Basic Info
Model No.: 28BYJ48-118A
Product Description
28BYJ48-118A Unipolar Stepper Motor for IP Camera Monitor | Unipolar Stepper Motor for Camera is a type of Unipolar Stepper Motor and also belongs to Stepper Motor.
The unipolar stepper motor operates with one winding with a center tap per phase. Each section of the winding is switched on for each direction of the magnetic field. Each winding is made relatively simple with the commutation circuit, this is done since the arrangement has a magnetic pole which can be reversed without switching the direction of the current. In most cases, given a phase, the common center tap for each winding is the following; three leads per phase and six leads for a regular two-phase stepper motor.
