船舶推进电机保护装置

Start-up Protecting Device for Marine Propulsion Motor

针对某型船舶推进电机启动、转向时所存在的安全隐患,设计了一种电机保护装置,以防止推进电机在启动或转向时,因电枢电流过大而对电机造成的危害.

To counter unsafe problems that may emerge while a marine propulsion motor starts-up or changes its rotation direction, a new protecting device is developed. Adding the device to the existing control system, the marine propulsion motor can be protected from excess armature current during its starting-up or changing rotation direction.
