1699 oz-in 12Nm NEMA 43 Stepper Motor

159.80

Introduction:

This stepper motor has a large frame size and torque and can be used where a great amount of weight is carried and where high load against the motor turning direction is present.

Description:

A single shaft motor with a diameter of 14mm or .55 inches. There is a keyway on the shaft. The motor rated torque is 1699 oz-in or 12 Nm (Newton Meters). This is a very strong motor which will provide enough torque for heavy gantries and high acceleration.

Wiring: Black to A+, Green to A-, Red to B+ and Blue to B-

Steps:Standard 200 steps per rotation and can be microsteped using drivers that feature microstepping. The degree per step is 1.8.

Size:NEMA 34, or 3.4 x 3.4 inches outer frame (face) dimension or 86mm x 86mm. The length of the motor not including the shaft is 151mm. The length of the shaft is 37mm. The mounting dimension is 70mm.

Electrical:Amps per phase is 6.0 amps

[NEMA 34 Stepper Motor (1699 oz-in 14mm single shaft) 6 Amps] Is this a closed loop motor? What is the recommended driver and power supply for this stepper? Would you recommend using one power supply per motor pair or one power supply per motor?

That depends on a few factors. In most cases, three 3.0 amp motors and drivers will not exceed 8.8 amps of available current. All of the motors would need to be at full torque to reach the 9 amps (3x3). This depends on the mechanical method you are using for each motor, and how you are using the machine. In most cases, only two motors are moving at a time (i.e. 3D carving where the X and Z are moving simultaneously and the y only moves to go to the next row). In traditional cutting profiles, only the x and y are moving simultaneously and the z-axis moves at the location it needs to start cutting the next layer.

With that said, it is ok to add an extra power supply if you feel you need more available current.

I came across a rather interesting idea while checking out Disney's Research Hub: Printed Optics. They seem to be quite interested in fabrication and 3D printing as a good majority of their videos pertain to this type of subject matter. More interestingly, they have devised a way to print objects that embed optical characteristics so that light traverses where they intend to create some very interesting effects.
