4.2kg.Cm High Torque Stepper Motor 2 Phase Nema17 stepper motor for cnc robot

A stepper motor is an device that moves in discrete steps. It has several coils that are organized into phases. When every phase is energized in turn, it causes the motor to step. With the stepper motor, you can get precise positioning and speed control. There are maily 3 methods a stepper motor can be driven. The 3 driving ways are full-step drive, half-step drive, and microstepping.

To select the proper stepper motor, you need such data such as frame size, step angle,torque, rated Amp, number of wiring leads, and etc.

To drive a stepper motor you usually need the following equipment:

Stepper motor
Stepper motor driver
Controller
Switching power supply

How to Choose a stepper motor

1.You need to select the right stepper motor for your speed and torque requirements

Usually there is NEMA8, NEMA14, NEMA17, NEMA23, NEMA34 and NEMA42.

Nema: Nema is not a standard for the electrical characteristics of stepper motors. It is simply refers to the faceplate size. For example NEMA17 means the frame size is 42MM.

2.Holding torque: The holding torque is the amount of torque required to move the motor one full step while the coils are energized and the rotor is stationary. The stepper motor winding is energized even if the rotor itself is stationary. This is to maintain the load in place while stationary.

3.Shaft Type: You need to know the physical shape of this motor shaft to match your stepper motor to pulleys, gears, and other external connections such as shaft couplings. There are several common shapes. Also, the length of the shaft needs to be considered.

Some common shafts are listed below:

Round Shaft - round shaped shaft
"D" Shaft - a "D-shaped" shaft that is useful for mounting gears with set screws.
KEYWAY shaft
Lead-screw shaft - a shaft shaped like a screw, used for building linear actuators.

Rated Current: This refers to the peak current. This is a useful specification because it allows you to select a suitable driver and power supply for your stepper motor.
