NEMA34-02
The NEMA34-02 is a high-performance, bipolar, hightorque stepper motor designed for demanding drive and positioning tasks. Thanks to its robust NEMA 34 design, it is particularly well-suited for larger CNC, automation, and robotics applications where high forces must be transmitted reliably.
With 200 steps per revolution and a step angle of 1.8°, the motor enables precise and controlled movement. This allows even heavier mechanical axes to be positioned with reproducible accuracy and driven reliably.
The holding torque of 3.8 Nm provides a high power reserve for high-performance applications. At the same time, with an overall length of just 76 mm, the motor remains relatively compact, making it particularly well-suited for designs that require high performance in a limited installation space.
The robust 14-mm shaft with a double flat ensures a secure mechanical connection to couplings or other drive components. Four open connection wires also allow for flexible electrical integration into a wide variety of control systems and machine designs.
