting common changes in excitation and component characteristics.
Why must AMCI R11W-F10/7-2 use a compatible decoder?
Route the six resolver leads as documented and terminate cable shields only at the resolver decoder. This control-transformer model is not compatible with AMCI interfaces intended only for transmitter-type resolvers.
What availability review is appropriate for AMCI R11W-F10/7-2?
The page records Active / Available from OEM. Apter Power reviews the exact order identity and condition without presenting this as an OEM delivery promise.
Which shaft and accuracy details define an AMCI R11W-F10/7-2 request?
Submit the complete nameplate, Maximum accuracy error (7 arc minutes), installed system evidence, condition, quantity and destination so the document and quotation match R11W-F10/7-2.
