Stepper Motor Nema 23 13.5kg-cm
Note: This product has been replaced by Stepper Motor Nema 23 19Kg-cm.
Stepper motors are great for position control. They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. These are a special segment of brushless motors. They are purposely built for high-holding torque. This high-holding torque gives the user the ability to incrementally “step” to the next position. This results in a simple positioning system that doesn’t require an encoder. This makes stepper motor controllers very simple to build and use.
This is a Unipolar stepper, if you are going to drive it with a bipolar stepper driver, you can ignore the yellow and white leads and drive it using the remaining four.

The following diagram shows the stepper motor dimensions in mm.
- Low cost for control achieved
- High torque at startup and low speeds
- Simplicity of construction
- Can operate in an open loop control system
- Low maintenance
- Less likely to stall or slip
- Will work in any environment
- Can be used in robotics in a wide scale.
- High reliability
- The rotation angle of the motor is proportional to the input pulse.
- The motor has full torque at standstill (if the windings are energized)
- Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is non-cumulative from one step to the next.
- Excellent response to starting/stopping/reversing.
- Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
- The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
- It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
- A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
- Require a dedicated control circuit
- Use more current than D.C. motors
- Torque reduces at higher speeds
- Resonances can occur if not properly controlled.
- Not easy to operate at extremely high speeds.
