The 28mm NEMA 11 stepper motor is an externally driven ball screw straight stepper motor with a through-shaft type. The nut of this motor is integrated with the motor rotor, and the screw shaft passes through the nut in the center of the motor rotor and drives a plunger forward and backward. The plunger is supported by a guide sleeve on the motor, which can realize the automatic forward and backward of the rotating shaft (plunger), and does not require other separate auxiliary action on the screw or nut.
The 28mm NEMA 11 stepper motor has the characteristics of small size, high performance, long durability, low noise and high efficiency.
When purchasing a 28mm NEMA 11 stepper motor, it is necessary to choose according to the application scenario and load requirements. For example, select the motor length, screw lead, screw stroke, etc. according to your needs. At the same time, it is necessary to consider the speed of the motor, working temperature, ambient humidity and other factors to ensure the stability and reliability of the motor.
