Abstract
An underwater propulsion apparatus includes a motor and a control system for controlling the motor. The control system includes a remote controller and a motor driving device, wirelessly communicating with the remote controller. The motor driving device includes a communication repeater module and a motor driving module. The communication repeater module is configured for detecting interruptions or non-receipt of a wireless signal transmitted by the remote controller. Wireless signals to the motor driving module are transmitted by the remote controller to the communication repeater module. The motor driving module is configured for receiving the wireless signal, and outputs a driving signal for driving the motor according to the wireless signal, the motor driving module shutting down when no signal is received.
