Look at these wikicommons pictures. Taking apart a CD player and finding the motor is fairly easy.Start by turning it upside down and removing the screws holding the bottom plate on.

Electronic motors are found in kids toys, RC cars, airplanes and helicopters, printers, scanners, and fax machines. They are expensive when purchased, quantity 1, new with manual. This is because the motors are part of a supply chain that is usually just making enough to fill orders for kids toys, etc. Many can be found for sale on the internet, but very few are in stock and the price is high if they are. Often it is easier to purchase the kids toy and take it apart. The goal is to connect these motors to the arduino and then make something new with them. The goal of this document is to describe what to expect.

But they can also spin like a DC and Brushless Motor. They can not hold their position as strongly as a servo motor, and they can not spin as fast as a brushed or brushless motor.

Dithering the stepper signal at a higher frequency than the motor can respond to will reduce this "static friction" effect. Because windings are better utilized, they are more powerful than a unipolar motor of the same weight. This is due to the physical space occupied by the windings.

As the motor rotor turns, a sinusoidal voltage is generated proportional to the speed (step rate). This AC voltage is subtracted from the voltage waveform available to induce a change in the current.

This IC is available only in an 8-pin dual-flat no-leads (DFN) package, measuring a scant 2.5mm × 2.5mm with a tiny thickness of only 0.9mm. There is also, in addition to the eight pins, a thermal pad that is connected to ground (see image below).

Due to their non-standard dimensions, the oddly shaped, thin, or fragile boards do not fit properly in the reflow, component placement, or other standard processing machines. Lack of adequate support and alignment may strain, bend or damage the fragile boards as they go through the processing system. In addition, this may impact the accuracy of the process.

Although this device uses an I2C interface with communication speeds up to 1 MHz, two of the eight pins are dedicated to Alert (pin3) and nReset (pin 6). The Alert pin is intended to be connected, if desired, to an interrupt pin on a microcontroller. According to section 3.5 (ALERT Pin) of the datasheet, "The output of the pin depends on the value of the temperature reading relative to programmable limits," and its function is "explained in a separate application note.
