Description: Speed:20000R/Min Voltage:12V Size:approx.242*140*70mm Package weight:about 587g (1cm=10mm=0.39inch) Note: The Base is transparent. It comes with kraft paper on the surface.
Feature: High-speed Hall sensor drive, high-speed stability, long service life, high RPM. 12V power supply, can be long and stable operation, no heat. 12-level winding Increase the speed, Added glass sheets,reduce friction. 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. Notice: 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. Notice: 1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.Please allow slight deviation for the measurement data. 3.Please allow 1-2cm error.
Package Included: 1 X Magnetic Levitation Hall Motor
I hooked up the power supply and the lite lit up but nothing happened when I placed the hall sensor near the magnet. After close inspection, the three leads from the transistor were never soldered to the board. Just the heat sink was holding it on. After I soldered the transistor to the board everything worked fine. The rotor was a little out of balance though and it would vibrate like crazy until balanced. Fast motor.
The magnet on the shaft ar the free end was wandering on the shaft do to an adhesion problem. Once repositioned and reglued things were fine. Other than that nice fast motor.
