324 a stepper motor to satisfy all your robotics needs. I have included a wiring diagram and many example codes.

Nema 17 stepper motor diagram. It has 4 wires each phase draws current 15a with holding torque 45ncm 6374ozin. In the first example we will look at the stepperh arduino library. Adafruit industries unique fun diy electronics and kits stepper motor nema 17 size 200 stepsrev 12v 350ma id. 5 x 17hs15 1504s x1 electrical specifi. Nema 23 stepper motor wiring diagram wiring diagram is a simplified welcome pictorial representation of an electrical circuitit shows the components of the circuit as simplified shapes and the aptitude and signal friends amongst the devices. This shows that the stepper motor in general starts at a low rpm and the torque decreases as the speed increases.
This 4 wire bipolar stepper has 18 per step for smooth motion and a nice holding torque. Nema 17 is a hybrid stepping motor with a 18 step angle 200 stepsrevolution. On the other hand the diagram is a simplified variant of this structure. A stepper motor also known as step motor or stepping motor is a brushless dc electric motor that divides a full rotation into a number of equal steps. Nema 17 step motor wiring diagram you should know oyostepperover stepper motor wiring diagram the diagram provides visual representation of a electrical structure. It can control both the speed and the spinning direction of most stepper motors like a nema 17.
Nema 17 stepper motor is generally used in printers cnc machines and laser cutters. Each phase draws 12 a at 4 v allowing for a holding torque of 32 kg cm. This is a datasheet of a nema 17 6 wire which can be connected as bipolar or as unipolar. The motor was specified to have a max current of 350ma so that it could be driven easily with an adafruit motor shield for arduino. Based on old verstion we have lengthened motor cable length to 1 metre and add a 4 pin 01 pitch 254mm harwin female connector at the end of cable. This is an updated version nema 17 stepper motor with holding torque of 59ncm836ozin.
The motors position can then be commanded to move and hold at one of these steps without any position sensor for feedback an open loop controller as long as the motor is carefully sized to the application in respect to torque and speed. This driver board is usually used to control dc motors but it is also an inexpensive alternative to control stepper motors. This bipolar nema 17 stepper motor with step angle 18deg and size 42x42x39mm. Speaking specifically of holding torque the datasheet shows that if you turn the motor on a unipolar driver it loses 30.
