Niskonapięciowy, wolnoobrotowy napęd z bezszczotkowym silnikiem prądu stałego

In this paper low voltage small speed drive with DC brushless motor used as a gear of the boat has been presented. This drive consists of the motor and the electronic circuit controlling the operation of the motor. The construction of Low voltage DC brushless motor is based on typical steel sheets used in asynchronous motors. The paper presents the construction and testing results of constructed prototype. Controlling electronic circuit allows changing of turning direction, continuous variation of speed in whole operating range and limiting the current fed from the supply source. Additional functionality of the electronic circuit is fast braking of motor. This drive possesses high efficiency and can be utilized in boats sailing in calm zones.
