The HV motors are the best choice for replacing the ES motors, offering higher torque, better lead times and more competitive pricing.

This chart shows the ES motor with shared characteristics along with the recommended HV replacement.
See the notes column and associated footnotes that summarize mechanical differences.

Notes for selecting HV as replacements:

1) HV23x motors have the same face mounting, shaft length and shaft diameter (0.25inch)
2) ES2x and HV23 motors do not include a connector
  • HV23x-02-10 : Double shaft with a single flat
  • HV23x-01-10 : Single shaft with a single flat
  • HV23x motors are not available with keyways
  • -E or -EC models include a 1000 lines encoder. HV23x motors can be supplied with a similar 1000ppr encoder.
