Title:
BRUSHLESS MOTOR
Document Type and Number:
Japanese Patent JP2005304192
Kind Code:
A
Abstract:
To provide a connector for not generating a reverse voltage and a reverse current when a higher-level controller board and a brushless motor are connected.
A GND pin 3 of the female connector 2 on a brushless motor board 1 is longer than a connection pin 4 for 24 V, a connection pin 5 for 5 V, an input pin 6 and an output pin 7. When the male connector 8 on the higher-level controller side and the female connector 2 on the brushless motor side are connected, a voltage is applied relative to the GND since the GND pin 3 is connected prior to the other pins. The reverse voltage and the reverse current are not generated and the brushless motor is prevented from being damaged.
