Simple electronic commutator for a dc motor

الملخص EN

The commutator is the weak point of any DC motor and its wear may limit the motor life, however it is an essential part of any DC motor and the commutatorless DC motor is not a true.

Many types of brushless DC motors are available now.

They have a permanent magnet synchronous motor structure and are driven by special controllers.

These controllers are mainly inverters which are considered as electronic commutators.

With using solar energy which gives pure DC voltage, it is more suitable to use DC motors or DC drives which can be fed from this kind of energy.

In this paper we will introduce a simple electronic commutator design which is based on a single chip.

The proposed controller is small enough to be integrated with the motor.
