In the world of conventional hybrid step motors, the Pacific Scientific brand plays the leading role. You can find dozens of reliable motors, and one of them is the E21NRFT-JDN-NS-02. Here is what makes this unit specific, and why it may be the ideal choice for you.
The motor is a part of the E21 series of hybrid step motors. These are equipped with the so-called Sigmax technology, which was developed by the manufacturer. Its goal is to ensure improved torque and acceleration, which both contribute to enhanced performance.
The unit uses the NEMA mounting configuration, and its frame size is “23.” It is one of the most compact motors by this manufacturer, but it still packs a decent amount of power. The frame diameter is 2.25 inches, and it weighs only 1.2 pounds (0.55 kilograms), which means space shouldn’t be a problem.
Due to the T winding that E21NRFT-JDN-NS-02 utilizes, the motor can deliver maximum torque when it works at low speeds. Combined with low inertia, that should secure consistent performance if that is what you need from your hybrid step motor.
When it comes to the installation process, you can expect regular construction and lead-wire hook up. A double shaft configuration with smooth modification is another important feature of this unit. Although the manufacturer marked it as a motor that doesn’t belong to standard configurations, you shouldn’t expect any encoder feedback.
It is nice to see that E21NRFT-JDN-NS-02 was made of parts of superb quality. Thanks to that, the unit can last for years to come as long as you secure optimal working conditions. Overall, it is a reliable hybrid step motor that can deliver excellent results.
