Pancake motors or printed armature motors and servodisc motors as they are also known, are employed for various industrial applications wherever rapid stop-start, zero cogging, low inductance, precise electronic motor control, a low thermal time constant or just a slim, axially flat packaging profile is needed.
How does a motor work simple explanation?
The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. When an electric current starts to creep along a wire, it creates a magnetic field all around it.

How does an electric magnetic motor work?
An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
How does a servo motor turn?
A servo motor can usually only turn 90° in either direction for a total of 180° movement. Shorter than 1.5ms moves it in the counter clockwise direction toward the 0° position, and any longer than 1.5ms will turn the servo in a clockwise direction toward the 180° position.
How does an RC servo motor work?
Servos are controlled by sending them a pulse of variable width. As long as the signal pulse exists on the signal line, the servo will maintain the angular position of the shaft after it has rotated to that position. As the signal pulse changes, the angular position of the shaft will change.
How does a servo motor hold position?
Servos will not hold their position forever though; the position pulse must be repeated to instruct the servo to stay in position. When a pulse is sent to a servo that is less than 1.5 ms the servo rotates to a position and holds its output shaft some number of degrees counterclockwise from the neutral point.
What is inside a servo motor?
Inside there is a pretty simple set-up: a small DC motor, potentiometer, and a control circuit. The motor is attached by gears to the control wheel. As the motor rotates, the potentiometer's resistance changes, so the control circuit can precisely regulate how much movement there is and in which direction.
How does a servo motor work?
How does a servo motor work? A servo motor is an electromechanical device that produces torque and velocity based on the supplied current and voltage. A servo motor works as part of a closed loop system providing torque and velocity as commanded from a servo controller utilizing a feedback device to close the loop.
