Descriptions: A stepper motor, also known as step motor or stepping 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 position sensor for feedback, as long as the motor is carefully sized to the application in respect to torque and speed. Features: Small step angle High positioning accuracy High torque to inertia ratio Stepping rate and accuracy Specification: Stepper Motor Type: 28BYJ-48 Driver Board: ULN2003AN A, B, C, D four-phase LED indicates the status of the stepper motor work. Stepper motor with a standard interface, when used directly pluggable. 5 line 4 phase can be used for ordinary ULN2003 chip driver, connect to the 2 phase , support the development board, with convenient use, direct docking. Rated Voltage: DC5V 4-phase Insulation Resistance: >10MO (500V) Dielectric Strength: 600V AC / 1mA / 1s Step angle: 5.625 x 1/64 DC Resistance: 200O±7% (25C) Reduction ratio: 1/64 Insulation Grade: A No-load Pull in Frequency: >600Hz No-load Pull out Frequency: >1000Hz Pull in Torque: >34.3mN.m(120Hz) Detent Torque: >34.3mN.m Temperature Rise: <40K(120Hz) Package Includes 5 x Stepper Motor 5 x ULN2003AN Driver Board 30 x Female-to-female jump wire
