Stepper, Servo, or Rotary Switch? Motion Control Choices From $25 to $799

Four motion-control options range from a $25 used rotary switch to a $799 open-box Schneider stepper motor. This guide compares two identical Schneider entries, an Omron AC servo driver, and a Candy rotary control to help you pick the right part for your line.

Last updated Aug 17, 2026

Choosing industrial motion control usually starts as a budget exercise, but it should start as a type exercise. A stepper motor, an AC servo driver, and a rotary switch do very different jobs. The four options considered here span $25 to $799, and two of them are actually the same Schneider stepper motor at different prices. Your decision comes down to what the machine needs to do: rotate a switch, drive a stepper axis, or power a servo axis.

Quick take

If your line needs a stepper motor, the lower-priced Schneider LMHAE572C option is the stronger pick, because it matches the higher-priced version in model and condition. If you need an AC servo driver, the new Omron R7D-ZP02H is the dedicated choice. If the task is a simple adjustable rotary switch for industrial control, the used Candy Model C is the low-cost entry point.

Price comparison

OptionListed pricePrice barWhat you are choosing
New Schneider Electric LMHAE572C Industrial Motion Control Stepper Motor USAUSD 799.00New open-box Schneider stepper motor; same model as the $325 entry
New Schneider Electric LMHAE572C Industrial Motion Control Stepper Motor USAUSD 325.00New open-box Schneider stepper motor at the lower price of the pair

New Omron AC Servo Driver R7D-ZP02H Industrial Motion Control UnitUSD 506.00New AC servo driver with 325 VDC/20 A bus input

Reading the price spread helps make the choice. The $25 option is a rotary switch, the $506 option is a servo driver, and the $325 and $799 options are the same stepper motor. In other words, the range is not a quality ladder; it is a function ladder. Pick the function first, then let price separate the duplicates.

Decision matrix

  • Stepper motor need: The two Schneider LMHAE572C entries are stepper motors. The only meaningful difference between them is price, not the motor.
  • Servo driver need: The Omron R7D-ZP02H is an AC servo driver. If your motion axis already has the motor side covered, this is the driver to look at.
  • Rotary control need: The Candy Model C is a rotary industrial motion control switch. It is not a motor or driver, so it works best as a control input or adjustment point.
  • Condition: The Schneider and Omron units are new; the Schneider units are open-box, and the Candy switch is used.

Product notes

New Schneider Electric LMHAE572C (USD 799.00)

New Schneider Electric LMHAE572C Industrial Motion Control Stepper Motor USA

This entry anchors the top of the price range. It is the same Schneider LMHAE572C stepper motor as the lower-priced version, described as new, unused, and open box, with the United States as the country of origin. If your purchasing situation requires a higher-priced quote for this exact motor, this option gives you that reference point. The limitation is that there is no hardware difference from the lower-priced version. You are paying much more for the same model, same condition, and same origin. Choose it only when your process needs the higher price point; otherwise the lower-priced entry is the same part.

New Schneider Electric LMHAE572C (USD 325.00)

New Schneider Electric LMHAE572C Industrial Motion Control Stepper Motor USA

This is the same Schneider LMHAE572C stepper motor described as new, unused, and open box, also with US origin. For most stepper-motor projects, this is the more practical pick because it carries the same model and condition as the higher-priced version without the extra cost. The limitation is the open-box wording: the motor is new and unused but it does not come with its original box. If your receiving process requires retail packaging, this option will not provide it. Choose it when you want the Schneider stepper motor and can accept an unpackaged unit.

CANDY CONTROLS SWITCH Adjustable Model C (USD 25.00)

CANDY CONTROLS SWITCH Adjustable Model C rotary industrial motion control

This used Candy rotary switch is the lowest-cost way into this set. It is an adjustable Model C industrial motion control made in the United States, with a rotary switch style. If the machine already has its own motion source and you need a manual, adjustable control, this part fits that role without the expense of a motor or driver. The limitation is that it is used, and it is not a motor or driver, so it cannot generate motion on its own. Use it where a rotary switch is the right control interface, not as a stand-in for a powered axis.

New Omron AC Servo Driver R7D-ZP02H (USD 506.00)

New Omron AC Servo Driver R7D-ZP02H 1PC Industrial Motion Control Unit

This new Omron unit is the only AC servo driver in the group. It is built for the driver side of a servo axis, with AC current type, a 325 VDC/20 A bus input, and a Kinetix controller platform. If your system already has a servo motor and needs the driver to complete the loop, this is the dedicated component to start with. The limitation is that it is not a stepper motor or a standalone motion device; it needs the rest of the servo axis before it produces movement. Choose it for AC servo driver duty, not for a simple stepper-motor replacement.

Final recommendation by use case

  • Stepper motor need: Go with the lower-priced Schneider LMHAE572C. It is the same motor as the higher-priced version, so there is no hardware reason to pay more.
  • AC servo driver need: Go with the new Omron R7D-ZP02H. It is the only driver type in this set and it is a new unit.
  • Rotary control need: Go with the used Candy Model C. It is the lowest-cost part and it matches an adjustable rotary switch application.
  • Price ceiling reference: The higher-priced Schneider LMHAE572C marks the top of the $25-to-$799 range if you need to understand the spread.
