Motor on a Hall Effect IC

Discount: 10-24 - 5%; 25-49 - 7.5%; 50-99 - 10%; 100+ - 12%

Designed and made in the USAMotor using Hall Effect IC as a sensor. This is our simple version of common industrial brushless motor.

It is fast, quiet, and the most reliable motor that can work for years!

This motor uses standard AA size batteries (not supplied). Included jumper wire allows to experiment with 3 different voltages: 3, 4.5 and 6 Volts.

Soldering iron required for assembly; you may add an inexpensive one with some solder below.

    Great kit!!!!

    It took me about two hours to put the thing together and it worked great. If I had to guess I would say I was getting about 100 rpm with 4 AA batteries. To make it spin faster you can add more batteries (I tried 4x 6V lantern batteries and it was spinning really really fast).

    I also removed the batteries, connected a multimeter, and I spun it really fast with my hands, it output 0.2 mA as a generator.

    The voltage across the coil comes up to be approximately a square wave with min ~1.6V and max about ~4.8V.

    I highly recommend this kit!!!

    Awesome kit. Easy to assemble and works great.

    Great kit! I looked around for simple kits that demonstrated the principles of a BLDC motor, and this one seemed to be the best. It is very well engineered and assembly and wiring is easy. I got about 3400 (free running) RPM on 6 volts using a laser tachometer.Higher voltages will increase RPM of course, but you can also change RPM by retarding or advancing the Hall IC location. You can also easily put a potentiometer in line as well for more precise speed control.

    I have been an engineer for more than 30 years where I involved in research work and machine development in university laboratory and later in semiconductor industry. I was granted a handful of patents from my inventions during my earlier research work, and I continue inventing today. I wanted to build some simple motors myself and learn the basics. I was very happy when I discovered and so I bought a Kit for my experiment on Pulse Motor. The instructions are very clear, product was packed nicely, and THANKS go to Serge for his patience clarifying my questions — very promptly. It took me just a few hours building my first Pulse Motor that works perfectly. I will now take the challenge to modify the simple motor to explore further and learn new things.

    ~ ~ Really Does A Great Job. Thank you.
