As a result, this motor gives a wide speed range in one compact gear motor body. Moreover, the 4mm shaft helps connect small drive parts.
Model: NFP-GM25-BL2838, 12V DC
First, the 12V DC version is useful for compact 12V drive systems. Also, the table below helps users compare ratio, gearbox length, speed, current, torque, and stall data.
Therefore, users can choose a low ratio for higher speed. In addition, users can choose a high ratio for stronger low-speed torque.
