I want to make this motor work, but I can't understand what type this is. I supplied 5V DC to the terminals, but it just kept buzzing and the coils were energized. It also had some kind of circuit, but it was not connected to any of the terminals. What do you guys think?

    \$\begingroup\$ "some kind of circuit" looks like a Hall effect sensor, which sends timing signals (about the rotor speed) to the motor controller circuit. \$\endgroup\$ – Brian Drummond Jan 19 '19 at 11:53
  • \$\begingroup\$ Seconding @Chu, this looks like a permanent-magnet AC motor, also called a brushless DC motor. Only single-phase though. \$\endgroup\$ – Hearth Jan 19 '19 at 15:00

It's an single phase BLDC (Brush less dc) motor. the circuit is an hall effect sensor to detect the rotor position.

Some thing similar to this enter image description here follow this link for more information on control and working of an single phase BLDC motor
