Gemco resolver replacement options from Autotech Controls
Searching for a Gemco resolver replacement or a Gemco 1986 resolver alternative? Compare both the electrical characteristics and the mechanical package. Autotech offers industrial brushless resolvers in several mounting and application configurations; the correct selection depends on the connected controller and the machine installation. [1]
Electrical and mechanical compatibility require verification for the exact part number. Special environment ratings must be checked for the selected model.
What to evaluate with Autotech
Gemco 1986 resolver replacement checklist
| Selection point | Gemco reference | Autotech evaluation |
|---|---|---|
| Mechanical package | Gemco 1986 includes multiple mounting configurations and shaft sizes. [2] | Match the drawing, shaft diameter, mounting pattern and coupling. |
| Electrical output | The 1986 family offers different resolver electrical selections. [2] | Confirm excitation, transformation ratio and controller input requirements. |
| Single or multi-turn | Gemco lists single-turn, geared and dual resolver configurations. [2] | Match the position range, gear ratio and fine/coarse channel arrangement. |
| Connection | Identify the exact connector and installed cable pinout. | Check the wiring diagram and shielding; connector fit alone does not establish compatibility. |
| Environment | Identify whether the installed unit has special enclosure or environmental requirements. | Choose the appropriate Autotech configuration and verify its published ratings. |
Why the complete resolver part number matters
A family name such as “1986” does not identify every characteristic of a resolver assembly. Photograph the complete nameplate, connector and mounting arrangement. If the device works with an existing controller, include that controller’s model and wiring diagram. If the project also replaces the controller, evaluate the controller and resolver together rather than assuming the original feedback device must be retained.
Review Autotech industrial resolvers specifications →Frequently asked questions
Can any Autotech resolver replace a Gemco 1986?
No universal interchangeability is established. The electrical selection, mechanical dimensions, gearing and environment must match the application.
Can I retain the existing Gemco controller?
That depends on the selected resolver’s electrical characteristics and the controller’s feedback requirements. Include the controller part number in your compatibility request.
Does a matching connector mean the resolver is compatible?
No. Confirm the pinout, excitation, output characteristics and shielding before connecting the replacement device.
What if the resolver label is unreadable?
Send photographs of the housing, shaft, mounting and connector, along with the controller model and any machine documentation. These provide a starting point for identification.
