NEMA 23 Stepper Motor; Specifications, Applications, and How to use one

Motors are essential components when converting the energy in your systems connections. Importantly, for electronics enthusiasts looking for motors, your priority is to find a reliable motor with high motor efficiency. Therefore, this article discusses the nema23 stepper motor, its pin configurations, specifications, applications, and how to use one in your connections.

1. What is the Nema 23 Stepper Motor?

The NEMA 23 is mostly a hybrid bipolar stepper motor with high torque. Additionally, the motor is a 2-phase stepping motor used to generate power. Notably, it stands out because its step angle is 1.8 degrees. With this angle, there are 200 steps for every single turn. Therefore, each revolution of this dual-shaft motor covers 1.8 degrees.

Also, the motor’s design focuses on delivering maximum torque at operating speeds. As a result, the design reduces vibration and noise. Thus it is preferred in precision motion controllers.

2. Pin Configuration

Notably, the nema23 motor wirings have four wires that are different colors. These are; (Black, Green, Red, and Blue). However, these wires are uncovered.

Simply, one coil is wired with black and green wires. However, the remaining coil attaches to the red and blue wires. Additionally, using two H-bridges can control this motor. But, keep in mind that you should always use a motor drive. 

3. Specifications of the Nema-23 Stepper Motor. 

  • Firstly, its operating motor driving voltage is 3.2V
  • Second, the current working rating is 2.8A

5. How to use NEMA 23 stepper motor?

Particularly, this stepper motor needs a lot of power for torque-speed performance. Therefore, instead of directly monitoring it with H-bridges, use a powerful stepper motor driver. Moreover, to make this motor move, we must look at the coil diagram below.

Notably, from the diagram above, our NEMA23 motor has four wires. All wires have different colors. Significantly, the motor can only move if the coils turn on in a logical order. Importantly, a microcontroller may easily set up the motor driving procedure. Also, you can make a digital circuit instead.

Note; Always check the stepper motor datasheet for additional information.
