3x NEMA 34 - 150 oz in Stepper Motors
Three NEMA 34 motors, with 3/8" shaft. Motors are un-used and run smoothly without resonance in the full operational range. Rated 150 oz. in. Top speed is 24,000 pulses per minute, which equals 120 rpm, no load condition. Torque is excellent all the way up to top speed. As an example, if your system has an accuracy of 1000 steps per inch, that would equate to a travel rate of 24 inches per minute. Motors can be run from 5v without power resistors or 12v with power resistors (included). 
Hi Torque at Top Speed is achieved by over-voltaging the motors with current-limiting power resistors to keep current at the desired level. Power resistors have been selected to produce a drive current of 20% greater than motors rated current. The resistors do get hot and must be mounted to a heat sink. (Heat sink is not included, a simple sheet of metal will do.) These aluminum frame resistors include mounting holes. Heavy Duty Power Supply included. The power supply has both 5v to drive chip logic and 12v with more than enough current to drive all 3 motors in HI TORQUE mode simultaneously. Motors can be run from 5v without power resistors or 12v with power resistors. AC power cord included. (Power Supply Rating: 400 Watt. 5v@20Amps, 12v@12 Amp)
Uses a step/direction interface compatible with 3rd party Stepper/CNC software. This project comes with a variety of software on CD, including Stepperworld programs to exercise the system and Demo/Shareware versions of popular CNC software.
The QBASIC software allows you to control the motors using the keyboard or gameport joystick. Easy to follow, written with the beginning programmer in mind. Original software written by Stepperworld. You can single-step the motors, one pulse at a time both forward and reverse, or run them continuously (forward and reverse). The rate of revolution is smoothly variable - QBasic software allows sample rates up to 600+ Hz (depending on the clock speed of your PC's cpu).
VBStepDir.exe - 3 Axis Control Panel VB6 Windows Control Panel In addition to the free QBasic source code described above, you receive a 3-Axis Stepper Control Panel, which allows you to control your 3 axis system from Windows 95/98/2000/XP. Select the Parallel Port address and click Start/Stop. You can change the rate, and direction of rotation from this panel using the mouse or keyboard. Stepping is synchronized to a high-resolution millisecond timer. OPTIONAL: Source to the VB6 Windows Control Panel is an additional $20. (The source is not required to run the Windows control panel.) This application demonstrates Stepper Control, Port I/O, and a High-Resolution Millisecond timer. Documentation and Stepper Tutorials Documentation includes connection diagram, setup & interface information, and a tutorial on Stepper Motors.
