28BYJ-48 ULN2003 5V Stepper Motor + ULN2003 Driver Board for Arduino - 5pcs

A stepper motor is a type of electromagnetic device that moves in discrete steps.

It has several coils; the central shaft has a series of magnets mounted on it, and the coils surrounding the shaft alternately receive current or not, creating magnetic fields that repel or attract the magnets on the shaft, causing the motor to rotate.

This 28-BYJ48 unipolar stepper motor is supplied with five wires and four coils.

The center connections of the coils are linked together and are generally used as the power connection. They are called unipolar steppers because power always arrives on this pole. A four-phase LED (A, B, C, D) indicates the operating status of the stepper motor. Stepper motor with a standard interface, plug-in when used. Specification: Rated Voltage: DC5V 4-phase Insulation Resistance: > 10 MΩ (500 V) Dielectric Strength: 600V AC / 1mA / 1s Step Angle: 5.625 x 1/64 DC Resistance: 200Ω ± 7% (25C) Reduction Ratio: 1/64 Insulation Class: A No-load Pull-off Frequency: > 600Hz No-load Pull-off Frequency: > 1000Hz Pull-off Torque: > 34.3mN.m (120Hz) Detent torque: > 34.3mN.m Temperature rise: <40K (120Hz)
