Stepper motor is used for precision level controlling. The 28BYJ motor is a very common stepper motor and this can be used in various types of applications where precision control is required.
The specification consists of 5V operating voltage and has a step angle of 5.625 degrees. Thus, 64 steps make 360 degrees of complete rotation of the motor. The friction torque and pull in torque of the motor is 1200 gf.cm and 300 gf.cm respectively.
As this is a four-phase motor, it has five output wires and can be driven with a ULN2003 driver board. A complete set of this stepper motor with an ULN2003 board is also available in quartz components. It operates on 5V and has a step angle of 5.625 degrees, meaning it has to make 64 steps to complete one rotation.
The connector has 2.54” spacing.
