NEW PRODUCT – Automotive Gauge Stepper Motor – x27.168


This stepper motor is a little different than the large NEMA-17 types you may be used to. These are often used in gauges for motorcycles and cars to replace the old-style fully-analog type. They have extremely fine step precision of about 1/2 a degree per step for single stepping, fast response for quick movements, and a range of  ~315° degrees. Their smooth motion makes good for small projects that need a dial indicator, and more precision motion than you may get with a needle gauge.

Since this is a bi-polar stepper motor you do need to have some sort of H-Bridge to drive it. A L293D or TB6612 will do the job nicely. If you have a microcontroller that can drive 200 ohm loads you might be able to use the direct pins without extra MOSFETs, just remember to include kickback/flyback protection diodes!

Note that the motor is quite ‘weak’, not good for moving anything but a light indicator. We include a red-line dial that fits nicely on top by pushing onto the needle shaft.

  1. Any feedback on the side effects of removing the internal stops to have a 360 degrees rotation? I am interested in that modification, but not sure if it will affect accuracy after that (for sure, will have to work out a way to zero the motor, as I won’t be able to drive it against the stop)

    Thx!!
