The “NEMA 34” designation indicates a frame size of 3.4 inches (approximately 86.36 mm) square, providing substantial torque and power for demanding applications. The hollow shaft design is particularly useful in applications where space is limited or where direct connection to other mechanical components is needed, such as in robotics, CNC machines, and automated systems. This motor offers precise control and high performance while facilitating a cleaner and more efficient setup.
