There are two types motors used. Both are DC, the one that is used to open and close the CD reader is a Stepper motor. The other type is a BLDC (brushless DC ) motor that is used to spin the CD.
Which motor is used in CD drive?
The motor used to spin the CD or DVD is a brushless motor, that means that you can’t simply connect two wires in a battery and it will spin, for that, you will need a Electronic Speed Controller (ESC) and maybe some mods , following are some instructables with motors like this.
Does CD player uses an electric motor?
The process of playing an audio CD, touted as a digital audio storage medium, starts with the plastic polycarbonate compact disc, a medium that contains the digitally encoded data. … An electric motor spins the disc.
What is disc drive motor?
Disk drive motors are quite nice motors quite accurate speed control system. Disk drive motors rotate the disk at 300 or 360 rpm speed. Standard drives use 300 rpm, but high-density drives use 360 rmp or selectable speed 300/360 rpm motors.
What is the different between CD and DC?
The difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, or “forward.” In AC, electrons keep switching directions, sometimes going “forward” and then going “backward.”
Does washing machine use electric motor?
All of the parts are the same, they are just powered one way to make a motor and another way to make a generator. Some types of washing machine use large DC motors that can be removed along with their axles and bearings and reused as generators.
Does food blender uses an electric motor?
The motor portion of a blender is actually a very simple design as it is usually a small air-cooled electric motor which is located in the housing portion of the blender. The motor is designed to case a small coupler shaft to spin.
How long do CD players last?
CD players aren’t as long-lived, though they can deliver 5 to 10 years of service.
Do they still make CD players?
Music producers as well as electronics manufacturers may eventually make the decision to discontinue the production of CDs and CD players.
How long do CDs last?
Among the manufacturers that have done testing, there is consensus that, under recommended storage conditions, CD-R, DVD-R, and DVD+R discs should have a life expectancy of 100 to 200 years or more; CD-RW, DVD-RW, DVD+RW, and DVD-RAM discs should have a life expectancy of 25 years or more.
What can I do with an old CD drive?

What type of motor is a stepper motor?
Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.
Why DC is not used in homes?
The answer to why DC current is not used in homes goes back to the inherent characteristics of direct currents and their weaknesses compared to Alternating Currents (AC). In fact, AC currents can be easily transmitted over long distances without much loss. They are also safer in direct touch at an equal voltage.
What does DC stand for?
It is a federal district. The President of the USA and many major national government offices are in the territory. This makes it the political center of the United States of America. Washington was named after the first U.S. President George Washington. “D.C.” stands for “District of Columbia”.
What devices use DC?
Direct current is used in any electronic device with a battery for a power source. It is also used to charge batteries, so rechargeable devices like laptops and cell phones come with an AC adapter that converts alternating current to direct current.
