What Is NEMA 34 Hybrid Stepper Motor

The NEMA 34 Hybrid stepper motor is a specific type of stepper motor that adheres to the NEMA (National Electrical Manufacturers Association) standard for motor frame sizes. The "34" in NEMA 34 indicates the frame size of the motor, specifically a 3.4-inch square flange ( 86x86mm). Hybrid stepper motors, including those in the NEMA 34 category, combine features of both permanent magnet (PM) and variable reluctance (VR) stepper motors, hence the term "hybrid." In this Blog, we will have a deeper understanding of NEMA 34 hybrid stepper motor, including its dimensions, specifications, and features.

NEMA 34 hybrid stepper motor specifications 

 

1. Step Angle:

NEMA 34 hybrid stepper motors typically have a step angle of 1.8 degrees, meaning they move in increments of 1.8 degrees per step. The finer the step angle, the smoother and more precise the motor's movement, making NEMA 34 motors suitable for applications requiring accuracy.

 

2. Torque:

These NEMA 34 motors are known for their high torque output. The torque varies depending on the specific model, but it is generally higher compared to smaller NEMA motors.  SIT offers three standard NEMA 34 models for clients with a rated torque of 2.57Nm, 6.5Nm, and 8.6Nm.

 

3. Current Rating:

The NEMA 34 hybrid stepper motors in SIT are available in two rated currents, 3A and 6A. A higher current rating allows for more power and, consequently, greater torque, making these motors suitable for heavy-duty applications.
