NEMA-17 BLDC (brushless dc) motors handle high-speed and high-dynamic-torque applications.
Optimal performance speed is 300 to 3,000 rpm. These motors offer velocity control with an analog input and need no holding torque. They come in stack lengths of 1.61, 2.40, 3.19, and 3.94. Depending upon stack length, the motors can produce up to 106 oz-in. of peak torque.
