This is a mini vibration motor suitable as a non-audible indicator. When the input is HIGH, the motor will vibrate just like your cell phone on silent mode. Small vibration motors have been around since the 1960s. Initially they were developed for massaging products, but their development took a new turn in the 90's when consumer
These are standard '130 size' DC hobby motors. They come with a wider operating range than most toy motors: from 4.5 to 9VDC instead of 1.5-4.5V. This range makes them perfect for controlling with an Adafruit Motor Shield, or with an Arduino where you are more likely to have 5 or 9V available than a high current 3V setting. They'll fit
The Small 3V DC Toy Motor gives the mechanical throughput of 150 RPM simply used in different robotics purposes.
Voltage Rating: 6V
RPM : 150rpm
These motors are normally used in toys, robotics purposes.
A unipolar stepper motor has one winding with center tap per phase. Each section of windings is switched on for each direction of magnetic field. Since in this arrangement a magnetic pole can be reversed without switching the direction of current, the commutation circuit can be made very simple for each winding.
