How the 775 DC Motor Works

The 775 motor operates on the fundamental principle of electromagnetic induction. When DC voltage is applied to the motor terminals, the following process takes place:

• Current flows through the armature windings
• A magnetic field interacts with the internal permanent magnets
• This interaction generates rotational force (torque)
• The motor shaft spins at high speed

Motor speed can be precisely controlled using a PWM motor driver or through voltage regulation, giving users full control over performance output.
