Nema 17 23 And 34 Frame Sizes

A stepper motor is used to achieve precise positioning via digital control.

Nema 17 23 and 34 frame sizes. Stepper motor nema sizes nema is national electrical manufacturers association and their standard for motor mounts is commonly used in the industry to ensure that replacement parts will fit and be readily available and that motors from different mfgs will be interchangeable. The frame number relates to. Horsepower built in different frames. Typical examples of frame numbers 48 56 145 and 215.

The nema number is related to the diameter of the motor times 10. Stepper motors with their ability to produce high torque at a low speed while minimizing vibration are ideal for applications requiring quick positioning over a short distance. Choose from our selection of nema motors including over 225 products in a wide range of styles and sizes. Size 24 is somewhat of an outlier there is no formal nema definition for size 24.

Dimensions can be less than indicated. These high torque synchronous motors are available in nema 23 34 and 42 frame sizes 60 90 and 110 mm providing up to 1 500 oz in 1 059 n cm of torque.

Step motors are categorized by nema frame size such as size 11 or size 23 or size 34. It mounts like a size 23 but is slightly wider about 4 mm allowing for a larger rotor and stator and thus about 30 more torque. The national electrical manufacturers association nema defines a set of standards used to dictate tolerances for many products including step motors. Nema national electrical manufacturers association frame size refers to mounting only and has no direct bearing on the motor body diameter.
