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.Jun 1, 2015
What is NEMA motor size?
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 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 does NEMA 23 stand for?
Step motors are categorized by frame size, such as "size 11" or "size 23". Generally speaking, "size 11" mean the mounting face of the motor is 1.1 inches square. So a Size 23 step motor is, wait for it, 2.3 inches square. Or 56.4 mm as shown below.
What does NEMA 11 mean?
1.1 inches square

What is a 42 stepper motor?
A Nema 42 stepper motor is a stepper motor with a 4.2 x 4.2 inch (110 x 110mm) faceplate. These motors are engineered to provide the highest possible torque but minimize vibration and audible noise.
What do NEMA sizes mean?
The National Electrical Manufacturers Association sets standards for many electrical products, including step motors. Generally speaking, "size 11" mean the mounting face of the motor is 1.1 inches square. So a Size 23 step motor is, wait for it, 2.3 inches square.
