Nema11  stepper motor 11HR05-0404S ( round )    0.9 deg,  0.3 A,  4 N.cm 
(5 sets / lot)
   
The 11HS Series DC Stepper Motor have bigger size than Nema 8HS DC Stepper Motor, but have much bigger torque than the latter. These DC Stepper Motor were designed to offer the highest possible torque while minimizing vibration and audible noise. Unlike DC motors, the 11HS series DC Stepper Motor already has a very high torque at low speed and often gears are not required which leads to considerably more economical drive solutions. The standard 4 lead wire DC Stepper Motor can be connected to allow the flexibility for your application. OSM can also customize the winding to perfectly match your voltage, current, and maximum operating speed.
 
Main Application:
Inject printers, Analytical and Medical Instruments, Textile Equipment, Embroidery Machine, Precision Telescope Positioning Systems, High Speed Dome Camera and Robotic
  A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor\'s position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.   Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.   Fundamentals of operation DC brush motors rotate continuously when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple "toothed" electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit, such as a microcontroller. To make the motor shaft turn, first, one electromagnet is given
