Method for commutating an electronically commutated dc motor, and motor for carrying out said method

The commutation method of an electronic commutation type motor is dealt with, and it has the improved commutation procedure which acts between switch-off of a current pulse, and switch-on of the current pulse following this. Here, based on momentary number of rotations, a switch-off time is calculated, and when it reaches at this time, the current supply on a motor from DC power supply is intercepted. Next, the current which the winding which should carry out switch-off is simplistic and drives through two MOSFET transistors and which disappears within winding is supervised. When reaching the value with which this current was reduced, the winding terminal of winding is temporarily changed to high resistance, and a current pulse begins following it.
