Phidgets NEMA-23 バイポーラ ステッピングモーター 1.8度, 2.8A, 77:1

Very good quality, and very low noise. There is some backlash (2 -3 degrees maybe) from the triple planetary gear reduction when the motor is not running, but it runs smoothly. I used a Stafford 1LM012AFXK Flange mount collar to attach it to 40MM aluminum extrusion. It has a 6 bolt 42MM bolt circle, but 4 of the holes (2, 4,8,10 o'clock) will line up with 40MM rail, so you can mount it with T-nuts you just need to drill out the flange holes. It also has the correct keyway, and a split collar with 2 screws to get a good grip on the shaft.

Very well constructed with lots of torque!!! Exactly what I was looking for. Takes .8 amps with no load. Highly recommended

Utilisé comme activateur d'une vanne de contrôle de pression (0- 4000 PSI), fonctionne a merveille.

Un autre activateur de vanne de contrôle en association avec le un contrôleur de step motor et un encodeur, toujours aussi efficace

Plenty of torque, just make sure you check dimensions twice as they are quite big
