Universal menu system for devices with rotary encoder with push and SSD1306 I2C display by @mikosoft83 That means there are 32 steps per revolution (360/11.25 = 32). Unlike a brushless DC motor, which rotates continuously when a fixed DC voltage is applied to it, a step motor rotates in discrete step angles. The center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate. Stepping motors can be viewed as electric motors without commutators. Member Since: May 2, 2019 Location: Saudi Arabia More by Author. So, to sum it up.
