This is a permanent-magnet, hybrid, bipolar, 2-phase stepper motor. The shaft protrudes on both sides of the motor. Brass pulleys for toothed belts are press-fit onto both ends of the shaft. The pulleys can be knocked off of the shaft, if so desired, with a hammer and a pin-punch.
Electrical connections are via a 6-pin, single-row, shrouded male header on the motor's body, which mates with a female connector on one end of the included cord. The other end of the cord has a 4-pin female Molex connector (6471 series). This particular motor uses just 4 of the 6 pins.
4 flanged mounting holes, and a precision-machined mounting surface, provide for a wide variety of solid mounting configurations
One satisfied Vetco customer reports success driving this motor with an Arduino microcontroller and Vetco's NTE2996 MOSFETS, to automate the opening and closing of doors to a chicken coop.
A versatile building block, this motor is powerful and precise enough for CNC applications, yet inexpensive enough for everyday experimentation. Vetco's limited supply won't last forever; order several right now.
