Best answer: What is meant by NEMA 34 size motor?

NEMA (National Electrical Manufacturers Association) 34 is a stepper motor with a 3.4×3.4 inch faceplate and 1.8° step angle. Each phase draws 4.0 A, allowing for a holding torque of 42 kg-cm. NEMA 34 Stepper motor is generally used in Printers, CNC machine, Linear actuators and hard drives.

What do NEMA motor numbers mean?

NEMA Dimensions

Letters are used to indicate where a dimension is taken. For example, the letter “C” indicates the overall length of the motor, and “E” represents the distance from the center of the shaft to the center of the mounting holes in the feet.

What are NEMA motor sizes?

Step motors are categorized by NEMA frame size, such as “size 11” or “size 23” or “size 34”. Generally speaking, a size 11 step motor means the mounting face of the motor is 1.1 inches square; A size 23 step motor is 2.3 inches square; A size 34 step motor is 3.4 inches square, etc.

What is the difference between Nema 23 and Nema 34?

The decision between NEMA 23 and NEMA 34 motors is primarily a decision about productivity — NEMA 34 motors can remove material at a higher rate using higher feed rates and deeper cut depths. … NEMA 34 motors can take deeper passes through material and improve cutting speeds, especially on larger machines.
