NEMA 23 frame is next bigger size than NEMA 17 stepper motor. They excel in applications that require precise positioning such as CNC machine tools, 3D printers, camera platforms, and X, Y plotters. GEMS have NEMA 23 steppers with standard 200 steps to one revolution (0.9 degree per step) as well as 400 steps to one revolution (1.8 degree per step). Our high torque NEMA 23 motors are able to generate holding torque up to 355 oz-in (2.5 N.m). GEMS offer various custom motor options, such as integrated encoders, sprockets and pulleys. A number of NEMA 23 planetary geared stepper motor and linear stepper motors are also available for your selection.
Our 60HS series steppers have the same mounting holes location as NEMA 23 while its 2.4 x 2.4 inches (60 x 60mm) faceplate is slightly larger. They are known as NEMA 24 stepper motor. For NEMA 23 steppers used in the dusty and wet environments, please check our waterproof stepper motors.
We stock some best-selling models of NEMA 23 Stepper motors (the ones with the pricing info). Please send the quantity and the shipping address to info@gemsmotor.com, and we’ll respond with the shipping cost and a payment link. We accept credit cards, Paypal, wire transfers and Bitcoins.
