Zeta, S, ES Series Step Motors Discontinued & Suggested Replacements

Zeta, S, ES Series Step Motors Discontinued & Suggested Replacements

Bulletin SD1471 The S, ZETA and ES series stepper motors were discontinued in 2022.

These were all the same step motors and had a 10-foot cable as standard. The ZETA motor came with a ZETA drive connector on the end (screw-terminal), the S motor came with a S drive connector on the end, and the ES step motor had no connector.

Suggested Replacements

The HV motors are the best choice for replacing the ES/ZETA/S motors, offering higher torque, better lead times and more competitive pricing. Below is a recommended cross-over chart to the closest equivalent HV motor. Rated current of the motor should be reviewed against the available current from the stepper drive. Speed torque curves linked below should be compared to evaluate potential performance differences.

  1. HV23x-02-10 : Double shaft with a single flat

  2. HV23x-01-10 : Single shaft with a single flat

  3. HV23x motors are not available with keyways

  4. -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.

  5. HV34x-02-10 : Double shaft with a double flat

  6. HV34x-01-10 : Single shaft with a double flat

  7. HV34x-04-10 : Double shaft, round

  8. HV34x-03-10 : Single shaft, round

  9. HV34x motors are not available with keyways

  10. 10. -E or -EC models include a 1000 lines encoder. HV34x motors can be supplied with a similar 1000ppr encoder. Request via Extranet Quote system, Custom Electronics
