How to use an electric motor from a DVD drive

Many DIY devices require a powerful yet compact electric motor. If you have an old DVD drive, then you can remove the motor from it, and slightly upgrade. After that, the engine torque will increase, while the rotation speed will be at the level of 16 thousand rpm.

Materials:

  • drive unit;
  • enameled copper wire 0.2 mm;
  • Simonk 30A speed controller – http://alii.pub/61pqks

Manufacturing process of a powerful brushless motor

First you need to open the DVD drive to get to its motor. That must be dismantled. To do this, the lid is unscrewed and the train is broken. To disassemble the motor, you need to pry it off with a screwdriver, and it will open without problems.

A core with a winding is removed from the opened motor. After that, you need to remove the wire wound around it. You won’t need it anymore, so no special care is needed.

Next, you have to make a new winding with a wire with a cross section of 0.2 mm. To do this, it is wound on each tooth of the core coil to coil in 3 layers.

It is important to adhere to the presented winding scheme. A single piece of wire is wound without breaks on the 1st, 4th and 7th teeth. Then the second on teeth 2, 5 and 8, and the third on 3, 6 and 9.

The beginning of the windings must be cleaned of enamel, and the leads must be soldered. Then the engine is assembled back.
