Reciprocating Hall Motor with two coils High-speed Magnetic Motor brushless motor DIY TOYS

 Main Features:

  •  High-speed Hall sensor drive, high-speed stability, long service life, high RPM.
  •  It was complete kit, already finish assembled, just take and play.
  •  Good for education demonstration, also suitable for students to demonstrate and increase their interest in science.

General Information:

Overall Size: 138*110*75mm

 ATTENTION:

  •  Do not touch the rotor when it operation in high speed.
  •  Need to be placed on a horizontally stationary table, do not shake.
  • Be sure to protect the sensor.

 

  •  Why can the cams revolve without motor?

  After power on, drive the cams by hand to let the magnets through the sensor then the coils can generate electricity to make a magnetic field to revolve the cams.

  • Why the cams can revolve continuously when the force is constant?

  It has an ingenious structure. There are magnets on the rotary cams and a senor below them. When the north pole of the magnets closes to the sensor, it can control the power   supply. Rotary cams will revolve by the inertia after movement, and that the cycle repeats, the cams can swing and revolve continuously.

  • What is the advantage compare to the single coil?

  The more coins can increase the power and the rotation speed, and the structure is more complex
