...
HV23x motors have the same face mounting, shaft length and shaft diameter (0.25inch)
...
S57-xx, ZETA57-xx models include a rubber boot and 9-pin connector pre-wired for a ZETA drive. 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. Request through a local distributor as a custom product. Please note the HV motors with encoder will have a 10 piece MOQ required per shipment and so in many cases if an encoder is required, converting the system to a servo solution may be the better option.
