• Single channel structure. The structure efficiently cools the motor even in the case of dry water operation.
• Draining structure. The connection between the motor lead wire and the cab tire cable has been drained to prevent the inside of the motor from flooding through a small gap when the cable sheath is torn or the tip is submerged in water.
• Motor protection device. If the motor windings are abnormally heated or overcurrent flows for some reason, the built-in motor protection device detects and automatically shuts off the electrical circuit or issues an alarm signal to protect the motor.
• It is equipped with either "circle thermal protector" or "miniature protector" depending on the output and start system.
