Our take on the 34KM-K106-00W Stepper Motor

The 34KM-K106-00W is a NEMA 34 unipolar stepper motor from MinebeaMitsumi, rated 24 VDC and 4.8 A with 200 steps per revolution (1.8° step angle). Its 85 mm square frame, 14 mm shaft and 0.65 ohm coils point to a high-current drive that needs a chopper driver rather than a simple constant-voltage supply. It is an industrial part, not a consumer item, and only one store lists it new: $615.66 at DigiKey as of November 3, 2026.

Best forIndustrial motion and automation builds needing a NEMA 34 frame
High-torque positioning with a current-controlled driver
Replacing a failed 34KM-series motor in existing equipment
Prototyping with unipolar drive electronics
Pros
  • Standard NEMA 34 mounting (69.6 mm hole spacing) fits common brackets
  • 1.8° step angle gives 200 steps per revolution
  • Unipolar coil wiring suits simple six-lead drive setups
  • Wide -10°C to 50°C operating range
  • Active part status, so supply should continue
Cons
  • 4.8 A at 0.65 ohms means high current and real heat; a proper driver is required
  • Single new listing at $615.66, so no price competition
  • Unipolar only; not usable as a bipolar motor without rewiring
  • No holding torque figure published in the listed specs
  • Wire leads only, no connector

Questions and answers

Is this motor worth $615.66?
That is the only new price listed, $615.66 at DigiKey as of November 3, 2026. For a single replacement in working equipment it may be the practical option; for a new design, compare against other NEMA 34 motors before paying a single-source price.
What driver does it need?
It is unipolar, 24 VDC rated and draws 4.8 A with 0.65 ohm coils. Use a current-controlled stepper driver rated above 4.8 A per phase, not a plain 24 V supply.
What is the holding torque?
The listed specs do not state holding torque. Ask the seller for the datasheet before sizing it for a load.
Will it fit a standard NEMA 34 mount?
Yes. The 85 mm square frame and 69.6 mm mounting hole spacing are standard NEMA 34 dimensions, and the shaft is 14 mm.
What comes in the box?
The motor with wire leads. No driver, cable connector or mounting hardware is included.
When is it cheapest?
Only one store prices it new, so there is no comparison to shop. Watch for distributor stock and price changes rather than expecting a sale.
Where is the 34KM-K106-00W Stepper Motor cheapest?
At DigiKey, for $615.66, as of our latest check.
