Nema 23 is a stepper motor with a 2.3 x 2.3 inch faceplate. It is suitable for 3d printer, robot arm, cnc machine,etc. In low-speed applications, the stepper motor can be driven at the desired speed without missing a single step.
This stepper motor has different torque, the max torque is 3 Nm. We provide nema 23 stepper motor datasheet and torque curve. The torque is different for each operating speed, but decreases as the stepping speed increases. The reason is the operating principle of the stepper motor. The drive signal of the stepper motor generates a magnetic field in the coil of the motor to generate a step force. The time it takes for the magnetic field to reach its maximum intensity depends on the inductance of the coil, the drive voltage and current limit. As the drive speed increases, the coil maintains its full strength for a shorter period of time and the torque that the motor can produce decreases.

The WS2811 is 3 output channels special for LED driver circuit. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit.Also include a precision internal oscillator and a 12V voltage programmable constant current output drive. In the purpose of reduce power supply ripple, the 3 output channels designed to delay turn-on function.
IC use single NZR communication mode.After the chip power-on reset, the DIN port receivedata from controller, the first IC collect initial 24bit data then sent to the internal data latch, theother data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade IC through the DO port. After transmission for each chip,the signal to reduce 24bit. IC adopt auto reshaping transmit technology, making the chip cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
1. Output port compression 12V.
2. Built in stabilivolt, Only add a resistance to IC VDD feet when under 24V power supply.
3. Gray level 256 can be adjusted and scan frequency not less than 400Hz/s.
4. Built in signal reshaping circuit,after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
